Disconnect rectifier-to-regulator harness at voltage regulator.
With jumper wires, connect pin E of harness to a battery
negative terminal and pin B of harness to positive terminal of
the same battery. With vehicle engine running at idle speed and
ultimeter set on the dc volts scale, place red lead on pin C
of harness and black lead to ground. Multimeter reading should
be between 30 to 34 volts. If this voltage is not present, repair
or replace rectifier-to-regulator harness (p 6-76). If this voltage
is present, go to step K.

K MASTER switch OFF. Disconnect voltage regulator to
bulkhead harness at voltage regulator. Use a jumper wire to
connect socket A to socket B. Place MASTER switch to ON
position and start engine. Run engine at 1000 rpm (oil pressure
12 psi). Place red lead of multimeter in socket F and black lead
to ground. If voltage is 24 vdc, troubleshoot air cleaner blower
motor circuit (p 2-113).
