I thought I saw the wires reversed when you first showed the battery and then I thought…nah maybe it’s different for the Briggs vs the Tecumseh. Good job. Great explanation.
Thanks for watching and taking the time to leave a comment. Cheers
The reversed wires was my first guess when you showed that it wasn't bound up good job and i enjoyed the video , keep them coming
Appreciate it. Thanks for watching. Cheers
Great diagnosis . I’m old but there is a name for the centrifugal climb clutch , new subscriber. I still love to fix small engines,
Thanks for the sub. Hope you enjoy the channel. Cheers
I’ve got a Toro Personal Pacer mower with the 6.75 hp B&S engine. The electric start will spin the motor but not quite fast enought to start it. It has a new 12V 7.2AH battery, fully charged, new float this year, new magneto a year ago, and valves adjusted to spec. I can spin the engine by rotating the blade by hand and with a compression tester installed, it's reading 0 psi which makes sense if the compression release mechanism is working properly. You can give it one tug on the pull start it will fire up and run perfectly. I've got an old Sears battery charger (2, 10 & 50 amp) with small connectors that I can fit on the battery. At the 10 amp setting, it's just enough extra juice to spin the motor a bit faster and start it. Today, I pulled the electric starter and added a bit of oil on the bearings. I can spin it by hand and there's very little resistance. Reinstalled and it made no difference. I'm strumped.
Couple of thoughts. Your compression tester must be bad if it's reading 0 but the engine will run. With a compression release, you should still read probably 40-80psi.
Use a multimeter to check the voltage of your battery. It should be higher than 13V. If not then fully charge it.
Make sure all connections are tight and there is no corrosion.
Make sure the connections are not reversed.
Is it the proper battery for the mower? Not only does it have to be 12V, it has to have the proper Amperage. Too low and it will not spin fast enough.
Hope you figure it out. Cheers
LOL their issue was a bit of a freak, but thanks for your video. Too many youtubes are focussed on self promotion, music graphics and "hit my like" --- I liked your no nonsense informative approach. I recently acquired the same machine, self start button does nothing, will try to charge the battery as you showed me how to access.
Glad it helped! Thanks for watching and taking the time to leave a comment. Cheers
My Toro mower is 13 years old electric start stopped all at once. There is a fuse at the battery connection will replace will follow your ideas. I do not
like to pull on the pull rope many times. If all else fails I have used starter fluid...one short blast, one pull mower starts. I used starter fluid for
3 years on my last mower, mower kept running but I sold the mower when I bought the torro. Never let a mower get too hot.
If you're using starter fluid and it starts and continues to run, you have a problem with me priming or choke system, whichever one your engine has. Thanks for watching and taking the time to leave a comment. Cheers
thanks for the video. was able to locate and lube the starter gear and started right up. (my battery was new)
Glad I was able to help and thanks for taking the time to add a comment. Cheers
I have not had much to do with electric start push mower's, but if they are maintained properly like any other mower should be, then in my opinion they would be ok.
Nice catch on the reversed polarity wiring.
The electric start is usually the first thing to go because of improper use, maintenance and cost, at least here in Canada. People end up losing the charger. Replacement batteries are expensive also. I end up usually not fixing these electric start systems due to cost, unless it's pretty new. This just happened to be an easy one. Thanks for watching. Cheers
Thx , agree 😊
Very informative
Appreciate it. Thanks for watching. Cheers
Thank you,
You are welcome! Thanks for watching. Cheers
Hey, since these are flathead engines, the valves are only adjustable via the old-school grinding method right? I had a mower with electric start that, on the compression stroke, the starter wasn't strong enough to turn the engine over. It was a new battery, but I should try to also add my booster/jumper pack and see if maybe the new battery wasn't charged enough yet. I cleaned all connections except at the push button switch on the handle.
That's correct, you'd have to take the valves out and grind the stems. It's a laborious process
@@brantsmallenginerepairs ah yea, I've done it on an old cast iron 10hp, if it becomes more of an issue, I'll at least check the valve lash in them
@@M.TTT. that is fairly easy to do. As the lash gets smaller though, compression would go down though, not up. Some things you might want to check for high compression or hard to turn over: make sure there isn't oil getting into the cylinder causing hydro lock, check the flywheel key to make sure it's not partially or fully sheared, possible issue with compression release.
@@brantsmallenginerepairs yea, thats what I was thinking, I'll have to double check the oil in cylinder, I replaced the flywheel key as it was very very slightly indented, and yea could be a worn compression release lobe on the crank in there, not sure. The lash would be greater though with wear and tear, so new valves properly gapped may help if needed.
Great job. I learned a few things for sure. I think my Charger is bad. Do you know what I should be reading for DC voltage from the wall charger? I'm NOT getting 13.2V. I'm only getting like 1V. But I wasn't sure if it was some sort of "smart" charger and didn't put out any voltage without a battery connected. Thank you!
I'm not sure what the output would be directly from the wall. You would think it would have to be more than 13V. Maybe try connecting the charger to the mower and read the voltage from the connections on the battery. If it's not more than 13V there with it plugged in and "charging" then you might have a bad charger. Hope this helps. Cheers
@@brantsmallenginerepairs Thanks. I'll wear it down a bit and see what the voltage is on the battery. Then plug in the Toro wall charger and see if it takes it back up. It's currently 13.2 only because I charged the battery with a small trickle charger. I'm pretty sure that wall charger is toast. I tried measuring it with a capacitor across the terminals too (simulate a battery connected) and still basically < 1 volt.
@@user-iq9qg6lq9x sounds like a new charger is in order or just charge it a couple times a year with the trickle charger
I need to find a replacement charger for my dad's Toro lawnmower. Help lol
@@MeganLavon92 I believe the part number is 136-9126 for the charger. Just search for it on Amazon or Ebay or Toroparts.com
Would you happen to have a starter model number for these toro mowers? Need a new starter :)
I don't have the starter part number off hand. I returned the mower to the customer already. My suggestion would be to find the engine model number and search on a parts supplier website like Jack's small engines or partstree. Hope this helps.
I have the same mower. Electric start worked fine last year. This year…Won’t turn over. Not ever sure it’s charging. Is there a fuse to check somewhere?
I believe there was an inline fuse but I can't remember honestly. Trace the wiring from the battery to the key and you should find it if there is one. Have you tried charging the battery? I don't believe this model has an alternator to charge the battery. Pretty sure you have to charge it once or twice a season using an AC charger that hooks into a harness near the key. Hope this helps. Cheers
if i just want a pull start mower ( bad battery ) do i need to unhook anything or unplug anything to use as a pull start .....
Not at all. Just pull the cord to fire it up.
@@brantsmallenginerepairs thanks.....
So I have the same mower. Battery is fully charged but when I push the starter button it does nothing at all. Almost as if the battery is dead. Any idea?
If the battery is fully charged and you're getting nothing, then the power is not getting to the starter. I believe there is an inline fuse if I recall correctly. I would check that fuse first. If that checks ok, you'll need a multimeter to troubleshoot where the power stops flowing starting at the battery and working your way to the starter. Check all the connections to make sure they are tight. Hope this helps
Hey Brant, I’ve got the same mower but I think it’s a few years newer. Anyhow, I’ve got a problem with it starting. The electric start will crank the motor and it will turn over but it won’t start. However, you can pull it with the pull start one or two times and the mower will fire up and run perfect. I cleaned the gas tank, fuel line, and the carburetor because the person let it sit with old gas in it for a long time. Like I said, if you pull start it, it runs like a champ, but the electric start just turns it over without starting. The battery is new and I also charged it and is hooked up correctly. Also, I noticed when I push the primer bulb, it isn’t shooting gas into the carb, but the bulb is good, I checked for holes and leaks, but everything is ok. Have you seen this issue before and how can I fix it? I’m sure it’s something simple. Any help would be greatly appreciated. Thanks.
The primer issue is likely the gasket between the carb and air filter assembly. Either replace it or just double it up. As for the starter, it sounds like maybe it's not spinning the engine over fast enough? The lack of priming would make it hard to start with electric start and pull start.
@@brantsmallenginerepairs I got to thinking and by pull starting it, you’re spinning the flywheel faster than the starter. Anyhow, I pulled the plug out and turned the motor over with the electric start, checked the fire on the plug and it was weak. It was a new plug. So I took the Callan off and the gas tank to get to the fly wheel. I noticed a little bit of rust on the magnets so I cleaned them up with steel wool. I tried it and it fired up and has started ever since. I do need to probably replace the gasket between the air breather and the carb though.
Great video. I was mowing my yard with my toro lawnmower and out of no where the auto push stopped working but the lawnmower was still running just fine. Do you have any advice on how to fix this?
I just did a deep clean and it really did nothing I’ll try to charge the battery.
When you say auto push stopped working, what do you mean? Do you mean the self propel system that drives the wheels for you?
So the mower won't start using the electric start? Is this the problem? Just trying to fully understand what the problem is.
@@brantsmallenginerepairs yeah
@@brantsmallenginerepairs I have the toro 7.25 190cc and it starts and runs fine it’s just that the self propel stoped working
I have the same mower. It starts easy on rope and cranks long on starter. New battery, new plug, fresh cleaned carb, new air cleaner too! Seems like it cranks slow, and the battery is at 12v. Any suggestions?
I would first confirm the voltage of the battery. It might also need a valve adjustment. Thanks for watching and taking the time to leave a comment. Cheers
Battery charge is good, battery is new and I confirmed the voltage. I thought about valve adjustment, but this isn’t an OHV engine and I’m not pulling it all apart.
Because it’s a DC motor if you reverse the polarity it’ll spin clockwise or counter clockwise
Thanks for watching and taking the time to leave a comment. Cheers
How was the starter getting any power if the leads were reversed.
Reverse polarity would still apply power. Spins the starter in the wrong direction. Atleast that's what was going on here. Cheers
Now what I have is a small briggs engine like yours that will not recharge the battery. The fuse is good, the battery is good. The battery will take a charge and start the engine, but will not recharge the battery. Engine will restart when using the recoil, no problem..
If it's similar to this one, the mower actually does not have an alternator for charging. It comes with a wall plug-in charger. There should be a wire harness to plug the charger into to charge the battery. Hope this helps. Cheers
If the leads were reversed was rhe starter turning the wrong way ?
Yes it was. I didn't notice it at first but you can definitely see that if you look closely. Thanks for watching and taking the time to leave a comment. Cheers
10.9 Volt battery should be week enough not to start the mower. Wonder what voltage would you measure once you corrected wiring to the battery.
Don't recall as this fix was a while ago. Voltage might have been the same, just reversed polarity. Thanks for watching and taking the time to leave a comment. Cheers
Yep, the second you hit that starter I said “Running backwards!”
Thanks for watching and taking the time to leave a comment. Cheers
Excellent trouble shooting.1/7/2022
Appreciate it Frank. Take care!
Replaced bat
Still no start, tested bat, 12v, good but is not charging problem, works by pull start help
@@andreanundal6109 so it's definitely an issue with the electric start. I would start with checking for a fuse and see if that's blown. Next, trace the wiring from the battery to the starter. Use a multimeter or 12V test light and see if you have power at the starter when the key is switched to start. If not then you have an issue in the wiring from the battery to the starter. If there is power then you have a bad starter.
@@brantsmallenginerepairs thanks so much,calling a pro, still will start by pulling
Why does it start with the hand pull?
The pull rope is always available for use, even if the electric start isn't working. Unless the engine is locked up of course
The pull start is always available, even if the electric start doesn't work. Unless the engine is seized of course.
Not worth replacing!? WTF? They’re $20.
Not in Canada they aren't.
@@brantsmallenginerepairsAre they 500 dollars in Canada because that's what the lawn mower costs.
That's exactly what I was thinking?
@@RDCZcams54 you don't have to replace the entire mower because the electric start doesn't work. The pull start still works. Now if you can't physically pull the cord then it's probably worth replacing it. But because I buy and sell for profit, it wasn't worth the extra cost. But thanks for your opinion
Always make sure your negative is on negative and your positive isnd positive if not your starter motor will spit in reverse
Exactly. The owner seemed to forget this. Thanks for watching and taking the time to leave a comment. Cheers
We replaced the battery. Doesn’t turn over.
Is the engine seized? Does the pull rope turn the engine over?
@@brantsmallenginerepairs yes. A friend cleaned up the starter. Recharging the battery. Will try again Sunday. Otherwise starter $126 from b & s. Ty.
Are the batteries expensive to replace? Why can't you just buy a new battery and swap it out after a few years?
They're expensive enough here in Canada. Also, without the ability to charge the battery, you'd be changing the battery every year. It would be dead after winter storage
@@brantsmallenginerepairs I am talking about in my instance. I still have the charger and the original battery (5 years old) is getting much less than 12V. Just from an initial scan on google it looks like they go from $40- $50 on places like Amazon, Home Depot.
I guess I misread your original post. You can replace the battery if it is dead but as you've found out, they aren't cheap. But if you can't pull the rope and need the electric start to work, $50 is cheap compared to $600 plus for a new one with electric start.
Hey! First off, great video. I have a 20067 that's doing the same thing but I don't think it's reversed polarity. I'll investigate and report back.
However, regarding the dead batteries, I just brought the battery with my mower back to life from 0.28dcv. Referring to 4:40 of this video, looking at the opposite end of the battery from the terminals, there's a small hole. I inserted a small pick into that and worked it until the plastic cover came off revealing 8 rubber stoppers that I removed and added distilled water. I replaced the 8 stoppers, put the "lid" back in place and connected the smaller battery to my lawn tractor battery (the voltage on the 20067 battery was so low that my battery charger couldn't recognize it) until I was at about 7dcv. I then connected the battery to my charger, the charger recognized it and charged to 12.38dcv.
This was all done yesterday (20 June) so I'll find out later how this holds up
This video goes into decent detail about what I described...

The wires are right. It’s making the same noise yours is. Just won’t start the engine
Make sure the battery is fully charged. If it's spinning the engine fast enough, then you have a different issue. Try using the pull cord to confirm if it's a starter issue or something else. Search my videos for no start. They will help you diagnose some other reasons.
