A couple of days ago I installed the Progressive Dynamic’s 4645V 45 Amp Converter/Charger Upgrade, and subsequently further researched the installation and realize I made a mistake. Also, several online sources suggested that a converter/charger upgrade warrants an upgrade of the wiring gauge leading from the charger to the batteries via the low-voltage disconnect (LVD) device. So I pulled the entire install out and checked the wiring. It appears that one of the previous owners cut the factory wiring and installed new wiring with a shortcut that led out the back of the cabinet and along the driver-side wall behind the now-removed couch to the LVD. They spliced the new wire to the old wire just prior to the connection at the charger fuse panel. I don’t quite understand why they just didn’t attach the new wire directly to the fuse panel? Also, the new wire runs directly over the hot water heater and isn’t tied down at any point. Do you really want a wire sitting on the hot water heater? It just seems like a fairly shoddy job. I will need to correct this by protecting the wire and terminating it directly to the fuse panel.
I reinstalled the converter/charger upgrade correct this time.
I removed the old batteries and set the two (2) new Lifeline GPL-31XT Deep Cycle 125 Amp AGM Batteries in the battery tray, and they fit! While I was pretty sure how the wiring was originally configured on the old batteries (I should have taken a picture), I did some quick research to make sure that I reconnected the wires appropriately. The good news is that the 12 V system began working right away as evidenced by the lights coming on inside.
I plugged the Chinook back into shore power and made sure I had a fire extinguisher nearby. All systems appear to be working – I tested the 120 V system using one of the outlets. The converter/charger was blinking a green light indicating that it was in “boost” mode and charging the batteries. Nice work!
Using my multimeter I tested the voltage at the converter/charger fuse panel (13.58 V) and at the low-voltage disconnect (13.45 bolts) resulting in a net loss of 0.13 V, or 1% voltage drop over that wire run.
