I am trying to find a source for the coach electrical schematics (Rexhall American Clipper, 2004, Ford F53) which particular attention to all the add-on stuff under the dash. I have the Ford schematics, but they don't help with the added isolators, etc.
The issue I'm trying to fix is that I don't seem to have the "charge" control signal to the battery isolator which is causing the engine battery to discharge when we are on shore power (safety sensors seem to be connected to the engine battery) and the house battery bank isn't being charged by the engine when driving. The issue would seem to be the purple wire connected to the isolator, but I haven't been able to find the other end...heck, might not even be the same color.
Any pointers to schematics would be wonderful, but would happily accept any suggestions on were to look for my missing voltage.
