I believe my coil is bad on my Onan 4BGE generator

I hear ya, David. I tried working on this thing "in place" for a while but even pivoted down it is hard for me to get on my knees and work on the thing. It was so much easier pulling the unit out to work on it. It was not as bad to pull out as I thought. But I wish these things were designed to be removable or accessible a bit better than they are.

Ideally, I'd like to see them on rails so that the entire genset can slide in and out of the compartment.
