Wfco power center going bad?

[stew47]

Hello everyone. So the day I bring the camper home from getting greased and brakes (cause I blew the seals out) I noticed the camper was dead. It was off the shore line for a week. Didn’t think much of it, plugged into truck, hooked up and brought home. I plugged into shore line at home and ran slides out. They were slow. Noticed the converter was buzzing so I took the cover off. It had stopped buzzing by then and there was no sound, 10 volts to dc side, was looking at my disarray of tools and the converter clicked, lights brightened then was off again. Any thoughts? Wf 8965

WFCO's are bad when they leave the factory. (Esp the converter charger portion of them).

Lol battery is bad and the converter. The converter never kicked on while running furnace so I unhooked the battery and the converter put out 5 volts.

If I do have to replace the converter which I’m pretty doubtful now.... I think I’d be ok with little smaller one. I’ve replaced all my lights with led and sometimes I’ll throw the 30 amp breaker when everything is on and the converter kicks on. Course I doubt the difference would be half an amp.

Actually I do recommend a smaller converter unless the OP has an extra large battery or large 12v draw such as multiple tank heaters. Especially when going with a Boondocker converter due to the charging profile.

Charged all night, 10 volts, threw battery tester on, weak, getting a new battery.

I don't think you want to replace a 65amp board with a 45amp board.

I would first get the battery checked. They short internally and will not charge. When they short, they sit at around 10V.
If battery is OK, it's new converter time.

I agree; sounds like the battery. You specifically said it was dead when you got it back from the shop, It may have been drawn down (or shorted) and not recharged to the point it was damaged. Get the battery check first before going through a converter change out that wont do anything for a damaged battery.

Yea that’s good advice. I’ll do that tomorrow.

I came back out to take a look again. Batteries are now at 11, converter buzzes for a while , kicks on, provides 14.4 volts then quickly shuts off. 4 weeks till Florida. I’ll just replace with little better converter and be done with.

My WFCO was not functioning the day it was installed at the factory. It did not charge above 13.6 volts even when I let the battery get low on purpose. I installed a Progressive Dynamics and when I plugged in the TT, the digital voltmeter went straight to 14.4 volts and charged the battery quickly, the converter then switched to 13.6

if your battery was dead in freezing weather it is now frozen your wfco will not like that you may now have a shorted cell in the battery
