Question about Black & Decker 19" Electric Lawnhog Mulching Mower with Rear Bag
It appears that the mower shorted either in the winding or the solid state switch loacted on top of the motor. Is there an electrical wiring diagram available for the Black & Decker Lawn Hog 19"? Thanks, David
I had a MM875 go out after some months' service -- it actually went out with a bit of a bang. The problem was a shorted circuit; the weather was hot and the "solid state switch" on top of the motor shorted out. This part wasn't a switch but a bridge rectifier. The original part was specified a bit close to its actual working limits so I bought another (from Radio Shack, no less) that was higher rating -- something like 30 amps at 200 or 400 volts. ITs worked for years.
If it is a bridge then it will have two terminals labelled '~' and one each with the '+' and '-'. The plus and minus go to the motor (keep those connections the same as the original) and the others go to the supply wires.
