86 GMC Oil Pressure Gauge Issue - The 1947 - Present Chevrolet & GMC Truck Message Board Network

fast72beeper · 09-18-2012, 12:18 AM

Putting the finishing touches on a 86 GMC Im putting together for my sis in law. But, Ive ran into an issue with the oil pressure gauge.

Right now I have a mechanical gauge installed as I’ll be breaking in a new cam and want to make sure on the pressure.

The stock gauge pegs when you turn the key on. If I ground the sender wire the gauge goes to zero. Is that correct? If not, where to look, check, etc to fix it.

Thanks for any help
