Re: 2 out of 3 FIXED, 3rd a bit Surprising.

This is an actual gauge output, not the idiot light. I measured the sensor output at the closest connector between GRN and BLK and got 147mV when it was up to operationg temperature. With only that connector disconnected I get 12v on the other side of the connector between GRN and ground. That same voltage is of course on B3 and on M on the Insturment cluster. When I disconnect that connector on the cluster the 12v goes away from M and from B3.

I cannot find a direct short to wire M on the cluster itself and any other contact on either connector. It seemingly only connects directly to the gauge. With the connectors connected, but not powered up, I cannot find a short to any other point either.
