Could be they're not getting a good connection.
Think that's what's wrong with the ones on my car. Oil reads high and Temp reads low.
Matthon is selling some used ones fwiw.
Yes oil is always at H with, or without key in. Seems like it might move a smudge though, with the key on.
Temp is always at low no matter how long the engine is on.
John is coming back out in a few weeks. He said we'll pull the dash face off and figure it out.
I thought I'd be ready with a couple new gauges in case they are needed.
If I don't use them I can either save them or sell them at Carlisle.
