vr temp guage problems-help needed

[Duncs_VQ-3800]

Ok so my temp guage isn't working in my series two acclaim anyone able to help?

A first step might be to see if the wire connector is still attached to the temp. sender, on the thermostat housing on the engine.

If it is, you can try connecting a resistor between the temp sender wire and earth an see if the gauge moves. Suitable values for the resistor I don't know off the top of my head. If you want to try that test post back and I'll find out values for you when I can access them. I may in fact have posted them on here before - fuel gauge sender values I definitely have - but can't remember. You can search as easily as I can, more generally outside of this forum also.

If the gauge doesn't work with the sender wire earthed through the resistor, then remove the instrument cluster and look for:

broken tracks on the 'cluster printed circuit board

broken wire coil on the gauge

use a voltmeter to check for power to and from the temp. gauge

Ok thanks ill give it a look

No temp sender on thermostat housing

Hope someone can help??

A few months ago the odometer in my vs series 3 ute stopped ticking over and after asking around i was told it could be a broken cog in the assembly. I pulled it apart, found the cog (missing a tooth) and replaced it, everything was then working fine.

however, just this weekend both the speedo and the odometer stopped working, my digital speed alert also doesn't recognise my speed but it does have power because i can set it (it just doesn't beep like it should).

Can anyone tell me what the problem is?

The temp. sender will be there. V8? On front of the inlet manifold. There are two: one with a blue two pin connector, like an injector plug, for the ECM and adjacent to that is a brass one with a single pin for the gauge. The wire to it is green with a black connector.

I'll post values for the resistor/resistance for the gauge sender when I can access them.

dimo87 you might like to copy and paste into a new thread for your speedo problem.

Na cheap6 she is a v6

OK. Still on the front of the manifold. Follow the top radiator hose back. Both sensors will be behind/under the alternator.

The sender should have the following resistance (in Ohms):

V6
283 cold

56-68 middle

36-44 hot

V8 (for future reference)

283 cold

70-78 middle

37-43 hot

Some combination of $0.40 1/4 Watt resistors will do. Maybe a 39 and a 56 Ohm?

Probably the speed sensor in the gearbox has stopped working or no longer connected (broken wire).
