Is there a way to bench test a magneto to see if it's firing? I had mine into a repair shop for repair-I think he just did points and condensor-and when I put it on the WD it was firing O.K. but I didn't know how to time it. After much fooling with it I had a hunch it wasn't firing anymore and I took it off and looked inside and the points wern't opening at all. I reset the points and would now like to benchtest it before reinstalling. I assume the screw adjustment had just loosened. Should I put some locktite on this or is there someother problem? I think I know how to retime it now from info on this forum. Thanks for the info.

Clamp the mag in a vice and insert a piece of stiff wire in one of the plug wire sockets. Bend the wire so that it is about 1/8 - 1/4" away from some bare metal on the base of the mag. turn the mag over by hand. after it has clicked 4 times a spark should have jumped to the mag base one of the times. if you have got spark so that you know that you are on the right post in the cap you can turn the mag backwards so that you get spark the next time it fires.

I test my I-H mags by spinning them with a socket chucked in my electric drill.
