There has been much written here about the temp guage and the "temperature compensator board". I have an '89 that exhibits this guage problem, actually since it was new. I have Volvo-published wiring diagrams for this year and model. Now I'll admit that I didn't survive EE at Georgia Tech, but I know enough about reading a DC schematic to see that there is no such thing as a "compensator board" on THIS car, but there is a "voltage stabilizer" or regulator plugged into the back of the IC. Could this be my problem? I see no other component between the temp sender and the guage.

I called RPR yesterday to order a stabilizer. They instead steered me to the compensator. I questioned whether it was really on the '89 model, and they replied "yes", the car has both, and referred me to Bentley (which I don't have). I declined to place an order.

Can someone please cut thru the fog and give me the poop on the '89? If I'm going to purchase a part, I want the right one, since electricals are non-returnable.
