Mopar Gas/Oil/Temp Sensor Simulator
Hey Mike, very generous of you, I am almost there, but thanks anyway. And Redfish, thanks for your input. Yes, the fuel gauge works great, and ammeter also. I had already installed the IVR3 solid state unit in place of the contacts/bi-metal strip in the fuel gauge, which was disabled by bending points apart. With engine running, I quickly grounded out the grey wire which is used at the canister style sender, (new), and saw NO movement at the dash gauge, then held it to ground....nothing. BTW, we installed new wiring front to rear of the vehicle and lightly sanded all contact points on circuit board and other points of contact, in addition I added another ground to the instrument cluster and validated its continuity. Previous owner had completely hacked most of the cars wiring to the point where it would start 'ONLY'. Nothing else worked. We are at over 140 gremlins removed/fixed from this 50 yr old car. I also tested the temp gauge by shorting it's connector to ground briefly, and got movement from THAT gauge. That is likely a wrong sending unit for the rally gauge set-up, I will follow up results here once that sender is changed. So, at this point, I am thinking our oil pressure gauge had been toasted by previous owner likely, so I am going to swap temp senders before I pull the whole dash out again and take a closer look at the OP gauge. I appreciate any input or opinions here......thanks !
