You need to check the voltage at the converter or power distribution doing the same thing.

That is the only way to really know if the converter is doing it or it is a resetable breaker somewhere in the path to the batteries.

Checked at power distribution panel and the voltage is going up and down a few 10ths of a volt as the converter cycles up and down. Plus the fan goes on and off as the cycle starts at high amps and then goes off as it gets to low amps. Over and over and over

I see Go Power makes a converter smart charger that will fit in the same place as the WFCO charger.

Any reocomendations?

Well that pretty much confirms the issue.... Bad converter.

Many of us recommend the Progressive Dynamics series of converters.

If you have questions you can call them. Randy is the owner and he knows about installing and recommendations.

I wouldn't be so quick to assume the converter is bad. Many converters will have their output voltage sag a little bit under heavy load; they aren't perfectly regulated voltage sources, as that's not in the least bit required for this application.

The real question is whether the load is cycling for some reason, causing the converter's output to also vary, or whether the load is constant but the converter's output is varying undesirably. Neither one has been proven at all conclusively, from what I've seen, but it kind of seems to me like a varying load and a reasonably functioning converter.

There is no load except for the charging it's self.

Im ready to throw a new converter at it just to see if it works.

Interesting factoid. When I drew the batts down to 73% and plugged in the converter started to cycle. I left it unplugged and checked it again a few times and it still was cycling.

I decided to leave it plugged in for a while even though it is cycling it's still charging a little at a time. I checked it an hour later and the batts now up to 83% and the converter was charging as it should and no longer cycling.

Maybe it's when the converter is charging at it's highest rate of charge is when the problem occurs?

Regardless I think I will be going with the Progressive Dynamics 9260c.

Now I just have to figure where I'm going to get it.from.

Well now it just might be that the WFCO is thermalling out and shuts down the charge, cools off and starts charging again....

PROBLEM: Converter keeps shutting down.

SOLUTION: Ensure proper ventilation and check for obstructions regarding the cooling fan. WFCO converters are over temperature protected and will shut down.

FACT: Voltage will be present on both sides of the DC fuse terminals due to the LED circuit.

I have had my 9260 PD... for over 10 years and it has had lots of use... I installed it into my Magnetic converter cabinet years ago. I only ran two FWC batteries and switched to 1 100ah Lifeline AGM a long time ago.
