Gauge grounds, where are they?
After all the work I've put into fixing my high oil pressure, and things being a lot better then they used to be, there is a chance, the leftover symptoms I still experience may be just the gauge. I notice while idling, the gauge will peg when the fans turn on usually, and when they go off, it comes down to like 4 bar. I would like to check the grounds before I continue on this exausting crusade for narmal oil pressure. Can anyone tell me where the grounds are for the gauges?
The gauge seems to peg only between 900-1600 RPM. Since I idle at 900 rpm, it likes to peg at idle, but if i bring the RPM down to 800 or so, its down below 4 or 5 bar.

I believe they're the ones on the inside of the firewall directly under the fuse box. It's a bit uncomfortable doing that job.
By the way, I solved my oil pressure guage problems by following a procedure I found on the Pelican Parts technical articles web page. It involves pulling the guage cluster and cleaning the contacts on the guage grounds on the cluster itself with metal polish. I'd tried everything else I could think of and was making up my mind to send the cluster off for service. I didn't think cleaning those contacts could possible make a difference, but I did it anyway. Voila! Oil pressure. It also fixed my spasmodic fuel guage. FYI.

hey thanks a lot for the link. If I find the grounds under the fuse box, i'll clean em and tighten em, then I'll pull the gauge cluster this weekend and do what that article says. Does anyone have a link to that old writeup on how to revive the lighting on the cluster, may be worth doing while I'm in there, though the lighing of the gauges on my car is actually very reasonable. How many (and what) bulbs do i need to buy, might as well replace em while its out.

I pulled the grounds, cleaned em and tightened em back on, it did nothing. I'll try the contacts this weekend. I think maybe the OPRV i have in there is not that good ether. it may be time for a new one.
