Hello all - we just purchased our 1977 31' Sovereign
and I'm trying to get the electrical system back up and running...
When we purchased it the Univolt & Battery had already been removed, so I bought a new battery and a Progressive Dynamics (PD9260CV) 60 Amp Power Converter with Charge Wizard.
I followed the AS's service manual schematic and hooked up the battery and the converter, running cable from the converter to the specified spots on the fuse box. I then plugged the AS in, and tested the converter, cycling through the 3 modes and testing the output. All worked great!
So then I unplugged the AS, went back in and tried using the 12v
lights and nothing would work. I had to actually remove the copper wires connecting the converter to the fuse box to get the 12v
system to work again!? Had I done something wrong? My understanding is that the converter should charge the battery when the AS is plugged into 120, but when unplugged the battery should still power the 12v
system without having to do anything.
Am I mistaken? And bare with me if I'm doing something obviously wrong - this is our first Airstream, let alone our first camper period!
Thanks in advance!
