I have an older 99 Fleetwood Elkhorn which had a generator installed, however, the previous owner removed the generator and wired the it for a second battery. However, he did not remove any of the wiring associated with the generator. I replaced the old Magnetek converter with a PD4600. the installation went very easy but it will not charge my batteries and several people have indicated there is something between the shore power and the batteries which is causing the problem. As I have no intention to put a generator onboard I would like to pull the wiring associated with the generator out and rewire the shore power directly to the converter. My number one concern is the Automatic Transfer Switch. As it is used primarily to switch power going to converter when the generator is used, will removing it cause any problems and do I need any special isolators or fuses in place between shore power and the converter? thanks for any advice you can give me.
