Hi guys,

My oil pressure gauge pegs to the high side. Then sometimes it will read just fine. When it is reading it show higher oil pressure with higher engine RPM so I tend to trust it. But have any of you had the pegging issue. I figure electrical short, or faulty gauge. Maybe one of you experienced guys knows of a specific cause.

The guage readings of the oil pressure were really not very accurate and are more an indicator. They had issues with the sensor on the ISC 350 and the like. Some were modified to prevent false alarm and engine shutdown. I had one such. After the second and final modification my readings might as well have been painted on. However, the good news is it worked great after that.

I'll start with replacing the sensor. I still don't understand why sometimes it reads like it should, and sometimes it just pegs. I have watched it go from one condition to the other and it is instantaneous. It makes me suspect an electrical short. Does any one know the range of voltage output that is supposed to be comeing from the sensor. If I knew the expected range, I could put a voltmeter on the signal and see if it is just high, or completely out of range.
