hello all
another cry for help just got the car on the road but the fuel gauge does not work, I have traced the wire back from the tank and it has got an earth to it, the question is does anyone know the colour of the wire to the live feed to the other side of the gauge, it is a three clock dash so all the wires go into a plug with about twelve wires to it as all the clocks are like a circuit board, would look in the manual but its 50 miles away
thanks in advance

hi
ive swoped the wires on the tank and it goes right to the top, my mate at the MOT place said it was working then stopped, he says the wire to the tank is pulsing so that makes me think the live feed is not right
but dont know witch one is the feed, dont want to keep disconecting wires needlesly
thanks

Hi,
It will pulse if it's the old type of regulator (feeds the guages)
If you've swapped the wires and it goes to the top, then the sender unit is 99% going to be the problem, assuming you have a good earth on the black wire.
You can get another sender and just connect it to the wires and test it before pulling the old one out.
Cheers,
Gavin :)

I'm having a problem with mine too. Just got the car on the road and the petrol gauge doesn't work.

However the water temp gauge sometimes goes off the scale at the top, majority of the time its ok though. I've just been to the petrol station and filled the car up, on the way back both the petrol and water temp gauges where off the top of the scale!!

Only me speedo backlight works the other backlights dont!

I thought it might be the voltage stabiliser?

Rich do u have the 3 clock dash ? As mine did this a while ago and it was the plug at the back where it went in to the PCB it move some of the PCB pick ups and all hell broke loose. Just make sure its plugged in correctly and no sitting skew or somethin

Do the later 3 clock dashes have voltage regulators?

Yeah i've got a 3 clock pod, checked the connections on that crappy pcb sheet where the plug connects and it all seems to be ok!

Yeah I did some reading and from what i can tell the older ones, made by Smiths have the voltage stabilisers on the back of the pod. The newer ones made by a jap company have the voltage stabiliser hidden away inside the pod itself!

My mate's got a spare 3 clock pod, the older type which im gonna try. Will help me to determine if its the stabiliser or the sender/associated connections!!

Not sure why the two backlights arent working and the temp gauge goes skitz every now and then but I hope trying the new one will show me where the problemo is!

The earth on the tank? Haynes said its earthed through the numberplate lights and the main earth harness in the boot is a strong one!!

Mind you i did see a spare earth wire floating around with a spade connector on the back not connected to anything, forgot about that i'll go check...

Hi,
there should be a clump of black wires bolted to the rear light IIRC. Crap place for an earth in my opinion.
