Serviceman says he thinks a battery disconnect switch is on...but I cant see of find such a thing and cant quite see how...I think when they took out generator to service they changed some

Typically the battery disconnect will be a switch near the door. Mine has a big red light that is lit when the battery is connected. If any of your 12 volt items work, such as lights, the problem is not the disconnect switch.

There probably is a relay on the firewall that connects the battery into the alternator charging circuit. Mine failed which caused your exact problem.

I have attached some docs that will aid in troubleshooting.
