I ran it around the block and have checked it twice in the sight glass. Guess I just assumed i couldn't be right. Anywho, the oil light does not come on at all. Not even during start up. I believe there is a ground switch that can go bad with those things is that true? I went out on me when i switched over to LED's, now I get nothing out of it even after i put the old bulbs in. All the other lights took to the LEDs fine.
