Well here is an update. Took a quick look at my sender tonight and found it is kinda hard to reach without getting
into it more than the daylight allowed so I gave it a little tug and wiggle and said that's it until I have more time.
Fired the beast up to put it to bed for the night and (hummmm ???????) the oil light seemed to work correctly.
I tried it several more times and the light is working perfectly. I DON'T GET IT!!!!! Oh well I'll try it again tomorrow.
