Hi all.

My temp gauge is not working properly and only climb to half distance between cold and middle. I have grounded the cable and it climbs all the way to the top. So I’m thinking it’s the voltage stabiliser. I have the 3 clock setup (Cooper) in the picture but I do now that the volt. Stabiliser is printed onto the board behind. I have read in another post that you can solder a solid state voltage stabiliser onto the printed circuit. Anyone done it ? Any guidance would be really helpful.

Thanks

I would start by checking either the thermostatic isn't stuck open (indicated by the engine taking a while to get to temperature) or the temperature sender unit isn't faulty. I would have thought the voltage stabiliser takes care of fuel gauge as well and that would be playing up.

I did this little 'mod' to fix our mpi fuel/temp gauge error.

Can you describe what your issues were before this fix? I'm seeing what appears to be low temp readings but fuel gauge seems ok. If the regulator was bad wouldn't both gauges have problems?

If the voltage stabiliser was bad both gauges would be out. Get a thermometer and verify the guage, then check what temperature thermostat is fitted, my guess is a 74° currently

yes in my case both gauges were 'out' ...

Sounds like good checks to do. My dash temp gauge has non numeric scale...roughly at what temp should the first & middle scale marks above the blue mark be at?

Also, can the thermostat be checked without having to drain coolant?

When the engine is cold you can check the thermostat. Just run the engine and keep checking the radiator top hose, it should stay cool as the engine heats up. Then if the thermostat is working correctly it should open once the engine is at normal temp, and the hose should start to get hot. If it all heats up at the same rate, thermostat is likely stuck open.
