Got a question for you bright fellas. I was recently asked to work on an m75 apc . Finally got batteries hooked up. All the control panel lights lite up. Slipped it into what I can only guess is a start position, hit the switch and the starter sounded like it was spinning, but no roll over. Are there any special tricks to starting this beast? Forgot to say it was running when parked, but that was 20 years ago. I suspect it is froze up. Havent pulled it out on the craddle yet. Also twisted the little handle on the laft and all the lights went dim and nearly had a melt down, whats up with that? Noticed that the power box at the rear of the motornear the twin magnetos has a wire or 3 to be exact that were cut with the screw in plug missing that goes into the box, any wiring schematics?
