I have a model 3 with a 912ul and a westack 4 in 1 meter that reads EGT, Water Temp, Oil Temp and Oil Pressure.

I was getting to go for a ride today, and when I turned on the master switch, the oil pressure indicator pegged high. All other reading were as expected.

Turning off the master drops it back to zero. I disconnected the connector from the sender, and it still pegged high with power on, and zero with power off.

Anybody got any ideas???
