Hello All

I have had this Inverter for several decades and the only thing I ever remember getting out of it was a squealing noise when it was plugged up in the car. Vehicle battery is fine as I tried another inverter and it worked perfectly fine. Fuse was soldered to the connectors but it looks fine and seems to be a way higher rating (40 amps) then what is listed on the pcb (20 amps).

Suggestions?

Thanks.

 

Toss it, it's junk.
