I have a 2002 HR Navigator 40 PBT. My chassis batteries are not charging from any source, sources include shore power, generator, solar panels or alternator when driving. ( the house batteries are being charged by the inverter charging system with the generator running and also on shore power) Any help would be appreciated I have searched and not really having any luck. The boost relay does work as that's how i got the MH home last night, by using that intermittently as I drove home yesterday approximately 600 miles.
