Power converter cycling on and off

I have a 2002 Lance 815 truck camper. I currently have the camper plugged into AC power bc my battery needs to be charged. I can hear the power converter constantly switching on and off. It seems to go on for about 10 sec. then switch off for about 50 sec. When it's on the battery is being charged. I can tell bc the battery monitor shows a full charge but then when the power converter switches off the battery monitor shows a low charge. Is this normal or should the battery be constantly charging? If its not normal what could be the problem?
  • You won't be disappointed with the PD. I love mine.
  • Ok problem not solved. It went back to cycling on and off. When it's on it's only charging at 12.5v. I believe it's supposed to charge at 13.6v so I think something's wrong with my power converter. I just ordered a progressive dynamics converter/ charger with built in charging wizard. Amazon seemed to have the best price.
  • Problem solved. It was not supposed to be cycling on and off. It must have been a short due to low water in the battery cells. I filled them with distilled water and no more problem. Thanks for the tip!
  • I have a magne tec model 6235 power converter. In the battery compartment there is a sticker that says " 40 amp circuit breaker located inside camper on side of battery box*** to reset breaker, disconnect and reconnect power at battery."

    Do you know if you have circuit breaker type fuse or a regular fuse installed between the converter and the battery terminals. This will be real close to the battery terminals.. The circuit breaker didn't normally show up with the older models.

    You need to put a multimeter on the battery terminals and see what is happening. The older converter/chargers put a continuous 13.6VDC. I would check the battery fluids in your battery as it could be one of the battery cells is shorting out...

    give us the model number of your converter/charger unit.
