To shorten a long story my alternator went out after being jump started at a windshield repair shot. They kept it longer than planned and the voltage dropped low taking out the alternator. It could have been plugged in to charge the batteries, but wasn't. In a attempt to fix it the tech got the wrong alternator and also Wired it up backwards. This took out the 12 volt charge wire that had to be replaced as it grounded it and melted the wire. It also took out the 12 volt ignition wire, as there is no longer 12 volts on it.
To get the coach going I found a relay That had a switched 12 volt spare terminal and ran a new wire to the new/correct alternator. The motorhome now charges as before but if possible I would like to return it to the stock confuguration.
So does anyone know where the white wire that goes to the alternator ignition terminal start at? Is it fused anywhere? I have looked over the wiring diagrams but haven't been able to find what where it might be, but my computer doesn't let me enlarge them enough to see everything.
Thanks for any help. I know it is fixed now, but would like to fix it better.
