Coach - National '05 Sea Breeze on Workhorse
Background: House batteries were not charging while driving. Repair shop said batteries hooked up wrong. (I don't see how they could, as I've never had both sets of batteries disconnected at the same time.) If my memory is right, there were two red wires on house and one on chasie.
Well, they moved the smaller red wire to the chasie battery. Now house batteries charge, in fact way way high. In the past they have charged to 14.3 (on a digital volt meter) and now they are charging at 15.8 (Yes I know the high voltage is bad, but need to correct wiring first.)
I think maybe my diode bridge burned out (for some reason) so when the house batteries would not charge the repair shop fix was moved what might be the charging cable. (I think the batteries are now hooked up parallel.)
First question, typically how many positive wires go to which batteries?
I don't know if diode bridges are used, but I don't see how two sets of batteries can be charged without one, so does anyone know where their diode bridge is locted on your coach? I thought it would be in the inverter area, and it isn't. Looked around engine area without much luck.
Third question (I think) what is a "high voltage" when driving? Prior to replacement of instrument cluster (new one does not have a built in volt meter) once up and running, I always had 14.3 volts. Why would I show 15.8 volts on the house circuit when driving. Bad alternator? bad regulator in alternator? bad diode bridge?
Would appreciate the assistance.
