output circuit failure. I have troubleshooted and came to a conclusion the charger is at fault. Is there anyway I can fix this myself? or do I have to send it in for repair.

that charger only puts out about 7 - 7.5 amps on wall power. Reduce your wall power settings to 7amp or below and it should be fine.

on DC power you can run a full 10amps

edit: on second thought, what batteries are you charging? the 7-7.5amp comment only applies to 7.4v lipos. If your charging 3S or bigger you will need to use an even lower amp setting.

Actually youre wrong. For 2S on AC I have been doing 8amps for months. With DC it wont go to full 10amps, maybe 9.4- 9.6amps. Give or take.

On the LED screen CC output is zero. I get the error about 15 sec into charging.

I was going by what the directions for the charger state.

If you get input voltage error while on AC input, reduce the amperage of your charge and try again.

wrong error code you are thinking about. I have stated, "output circuit failure" youre advice only pertains to the input voltage error.

gotcha.. my bad
