I had to order a new power supply and replace the WFCO 8955when after a few months of dealing with the cooling fan not working due to poor connection. I kept lights on by swapping batteries after charging them with an external battery charger each day.
I chose a Powermax PM4 75amp cassette for about $160 (Amazon). I received the package was just the power supply in a box no packing material or instructions.
The wiring was easy to figure out 120 v hot, neutral and a ground. I had to drill a hole between the plastic under DC fuse holder due to shorter wires on DC side. Positive wire was blue.
Tighten all the connections and now have 13.75 V and up to 75 amps as needed. Lights, battery charges properly and the heater fan kicks in without even causing lights to flicker. The New power converter seems slightly louder than the old one but I know its working.
