Finally got my water temp gauge problem worked out(bad sender),now it appears my
oil pressure gauge is malfuntioning.It has read 50-60 lbs from the beginning and today it will not budge from 25 lbs,with switch on or off.Any thoughts?AlsoI got rid of my ammeter and bought a voltmeter(SW).On the back one post is labled with a +, the other post labled with a I. I thought one should be negative- and the other positive +.In my mind the I would stand for ignition and assumed to be the positive hot wire.What gives? chuck
