My converter will not switch off bulk charge mode. It is a WFCO 9845 converter (Parallax upgrade kit purchased from Randy at BestConverter.com about 2 years ago).
Everytime the converter is on and charging batteries it is running at 14.4 volts and the fan is going full time. The batteries are completely full.
I have switched it on and off a number of times, unplugged it and plugged it back in and it still does the same thing. A few times it has gone into absorption stage charging (13.6 volts) for a period of time but then later will switch back to 14.4v.
I did have it disconnected recently to do a floor renovation. However, I am sure I connected everything back correctly and it was working after the floor mod. It works fine running the 12v
electrical in the trailer when the batteries are disconnected; as soon as I connect the batteries it jumps back to 14.4 and stays there.
My guess is the microprocessor inside the converter is shot. I have a call in to Randy at BestConverter to see what his thoughts are but wanted to see if anyone else has had a similar problem.
Thanks in advance for any insight anyone may have. jon
