I've got a 2016 rockwood ultra 23 foot tt. it has a wfco wf-8955 converter in it. i first noticed the power center fan was coming on a lot more often. my batteries are old, so i just got 2 new 6 volt golf cart batteries. getting ready to install them but i'm suspicious that the converter is bad. here's what i've done
with batteries out, shore power on do not have 12 volts at battery terminals. fuses and disconnect switch at battery test good for conductivity. no obvious signs of damage to the wiring around the battery. checked the reverse polarity fuses and they are good.
inside , with shore power and no batteries, i have lights, water pump runs but not slide outs. so it looks like i've got 12 volts inside but only for low power. if i flip off the 120 volt breaker labeled conv, the lights go out. flip the breaker on, lights come on, the power center fan briefly comes on.
can my converter be bad but still provide low load power for things like lights but not charge the battery?
don't want to spend $200+ to throw a new converter at the problem. but not sure what else i can try. thanks for any help
