My SC has always had good oil pressure, just under 1 bar at idle when hot, pretty close to one bar per 1000 rpm.
Last week it stopped regigstering completely. After the panic settled down I found the problem, the sender wire was damaged about 6" from the sender in a couple places. I'm officially blaming it on the PO, don't ask
Anywho, I spliced in a new section of wire about 4" long using automotive electrical cripling thingies (technical term) and sealed them with electrical tape.
Everything is now fine except at idle when warm the gauge shows less that 1/2 bar. It looks like the gauge is reading about 1/2 bar lower throughout the rpm range than it did before. The oil pressure light does not come on at all when the engine is running but does work when the engine is shut off and the ignition is on.
Could the lower readings be caused by increased resistance from the crimping connections or additional 4" of wire length? does the gauge read lower with increased resistance?
BTW I'm pretty good with mechanical stuff but electrically challenged. TIA.
