MVA American Bosch Magneto Instruction Manual

The MVA is an unusual American Bosch device that looks a lot like the famous MJA,MJB,MJC Et al without the housing.   Very seldom seen, but uses a rotating magnet and a stationary coil and probably worked well in the day for smaller low compression engines. It likely did not fare well with the usual ravages of moisture, neglect and physical trauma. Here are some images from an American Bosch instruction and parts manual to get yours back on line.

Yer magneto is probably out of warranty.
