With the engine running the minimum values should
read:
2500 R.P.M. - 20.0 Volts A.C.
3000 R.P.M. - 25.0 Volts A.C.
3300 R.P.M. - 26.5 Volts A.C.
3600 R.P.M. - 29.0 Volts A.C.
If low or no voltage is experienced, replace the
alternator. If the alternator puts out the minimum
A.C. voltage, replace the diode.

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 (diag. 84).
With engine running the 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.
