My MultiPlus Compact 12/2000/80-30 230V has stopped charging after several years of normal operation.
Symptoms: when in "on" mode, green light is on and there is 230V to consumers whether shore power is on or off, but no charging voltage to battery when shore power is connected. When in "charger only" mode and shore power connected, yellow light is off and no charging voltage to battery. The red alarm LED (the one inside on the PCB, not the one on the front panel) seems to be faintly lit as soon as shore power is connected.
Others have posted about a thermal circuit breaker mentioned in the manual; like them I can't see any breaker to reset. The large ceramic fuse to the top R of the box is OK. I also disconnected the temperature sensor (manual describes as optional) but no change. Voltages: battery 12.4V shore power 244V.
Question: is there a thermal breaker, and if so where is it? If not, what else could this be?
Thanks in advance
