Goofy me. The alternator is dry, it is the starter that it drifts on.
Guess I'll have to degrease and look.
I assume the oil sender is up where the oil filter is, which means I need two extra elbows and a wrist to get to it. Will work on the pix, but probably after degreasing.
Oh! Is the oil pressure sender done through a PVC type tube? The AZ sun does tend to really bake things.
