I know this has been covered before, but I don't recall the answer. I was suffering through the floating temp & gas gauges syndrome and finally replaced the voltage regulator. The temp gauge now max
Simon, This is normal for my car, but if you find an answer, let me know.... Seriously, I have had this problem for about two years and can't trace it. I suspect it is internal cross-talk or groundin
This is an easy one! Just reverse the wires on the instrument regulator and it will be fine. Not related to this problem, but just as a heads up, make sure that the case of the regulator is grounded
FWIW, that didn't do it for my gauges. I was getting the pulsed 7V average output, but reversing the regulator leads turned it from a "rise-to-1/4-then-fall" gauge to "no indication at all" gauge. -
