CHECKING THE SYSTEM: Unplug the connector at
the wiring harness supplied by the O.E.M. Proceed to
make an A.C. output check. Place one lead of the A.C.
voltmeter into the center of the connector. Place the
other lead to engine ground (diag. 117).
With the engine running the minimum values should
read:
2500 R.P.M. - 16.0 Volts A.C.
3000 R.P.M. - 20.0 Volts A.C.
3300 R.P.M. - 22.0 Volts A.C.
If less than above output, the alternator assembly is
defective.
10 Amp Alternator System – Regulator-
Rectifier – External to Engine
In this system, the regulator and rectifier are combined
in one solid state unit.
CHECKING THE SYSTEM: To check the system,
disconnect the D.C. or B (+) wire at the switch end and
measure D.C. voltage between the lead and ground
(diag. 118).
With the engine running the minimum values should
read:
2500 R.P.M. - 13.0 Volts D.C.
3000 R.P.M. - 16.0 Volts D.C.
3600 R.P.M. - 20.0 Volts D.C.
If the minimum values are noted, the system is okay.
Check for a defective ammeter, wiring, etc. If less
than the above readings, disconnect the plug from the
regulator-rectifier, and insert the A.C. voltmeter probes
in the two outside terminals (diag. 119).
With the engine running the minimum values should
read:
2500 R.P.M. - 16.0 Volts A.C.
3000 R.P.M. - 19.0 Volts A.C.
3600 R.P.M. - 24.0 Volts A.C.
If the minimum readings are noted, the alternator is
okay.
