Feature Detail Page 2

This tool was designed to measure the strength of the magnets on the flywheel of the Model T Ford. These magnets along with the coil pack bolted to the rear of the engine generated the alternating current which was supplied to the spark coils for the ignition system. If the strength was low, the magnets were charged by using an electrical current through a couple of coils of wire. Not certain about the value of the numbers on the scale which reads from 0 to 100. We were checking these magnets before engine assembly and they mostly read about 35-40 on the scale. We charged the magnets and most went off scale. We actually replaced one of the original magnets we had installed because when tested it read 0 on the meter and the same after "charging". With the magnet off the flywheel it seemed to charge ok and read 90 on the scale, but we replaced it anyway. The gauge is in "as found" condition and in working order. The owner has decided to leave it in its present condition and not try to restore it. These photos were contributed by clubmember Chuck Christensen. Also shown is a page from the original manual for the guage. This photo was contirbuted by member Dan Manola of Illinois.
