Battery charging


New Member
I am trying to figure out why my seven pin trailer hook up will not charge my batteries on my 2016 ice cabin fish house There is power to the plug on my truck 14+ volte But as soon as I plug it into my Fishhouse it’s like it cancels it out the voltage on battery’s of fish house don’t move up at all I’ve ran clips from the -and+ 7 pin on my truck to camper batter still nothing battery volt stays the sameIs it just that slow of a charging system
