hi to all i have this inverter 12v to 230v for use on my boat its a modified sine wave it was working fine
but then it broke i noticed the negative terminal was really loose so i tightened it but no luck
(all the neg wires in pic were loose inside case crimped ring was rattling on studbar.)
now it keeps restarting and the 12v side lcd builds up to 13v but 230v lcd stays on 000 then flicks off and restarts
cant see any bulged caps or any burns the reverse of pcb is clean
I am unsure how to further diagnose i have a basic multimeter
looks like 20 mosfets ?
4 transistors
6 transformers
and caps
8 fuses look ok
