OP needs to disable his solar or he could get false readings.

OK by checking battery voltage you have verified no converter power getting to the battery.
Most likely the converter is dead. You may as well remove it for a bench test. Yes you are looking for about 13.6 volts output any time it is powered up. Don't replace it with a WFCO.


Do not have to remove it. Just disconnect the output wires. Turn on the converter and measure the empty output lugs. Not rocket science.

I disconnected the 2 positive cables from the electric panel. I assume one of these cables goes to the battery, the other the converter.
One cable showed 12.6 (which is the current battery level), the other cable shows 0.00V

You have definitely confirmed your converter is not making 12 volts dc. You need to confirm that you have 120 volts ac feeding your converter as previously described in this thread. You cannot have 12 vdc out if you have no 120 vac into it. If you confirm 120 vac, you definitely have a problem with the converter. If you do not have 120 vac to the converter, you must resolve that problem.

Update: I installed a new Progressive Dynamics converter series 4600 today and everything is working again. I also installed the optional remote control for the converter which shows what the converter is doing at any given moment (what stage of charging it is in).

Before I installed the converter, the battery was a 12.6V (thanks to the solar panel). Once I turned on the new converter, it jumped to 13.4V and it's been in the converter's 'normal' stage of charging since then.
