No matter how much you save fixing the 7345 you are still stuck with a mediocre converter that just slow charges.

Did you replace the fuse panel? This unit doesn't have a separate charging circuit, and if it is putting out 13.6 volts, it is fine. There are no relays in it.
Pulling the two 30 amp polarity fuses and the voltage runs around 13.4. When the fuses are out back in the voltage drops to 12.4 (or lowere depending on battery state). Pulling a load and the voltage will increase. Turn on 2 or 3 lights and voltages will I crease to 13.2+\-
As far as I know the two polarity fuses connect the battery to the power supply so they would be the charger fuse?
. There are relays. They switch the internal 12v circuits between battery and converter power. Pointless IMO if the converter was charging the battery's as it should be. Over complicated seams to be the build concept with this unit.

Those units are very easy to repair
A cap hidden behind the large heat sink (missing in the picture) is normally the problem.
Nice units can be run with or without a battery - not the fancy multistage unit but a wonderful 12 DC source for the shop. To date I guess I have repaired 50 or more of that exact unit never more than $5.00 in parts for each repair. Check the resister pack as well they tend to burn the PCB. Repaires to the board usually include adding some wires.
Good luck with the repairs
Thanks I'll take a look. The resisters at easy to test, the capacitor maybe I'll just replace and see what happens.
