Suspected Converter Problem
Hey guys, back again. Hoping to gain some insight into an ongoing problem we've had this summer. RV is a 2004 Fleetwood Terry Quantum AX6 365FLTS. The rv came with a factory installed WFCO 8855 ...

Okay guys, update.
Fiddled with it just now. The loose connection was the issue. I hooked up a battery and was reading almost identical voltages at the converter and battery terminals. Hooray.
Now for the bad news. Over the next ten minutes, voltage at the battery terminals slowly began dropping. By the time I walked away, it was down to 13.7v.
The voltage at the converter stayed constant at 14.4X the whole time. I felt the battery cables and they are heating up. I suspect excessive resistance due to undersized cables (8 AWG).
Do you concur with my suspicion? What size cable would you recommend? Again, I have ancor marine grade 4 AWG laying around.
That should not be happening with #8 which is fine with 55 amps at 3 feet of wire. (6 feet total circuit) I suspect your terminals are corroded. Yes, replace the wire. If you ever did the jumper cable trick I mentioned before, you would have an independent test of converter to battery vs the existing wiring.
On PD with CW vs a PowerMax LK there is no comparison. The PD has only three voltage choices and limited times for each, while the LK is totally flexible for voltage choice and how long to stay at each voltage (that is with the adjustable mode--with the fixed three-stage mode who cares? never use that.)
BTW there are several forum members with PowerMax converters of one model or another. There are also many members with PDs. Some even have Iotas if you can believe that! :) It used to be a Ford vs Chev kind of thing, but the LK is such a game-changer with the adjustable voltage mode, it is now more like sail vs steam for ships.
