“Pilot light indicates instrument is ‘on’. Connect test lead to armature plate casting. Connect other lead to cutout lead or ‘hot’ side of breaker assembly. Rotate crankshaft until breaker points close. Clean or replace points that are in the ‘red’ range. New breaker points may show in ‘red’ range until magneto is sparked for a few seconds.”
