Hi guys I'm new to the forum so here goes,as the title I can't charge the machine on the 12v supply mains or ciggy lighter,i've had it apart and there's voltage at the pins on the charger port.none of the leds are lit,I only tested on the top of the board not underneath,so was wondering if anyone has had similar experience/fix or has anyone got a wiring diagram or is there a fuse.the machine works as I can charge the battery on the bench to operate.
