RIP my friend, you were a great man and missed.
Kinda got the willies watching how close that wrench was to shorting across terminals.
Nice tip about using lock nuts on the battery terminals.
Love the show
I have to say the nilock nuts are a smart idea. Thanks for the information
Hi on a DF70A Suzuki outboard motor were do I connect my positive and negative wires to the motor side
I just found your channel, I am buying my first used boat and trailer. I am glad u have made these videos simple and easy I need all the help I can get thanks
Deputy Prepper how do you like boating. I just bought mine this past week. 2019 thanksgiving week. Need help connecting a marine battery.
Who makes the screw terminal kit?
Only thing I can say is you always ALWAYS stack terminals from largest to smallest so you're not creating resistance before your larger lugs.
Awesome, thank you! Do they need to be spaced with anything, or can they just sit on top of each other?
@@jamescanady3442 they can sit directly on each other. I would avoid stacking more than 3. Your main ground buss should be attached to a lug on the engine that can handle any amount you can throw at it on a small boat. If you have more to ground you can add a buss block with multiple terminals. move the main ground to the the terminal closest to the ground lug. Your ground path would then be #1: Ground buss to main ground, Battery ground to Ground buss (same terminal is ok) #2: Any other grounds to the terminals next to the main starting with highest draw. Limit to 3 per terminal if you can. Inspect connections on a regular basis to make sure they are tight. Use a conformal coating like liquid electrical tape. Use marine grade wire and shrink wrap for everything. Remember that electrolysis is the result of electrical loops. Bad connections make it worse. Oh.. Use the main battery terminals for you connections to starter / ground. Use the small terminals for power to accessories. Swap out the wing nuts for nylock nuts or a nut a lock washer combo. Only use stainless.
@@ryanskare6670 Why limit three per terminal? I might need to do 4 on my setup.
@@austinwinter4575 You're just trying to reduce the resistance in the connection. It is the AYBC recommendation but if you need to and don't / can't add an additional buss then just follow the terminal size rule of largest/thickest terminals first.
What gauge wire do you use coming from the battery to the fuse box
nice job
This was helpful. fantastic vid and well presented.
Might want to update this. Per BoatUS, AAA, and a few others, Wing Nuts are no longer acceptable to use to retain the wires on the stud. I had to change mine out when they reviewed my boat for insurance.
That tip to use a lock washer or nut is more important that people realize--thanks for stressing it. I use a wing nut, easy for my hands when I don't have a tool handy but I put a lock washer under it; as you say, it will not back out and lose the contact. But here is my problem--I have one battery that has, of course, the major black wire on the negative, and the major red on positive. And the minor black wires of course, also on negative. BUT, there are wires dangling now-for several components. They are NOT black--or red. I can't trace where the other end of the wire goes, so how do I sort if should put them on the red or black post? Related, is it safe to go to the helm and find some component that is not working, then go back and touch one of these wires to the red and see if the component comes on--or will that maybe burn out a fuse? thanks.
I lost the wing nuts. What sizes are they usually? The positive is larger than the negative. 10M and 6M?
He said the sizes in the video. 5/16 and 3/8
Love you x
I'm installing a 6switch panel with switch illumination? How would I wire it so that the panel will not draw power if key is not in ignition.
Daniel Jimenez you would have to find a keyed power source. By keyed i mean the only time the wire or terminal has power to it is when the key is on. You will either have to tap into a known keyed power wire or the switch could have an open terminal. Something to consider though is that you won't want to leave your key on just to run a radio, lights or what have you. I currently have two batteries one for cranking my outboard and one for accessories. that way you don't have to worry about draining your battery and not being able to start your boat.
Brett Tabor do you have the second battery on a circuit with the main battery or do you have it standing alone.
Just wire your switch illumination in parllel, but place it after the switch. That way the switch only illuminates when the switch is on.
You do not want to use wing nuts in a marine application. Also you want to stack starting largest first then work up to smallest. Ultimately you want to use a battery terminal mount fuse block.
I have a boat when I try to start it up on the lake, it starts up then it makes a very loud popping sound then smoke comes out out of the water exhaust can anyone help me? It's an Johnson evenrude 33hp electric start
Could be water in your gas
WERE DO THE CABLE FROM THE STARTER GO ON THE POS/ NEGI / POST
Yes.. red to negative black to positive and wait for the smoke of success and a job, well, done like a steak...
There’s always repair shops for when you cant figure it out and hospitals for when you tried..
I HAVE A 1982 CIMMARRON BOAT THAT IS LIKE HOT WIRED I HAVE TO DISSCONNECT THE WIRE ON THE POST WHEN I STOP NOT TO KILL THE BATTERY
Did you actually hook up the ground first ?
Why would that matter in a boat? In a car I see that it would matter since the entire car is grounded. But in a boat only the negative terminal acts as the ground.
how about hooking up more than a single wire. Attaching one wire to a battery isn't really helpful
You just stack them
ABYC standard State that largest terminals go at the bottom.You stack from largest to smallest. It has to do with resistance of the small terminal on the bottom compared to the top one.. And wing nuts do not belong on a boat.
Lol what the heck did I just watch. Hahaha
Oh wow, that was bad and was actually incorrect on a few things. Like another commenter said, put the main cable (cranking battery cable or trolling motor, etc) on the battery first. Not last. Once you put in on the bottom do the rest of your stack of connections, you can always put a small, dime or nickel sized washer on the very top before screwing the nut down to tighten it all up.
wing nut battery terminals are not acceptable. maybe use them on your rv or trailer home
Bill Clinton , is that you?
Did not show or tell which wires went to where from charger that was the question
TAPE UP YOUR WRENCH.
I like this, but it needed a close up of just the battery and your hands. Bit too far away for some novices to decipher.
DO NOT STACK ACC RING TERMINALS FIRST. BATT CABLES GO ON FIRST IN PROPER STACKING. USE THE POST WITH A TERMINAL OR RUN A TWO GAUGE TO A TERMINAL POST LIKE A BLUE SEA OR SOMETHING SIMILAR. THIS WAY ONLY LARGE TERMINALS ON THREADED POSTS.
Not very helpful for me either.I wwanted some information on how to correctly replace my battery cables
This is mostly bad advice here. Sorry. If you must stack connections on a battery terminal, largest on the bottom and stack like a pyramid, max 4 or 5 as long as your nut can screw down your post with some to spare, BUT stacking is lazy and bad practice anyway. Good practice is to use a terminal block / bus bar instead and have only 1 cable from the battery to the block. Cover the opposite terminal with an insulator before swinging the metal tool around. Don't just eyeball it. Accidently shorting could kill you, start a fire or ruin your battery etc and have a permanent marine cap over the positive terminal. Wing nuts should never be used in a permanent install and would be flagged in a survey.
Why do people make tutorials when everything they say is wrong? Ignorance is bliss I guess
@@FishStalker777 True. Many tutorials are well intentioned and harmless but in this case its straight up dangerous.
where's the bikini babes?
don't they hangout sunbathing on the shoreline?
You shouldn't have soo many connections on the battery stud....run that shit to a bus bar....Wtf guy?
wow, that was a waste of time....looks more like someone pushing products
Sean T NO shit, he WORKS for the company. Way to be observant.
Eric Miles No Shit.......
They're called "threaded studs"... Guess you need someone to edit your script....
Lose the music.
Are you serious? well there goes 4 minutes of my life ill never get back wish i could block youtube channels
3 min video that could of been 30 seconds
Multiple wires at a terminal ENCOURAGE corrosion..... END OF STORY...
Lead In is TOO LONG! Lose it
BAD advice !!! BAD work practice !!!
Useless waste of time
