Hello again,Trying to troubleshoot my (1982) gas gauage not working properly, I've narrowed it down to probably my sending unit but in my testing of various things, I came across a few puzzling issues.
1. There are 3 studs on fuel gauage: Power, Ohms, Ground. Power is good, ground is good but when I turn on the ignition, the ground continuity goes away??? With the key off, the ground has continuity with the Chassis. The ohms wire has continuity to the gauage also.
2. Testing the Pigtail connection at the tank. If I unplug it and test the 3 wires going into the tank, the power wire for the pump has continuity with the ground. That doesn't make any sense to me???
So, I'm trying to keep from pulling the sending unit, until I know it's what's bad.....Any ideas on this?
