Electrical/ converter issue

I suspect a converter issue but I need help. I have been having this issue since I accidentally left some lights on for several days in the camper, although I was on shore power. My battery indicator light shows a weak battery, however I had the battery checked, it is fine (new battery, almost 13 volts). My converter fan does not work. All the lights do work, but they don't come on right away, takes a few seconds.

I thought maybe I shorted out the fuses when I changed the battery, but the 2 40 amp fuses are fine. From what I can gather I may have low voltage coming from the converter and need to replace it. I am not confident in fooling with the converter, checking voltage etc. and will just take it in for replacement if that looks necessary. Am I on the right track?

Final update: My brother, who has considerable electrical experience, examined my problem. He discovered one of the battery cable connectors was never properly crimped (it came loose in his hand). After repairing the cable everything seems to be fine. Now I owe him a favor lol.

Update: I reviewed my insurance and I have an extended service policy that covers converters. So all I have to do is bring it to my dealer (free) or a licensed repair shop ($50 deductible). As I recall, the policy was expensive, but runs 7 years and covers most equipment failures.

I will be using the camper this weekend but will be on shore power. I will minimize the use of interior lighting. I hope that avoids any issues, then I can bring it in for repair next week.

If you've got a regular battery charger you can throw that on for a while, or charge the batts with the engine. If the 12V stuff works like it used to when the charger is on, its definitely your converter.

If you have a 2011 WFCO converter, it time for it to go out about now. Change over to a PD, or you'll have the same problem in another 3 years.

Thanks for the responses. I will try to find a mobile tech, fix the problem and go from there.

If you confirm that the converter is dead, call Randy at Best Converter. He is really good at matching a great converter to your rig.

If you are out of warranty on your charge controller, I have a PD9245 for sale, with pendant for bulk charging with the push of a button. Private message me if this interests you.

2011 Rig could still be under warranty. You need to try to locate your converter. The converter could be covered by the converter's manufacturer's warranty
The newer converters are not that prone to failing. I would look for some other issue.

Sounds about right. Besides, the converter should fully charge the battery when plugged into shore power for an adequate length of time.

I have no idea what kind of converter I have. I don't even know where it is.


Tiger, what kind of rig do you have? The converter is usually mounted low somewhere where you can get to it. It will have a door that opens and you'll see breakers and fuses inside. The make and model is usually on the door. Could be a bad converter.

I just went thru a similar thing and it was the convertor. While on shore power, the battery indicator just kept going from green to yellow to red...to nothing. The convertor was not getting any power to the batteries, thus dead batteries. Had my repair man out and it was an easy thing for him to diagonose.

I would suspect your batteries first.
