OHMMETER CHECKS
Ohmmeter tests on the new style terminal
board with the quick-change voltage selector
switch, see picture on pg. 76 (Black plastic
part with 2 wires in it) is simplified if your
ohmmeter is equipped with the sharp,
pointed probes rather than alligator clips.
With the voltage change plug on the 230
volt terminal the Black wire in the plug is
positioned on Terminal “A”. Simply touch one
ohmmeter probe on the Black wire in the
voltage change plug to get the “A” terminal
reading. Another method is to remove the
terminal board screws and place the alligator
clip on the wire on the bottom side of
Terminal “A”.
