Ok Guys, My fuel gage only works with the park/headlamps on. I've checked the circuit on the sender side, good ground & continuity up to the gauge. I've got battery voltage at the gauge.
Pink wire is batt., tan wire is the sender. With the test results I have gathered, the gauge should work. But, It only reads accurately when the lights are switched on. Now, I thought I was fairly knowledgeable when it came to electrical, I can fix 30k $ Caddy's all weak long. But, this one has got me baffled. Anyone have this problem before?? Thanks in advance.
