HOUR METER IS NOT OPERATING WITH ENGINE RUNNING

NORMAL OPERATION:

1. Engine stator puts out 22 VAC at 2400 rpm.

2. Diodes D1 and D2 rectify 22 VAC down to 13--15 VDC.

3. The 10--15 VDC output from D1 and D2 powers up the hour meter.

CHECK VOLTAGE ON WIRE 14/GRN AT THE HOURMETER.

10--15VDC

0VDC

ENGINE RUNNING

CHECK VOLTAGE FROM BATTERY POSITIVE TO

WIRE 13J/BLK AT THE HOURMETER.

TURN ENGINE OFF. DISCONNECT D1

AND D2. WITH MULTIMETER IN THE AC

MODE AND ENGINE RUNNING AGAIN,

MEASURE AC VOLTAGE FROM WIRES
