Solution to Sticky fuel/temp guages

Removing VP gauges/speedo to fix dry solder join voltage regulator 3 pin

I just realised that on my tacho dash, all i did was remove the clear plastic front and surround. Then i undid the 3 nuts holding the tacho in place and removed the tacho. Then i took out the small circuit board at the back and thats where the voltage regulator was. Resoldered that and replaced all parts and it worked. I never had to touch the needles on any of the gauges. I wonder if its different with non tacho dashes?

See my recent post VP Instrument Upgrade - Low Fuel Light / Trip Computer for a photo of the voltage regulator.:wave:

Same for non-tacho dashes.

I've taken out the speedo by removing a few screws from the back & unplugging the flat connector. Don't work from the front by removing the small screws on the front/indicator needles.:bang:

my fuel guage needle has stopped responding and ever since, the battery warning lamp is lit. What is even more perplexing, the lamp is quite bright during daylight motoring but then seems to dim somewhat during the night.

The needle miraculously worked on one occassion and the batt lamp was out. Next trip however, needle dead and lamp again on.
I've had a bit of a poke around the fuel tank end with the multimeter and couldn't find a fault so what do you blokes reckon? Rip the dash apart and give it a squirt or maybe the sender is cactus??
Any help, much appreciated.

Oh, the trip and odometer have given up the ghost.

The long term side-effects of the dash bash I suspect.

Dead dash - do you think you had the faulty voltage regulator with dry joint?

You might need to resolder that.

mine fuel gauge moves up and down as im driving, will this thred make my fuel gauge stay in one stop while im driving?

both my fuel and temp where sticking, i was a regular dash basher.

the thing was, put a half a tank of fuel in and it would work fine... but once it got below a 1/4 it never showed anything - unless i bashed it.

it turns out that the voltage regulator was fine... the 2 contacts on the flex which connected to the plug where oxidized (a visible black layer on the copper strip) and wouldnt conduct at low voltage.

thanks for the post though... made it easier to pull it out and check it.

Hmmm does this work with the speedo sensers aswell? cause mine get sticky

when i stop the car, it usually sits on 20km/h haha.... also it gets a bit sticky at around 80-90km/h, jolts then shoots up to 110km/h

any suggestions?

G'day all
just finished fitting a tacho dash to a vn wagon and found tacho sticking. Pulled cluster apart and found tacho needle moving freely. Reinstall and started sticking again but what is confusing me is the standard dash i took out the fuel gauge (where the tacho now is) also used to stick. Any ideas would be great. Cheers.
