Pure entertainment today. From the exploding building to the wild speedo needle. Great video!
Thanks mate!
Some years ago I repaired my fuel gauge, had to change 2 capacitors, so now it's working.
I have also repaired my odometer? don't know the right name of it but it's the one that show how many kilometers you have driven. The fault was a small spur gear made of some rubber/plastic that had lost a couple of teeths. Today I helped my neighbour with his 1998 Volvo 945. Changed the speed sensor located at the rear axle because the ABS-lamp was on but the speedometer was still working. The sensor was faulty, high resistans. After that I cleared the fault code and the ABS-lamp is now off. Thanks for your Volvo videos and keep the coming!
Ah yeah, I recently did the same repair to the odometer on the 240, luckily those gears are easily available. That's good to know, I have an ABS light on the 740 and no speedometer so perhaps the sensor is at fault also
@@Involvod You can measure the resistans of the speedo sensor in the rear axle with a multimeter. It shall be around 800-900 ohms if it's ok. The sensor can be a hassle to remove though.
I had to remove the rear axle cover om my neighbours Volvo to remove the sensor from inside to out and then put new oil in. Oh and there is no gasket between the cover and the final gear assembly. You must use some good packing adhesives. The front ABS-sensors should have a resistanse of around 1000 ohms if they are ok. Take care and I wish you good luck. :)
@@tompas11A3n52KkX thanks for the info that's really helpful! I'll take some readings
I have 1 unserviceable fuel gauge taken from volvo 940 GL. Do you have guidance to find which component need to be replaced?
@@peterelias2345 Whitout proper instruments för testing capacitors it's hard to tell if a capacitor gone bad. Sometimes electrolytic capacitors become swollen and that is a sure sign of a bad capacitor. Otherwise you must measure the capacitor to know if it is bad or not. I have a capacitance meter and an ESR-meter for checking capacitors. Often you must desolder the cap to get a correct reading.
Good evening Sledge, nice speedo repair, its always good to know how fast ur going, be safe my friend!🙂
Thanks man!!
You gave me a heart attach Sledge - exploding buildings indeed! Glad you got Sylvia's speedo sorted out. Onwards & upwards.
😄 Thanks!
Nice one! Wow, the corrosion on this is quite something! So good you figured it out and big props for calibration procedure 🤣. Cheers!
Haha, cheers mate!
love your vids from NYC!
Thanks!!
We have a guy here in sweden that restore the clusters. he tack only 1500 swedish krones for the repair. and he also sell repaired clusters
Thanks for the info, that's alot cheaper than a used unit here! Even postage both ways included!
1:17… she’s factree… pretend we didn’t see that 😜 great video fella. Had two clusters go on my 740s lol
Haha, it's pretty much guaranteed at some point isn't it!
Oh I know that feeling. Upon purchase of my 92 740, the only gauge on the cluster that worked properly was the tach. The speedo was particularly bad, spazzing all over the place constantly (and I think mine has the VDO gauges, so I’d say they all have issues).
Is there nobody in Germany that offers cluster repair? There’s a place down the road from me here in the US that repaired everything for a flat fee… not cheap, I wanna say about $200, but it sure was nice to get it back and everything worked perfectly.
Wow that's expensive, but still more cost effective than buying replacement units that won't last 5 minutes..
The smacking of the dash is a daily ritual every time I drive my 745t 😂 My fuel & temp gauge stick plus my tach jumps around. I have a very nice low mileage cluster out of my wrecked 744t that I salvaged from it before I sent it to redblock heaven that I might install eventually.
What causes that again? Someone with a 740 told me they have the same problem, their fuel and temp gauge needs a tap. I have the same issue on the 240 speedo
@@Involvod not sure but my 745t sat for 15 years with the sunroof partially open before I saved it so I'm sure that didn't help. It was worse but I took my cluster out and tightened up all the screws on the back of it since most of them are part of the circuit. It definitely helped and the cluster functions much better now.
I wondered where the black goo from Spiderman 3 ended up 😂 good fix with the speedo, they always over read instead of under read... Sorted!
Haha, cheers!
Nice to know the cluster is fixed
That redblock sounds soothing, makes me look forward to owning my own 940! just upgraded to GL on patreon too!
It's gonna be a great day! Thanks man I really appreciate it 👍
Still a great rescue, I love that car! 😉
I know you’ll have those gauges sorted soon!
Thanks mate!
Supervideo, so nice to see Sylvia getting better and better! That black goo is all too familiar here; you can get it everywhere when wrestling cable with that tape or from that black water barrier caulking which either sticks to everything or won't stick where it's supposed to ;-)
Glad it's not just on my car 😅
@@Involvod Definitely not ;-)
Here is how to replace those leaky capacitors: czcams.com/video/-xMldQiL7Yc/video.html
Thanks for the link!
If you need spare parts, look for them in Sweden. They have a huge market for used Volvo parts.
Thanks! I need to start looking at the pages
The Speedometer on my Volvo 1988 240 wagon does not work so I’m gonna try this and hope it works!
1st comment!!! ! If it was indeed a race….I won ! Thumbs up already as bound to be good…….as always
Haha thanks mate 👍
What's the fun in DIY repairs without the old roller-coaster of emotions, eh? At least you've got got it working properly again. +5 K's on the speedo feels about right for a stock-ish setting.
Manufacturers are actually mandated to let the speedo read a bit high to allow the owners some wiggle room with wheel & tire combinations without having the speedo read too low.
😄 That's what I thought too. And true, might come in handy if I find a set of Hydras for her 🤔
@@Involvod Yeah, Hydras would fit her wheely nicely.
Sorry.. I'll see myself out :D
5 kilometers is a normal gab. Almost every car has it👍👍
Thanks mate!
I have 940 GL 1994 non turbo. The fuel gauge is not working. I am going to replace the complete instrument. Kindly inform the seller in UK for my reference. Thanks in advance mate
Have same problem, waste of money buying from breakers,they don't last long either,im on my 3rd and that broken now.🙄
That's what I'm worried about! We'll see how long this one lasts...
The Turbo and non turbo cars have different rear axle ratios, I believe. That's reason why the speedo isn't showing the correct speed.
Rear axle ratio doesn't matter, the wheels are always rotating the same speed no matter what ratio there are. Only the wheel diameter affects on speedometer.
I thought you fixed it up or was it something different?
Last time I only managed to get the lights working, now we've got the full package!
Are we changing the capacitors ?
Those leaked and corroded the IC chip.
No we're not, that's way out of my league, you can do them for me if you like 😃
@@Involvod I am shure you can do this. I’m to far from you. Just desolder the two blue wires from the micro switch. Get a good solder puller. Put the solder iron on the cap coenction until it gets loose. Remember that is a doble board. This means that is solder at top and the bottom at the same time. Put a lot of heat and move the cap until it comes loose. Don’t pull it hard you can damage the board. After they are out use the solder puller to clean the holes. These capacitors have a positive and a negative. Install them correctly or the will boow up (ask me how i know). It sounds bad but really is easy. Practice on some other board. A TV board or another.
Best of luck!
@@gannicus1251 thanks for the info!
@@Involvod Did mine today....... I’ll test it tomorrow. What I found. 47mf to 25 volts blown away ( no leakage on that one it just blew up) changed the other 3. Those where so bad that the legs of 2 caps broke off from the caps. So yaeh me test that tomorrow and i will let you know. Ohh the needle to stay in place i had to pull it up pass it over the stop thingi to know where to put the needle to it back together. I put the needle bac at the position mark and pull it up over the stop thingi.
@@gannicus1251 ah thanks mate that's very helpful!
Please say you replaced the capacitors too? If not they'll continue leaking and eventually kill it
Sadly not, it's way out of my skillset/toolset, I thought about sending it off for repair, apparently those capacitors are tricky to find now?
@@Involvod have faith, I've seen you sort of solder on an older video and I think you could do it. The exact ones may not be available, but there will be a 99.99% chance of there being a modern equivalent
@@Adamborland77 thanks for the vote of confidence!!
Volvo clusters....the utterly infuriating issue that is enough to make you get a ford..nah...Volvo forever
Haha you couldn't gift me a ford 😄
Dean of Machines unboxing was sad, no respect for shipping peoples property.
Yeah I don't know how they throw things around and still sleep!
