35 Watt A.C.
Before making any exterior tests, check for an
inoperative switch, shorted wires and burned out
headlight and/or stop tail light. To check out the
alternator, check the A.C. lead to ground at each
yellow wire (diag. 69).
With engine running, minimum values should read:
2500 R.P.M. - 8.0 Volts A.C.
3000 R.P.M. - 9.5 Volts A.C.
3300 R.P.M. - 10.5 Volts A.C.
3600 R.P.M. - 11.5 Volts A.C.
If the above minimum readings are noted, the
alternator is okay. Check for defective lights, wiring
or switches, if less than the above readings, the
alternator is defective.
NOTE: ON OLDER POINT IGNITION SYSTEMS,
THE A.C. OUTPUT LEADS ARE BLACK
AND RED.

1 Amp (18 Watt) Add-on Alternator
CHECKING THE SYSTEM: To check the system,
disconnect the plug from the rest of the lighting
system. Connect a No. 4414, 18 watt bulb in line with
each terminal in the plug. Start the engine and test
the circuit using a voltmeter as shown (diag. 70).
With the engine running the minimum A.C. voltage
values across the bulb should be:
2000 R.P.M. - 8.0 Volts A.C.
3000 R.P.M. - 10.5 Volts A.C.
3600 R.P.M. - 12.0 Volts A.C.
If minimum values are noted, the alternator is okay.
If the minimum values are not noted, the alternator
or A.C. connector is defective.
