Stumped

First, what sort of problems are you having? Does it read high, or low, or intermittent?

Are you sure the temp gauge is OK?

(The voltage limiter affects both.)

You CAN check the gauge for accuracy. Mopar used to have a test box you could hook in place of the sender, but if you have the sender out, you can ADJUST the sender to these resistances, and then see if the gauge reads accordingly. Alternately, you can get some "power resistors" at Radio Sh&& and substitute them in place of the sender


The values are:

L = 73.7 Ohms (empty)
M = 23.0 Ohms (1/2)
H = 10.2 Ohms (full)
