Coach batteries not charging while driving. 2005 Safari Trek
I have just bought a 2005 Safari Trek on w22 workhorse. I noticed that my battery boost switch isn't working when my chassis start battery would not start the coach. I found a blown fuse the the battery boost switch and replaced it but that did not seem to fix it.
Through this process I don't think my coach batteries charge when I'm driving. I have to start generator or shore power.
These problems are most likely related? Help? It's most likely a solenoid or relay but I don't have a wiring diagram or part list. Thanx all for your anticipated help
