WFC 8955AN converter issues?

thanks everyone for the advise and comments. I purchased a powermax 55amp converter out of Indiana. i figured it was a good deal at $125.00US with free shipping to Sumas, WA.(i live in Canada)
I tried to purchase one here in Canada but the dealers wanted between $350.00-$400.00 for it.
The only problem i had was i needed to cut 3/4" off the metal mounting plate so it would slide into the existing slots.
Other than that, a 5 minute install and now i am getting the output required to keep the batteries charged, and the lights are quite a bit brighter. I didn't realize how much a difference it would make.

I switched my WFCO out for the power mad when my trailer was new. It works better than a new WFCO

smkettner,
thanks for the heads up on the preferences on the picture setting!!!!

thanks for all the info. The 10 VDC reading was at the battery connectors, not attached to the batteries(batteries disconectd). it was also the same at the self resetting fuses by the batteries.
i removed the main board to inspect it. not sure if the fan is coming on as the two white heat sinks are "blistering hot" and is browning the board. still only read 10.06dc going out after turning on all lights, furnace and tv (plugged into 12v socket)

Just need to replace what is called the main board assembly. NOT the whole breaker fuse panel. Once you get the face plate off it is just two screws and it slides out.

The smaller 45 amp is fine unless you have more than two batteries or some large 12 volt load like tank heaters.

I changed my WF8955 converter unit out for a Progressive Dynamic PD9260C unit. It fit in the same lower compartment of the WFCO 8900 series Power Distribution Center. You DO NOT have to change the whole chassis out - just the bottom converter/charger unit. The top section containing the AC Circuit breakers and DC fuses does not have to be removed. Contact RANDY at BESTCONVERTERs at the link in the above message. Tell him you want to just replace the converter/charger unit and you want to keep the WF 8900 series Power Distribution unit.

If your WFCO 8900 series Power Distribution unit is getting 120VAC then the WF8955AN Converter/Charger module will always put out 13.6VC. The 10VDC you was reading is coming from your connected battery telling you all of the wiring and in-line fuses between the Battery and converter/charger unit is good. Your converter/charger unit is NOT producing the 13.6VDC when connected to shore power (120VAC).

smkettner,
thanks for the input.... just what i was thinking. Batteries are on home charger as wee speak.
I will look into a powermax... do i need to replace the whole "box" or just the converter part? It looks like it just wires into my existing panel. Am i correct?

Yes the WFCO has failed. Get the home charger on those batteries overnight before they are also shot.

If mostly plugged in I recommend PowerMax main board replacement converter. If you charge from a generator either an IOTA or Progressive Dynamics is best IMO. Don't spend money on a WFCO.

checked them... both are good.
also checked under load, DC voltage drops even more. lowest reading going out was 8.02 volts

Check the reverse polarity fuses.
