My fellow friends. The trying to be a troubleshooter is back. Haven't give up yet but close. Sitting for a month with shore power, will crank but will not stay running unless i press and hold the battery switch. I have replaced both batteries, generator, fuel pump. Two switches inside entrance suppose to light when things work normal one lights the other don't. ANY ADVICE WILL BE APPRECIATED. I do own and know how to use a Volt Meter.
