Rally dash oil pressure gauge issue.

Dartswinger70 said

Currently this is what I have going on, the oil and fuel guages dont work, the temp and ammeter work. I cleaned all the contacts on the printed circuit board,cleaned the bulkhead connector and put the das back together, I did see that my brake warning light pulsates kindof liek the 5v oil sender pulsation, i dont thingk its from the turn signal flasher. So more issues to contend with. iam ablut ready to order mew guages and PC boards,getting tired of taking this thin g apart and ptuuing it bacl together.

You may have missed 1 electrical contact. Because the limiter is inside the fuel gauge that gauge can has a slither of metal on its backside that grounds it to the inst' housing. I don't know if that is your problem.
I know faulty limiters do strange things at gauges, and since it is on the same 12 volt supply as the system voltage regulator a fault in the limiter could effect that regulators operation. So the pulse you see at brake warning lamp could be present throughout the cars electrical.
I agree this rally panel is a chore to R&R. I won't put one back in until I've installed a solid state IVR, a ground wire, all new light bulbs, everything I can do, and bench tested everything. Then if it doesn't preform in the car, I know the fault is in the car.
