Flaky oil press gauge /circuit
Until yesterday, it read 3/4 scale hot on the road and 1/4 scale at idle. Now I'm seeing 1/2-3/4 scale at idle and 3/4 to full scale when driving. RPMs don't matter much. Oil level is good and the needle does drop down with power off.
1. Do I blame the printed circuit or the gauge itself? 2. Can I run a printed circuit for a tach dash w/o the tach (until I get that upgrade done)? Thanks.

Re: Flaky oil press gauge /circuit
The oil pressure guages are mechanical in these trucks. I would check the pressure with another guage. Yes on the printed circuit.

Re: Flaky oil press gauge /circuit
So, I just have oil working against a spring and no power into the gauge at all? I was thinking (without cracking open the manuals) that resistance in the gauge or that chunk of the printed circuit had gotten f'd up somewhere.
If it's purely mechanical, I'll pull the gauge and see what sludge falls out. Thanks.
