THE BITCH IS LIENG TO ME!!!!!!! :mad:

hmmm,may be some grund trouble....../Per

Now, now DT! She wasn't lieing. You didn't listen! She said your interior lights were hot. Maybe if you had a US system you would understand better?

Detom,
try this

maybe this will help!!

LOL, good stuff.

hey, it's as good as most wiring diagrams I've seen for our cars.

Thanks Ed. I like mazes.

It is definetly an electrical thing. I can turn on about any switch and drop my engine temp. Actualy the car is running cool as a cucumber. It doesn't even tink after driving it. You know how a car goes, tink, tink, tink, after you shut it off and it has gotten hot??? Well she don't even do that. I bet she is at operating temp and that is all the hotter she is getting.

I've had the same symptoms a 1970s UK car (Lucas Wiring) when the instrument voltage stabilizer failed.

This was a small metal unit that looked just like a flasher unit (and worked on the same bimetal strip principle) See the picture.

I don't have a Pantera wiring diagram to hand - but I assume it must have one of these somewhere in the instrument wiring.

Detom, does the temperature appear to drop if the engine speed drops below the point where the alternator stops charging?

No that doesn't seem to do it, it is only when I turn on another accesory, and then it it just drops to what I am thinking is a true reading. I am betting that a resistor is going out, and that failure mode is the least common. Usualy when a resistor goes out it goes straight to an open circuit, which would be a zero reading at all times. I have seen this a few times in my career as an engineer where the resistor will only partialy fail, but it is rare as hens teeth.
I don't know if I really want to tear into this problem or not. I can tell for certain it isn't really overheating. It may just be something I will live with until I restore the car at which time I am going all new harness anyway. It just goes to re-enforce my feelings about the accuracy of 30+ year old gauges. They are mearly friendly suggestions and not true indicators.
