Does anyone happen to have the original merc o tronic 55-138 power supply battery replacement unit like pictured? I have a broken wire from the transformer and need some assistance. I think I found where it should go but would like to confirm with someone that has the same unit before I try plugging it in and blowing something up.
Managed to repair my unit and get it fully functional, required a few parts but got there in the end. Attached is the schematic for the unit I have if anyone needs to repair theirs. There is also a more modern unit that has different components.
