help me find an electrical gremlin, please
One will work on both and only one will work with the five pin. I can't remember which way it is. Do you have a two prong ballast or four prong.
If two prong then I think the four will work. If four pin then I think you need the five pin.
Maybe Del will confirm.
I am still curious why you have no AC voltage coming from the pickup. In the past I have read on here that some have gone through two or three before they got a good one.
