Thanks for the thoughts. Chris wins today’s prize. We got it working again today. It seemed to be the starter button. When I shorted the contacts it worked and after cleaning those contacts, all seems to be well. I am considering replacing that 20 year old switch along with the glow plug button and key switch on that panel. Anything mechanical and exposed like that I presume to have a limited lifetime and those are 30 years old. Dave
