disconnects all 12v power from battery/ batteries to trailer.
TURBS
Thanks, so I should put that in when plugged into shore power? That has any effect of the charging of the battery? Sorry for the stupid questions but my grandfathers camper didn't have this feature and he wasn't sure what it was either.
more than likely it will not charge battery when plugged in to shore power unless key is in and turned .
to find out plug in shore power cord and take a multimeter and check battery voltage.
should be around 13+ volts or so .
not a stupid question at all.
