[V-SLR5000-P]

My SLR5000 has not had temp or oil pressure guages working since l aquired it. No problem, its an unregisterd project. But on the weekend l thought l would try to get them working, problems are as follows:
TEMP; needle does not move when the guage is earthed, shouldn't it read full hot?
OIL; ignition on guage slowly climbs to maximum, start engine guage slowly falls back to zero. l have tried a couple of senders and a mechanicl guage confirms oil pressure is OK.
Is this the voltage regulator at the rear of the instrument panel??
Tacho, volts and fuel are fine.

Your temp gauge may be burned out, and the oil pressure sender unit (on the engine) might be an LC/LJ one instead of an LX one - the LC ones work in reverse to the LH ones, and will cause the problem you have described. Oh, it is an oil pressure sender unit (big round can), and not just a warning switch (smaller plastic can), isn't it?

If the voltage regulator is faulty, it will affect (and eventually cook) all three sensor gauges, ie fuel, oil and temp. It doesn't affect the volt meter gauge, as this is fed battery voltage (obviously), not regulated voltage.
