Coach Battery not charging from motor generator. Transfer relay in Coach Battery compartment not being energized when key is on. If i jumper from caosch battery to relay, it energizes and rear battery chages. Also rear wiper / defroster do not work - but when I energize relay they do.
It appears that ignition-on voltage to rear wiper / defroster ot present, but with relay picked, voltage is fed through fuse to bus for rear things.
I want to get to the relay under dash that is picked when the ignition is turned on. I can see it and touch it, but can not get clean access.
