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. 111).
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.

On older point ignition systems, the A.C. output leads
are black and red.
