Hey everyone...I have a 2013 Salem that had a 55a WFCO Power Converter. The lights began cycling dim/bright/dim. I replaced the stock 55a convertor with a 75a convertor in March of last year. The lights are again dimming and brightening. Could it be a converter issue, battery issue, or something else? I put a battery charger on the battery and that fixed the lighting issue...now it seems some of the fuses are blowing. the battery charger was on 6a. I moved it down to 2a to see if it gets better...any ideas?

Thanks,
Mark

Could be the battery, would be wise to get it tested but more than likely it's the converter again. Did you get another WFCO? get a better brand next time -
it doesn't cost any more.

the battery... it has to take a charge and hold the voltage, and act as a buffer when connected to a charger or converter that kicks in and out (over-active), but dont overlook a circuit breaker that may be kicking in and out, so that sometimes the lights are being powered from the battery, and then when the circuit breaker resets, it allows the stronger voltage from the converter into to the light circuit...

or it could be working just opposite of this, so when the lights are bright, the circuit breaker has tripped and the circuit has been disconnected from a ground fault somewhere on th eother side of the breaker... and when the circuit breaker resets, the circuit again goes to ground and dims the lights, until the breaker trips again...

somewhere in here you may fine the answer to why the other fuses are blowing..

Since connecting the battery charger to the battery stopped the lights from surging, the battery is OK - or at least not causing the problem. There is no circuit breaker between the converter and the lights themselves.
Your converter is in its last throes of life. Suggest replacing it with a Progressive Dynamics 60A converter/charger.

I too, would suspect the battery.

If the battery has a shorted cell, it will start acting like a huge resistor, and drawing more power (trying to charge) than the converter can supply. As the battery gets worse, the dimming will increase to a point where there are no lights at all.

Take the battery out for a load test. Most auto parts stores will do the test, free of charge.

Yes Scott, I replaced it with a WFCO 9875 (75a). I'm gonna price some new converters, but gonna take the battery in to be tested to be sure. Thanks everyone!!

You need to separate the battery and converter for testing. Post the measured voltage of each. Turn on all the lights and run the water pump when getting the converter voltage. If the battery is less than 12.6 volts put it on the charger 24 hours then disconnect 24 hours and measure voltage. s/b 12.6+ volts rested and disconnected.

Battery is in and all seems to be working now. No more lighting issues, and the furnace stays on now. Still have a couple of fuses blowing for some reason, but I'll chase those later. Thanks everyone!!
