* DC Resistance of these windings generally is less than 1.5 OHMS.
If a reading (resembling a short) is obtained, this would be accept-
able.
** If stator is removed from engine, connect test lead to black stator
lead, if provided.

Alternator System Test
UNREGULATED SYSTEMS
IMPORTANT: Rectifier must be functioning properly
for accurate test results to be obtained.
1. If engine is equipped with a voltage regulator, discon-
nect voltage regulator leads at rectifier; re-install hex
nut on rectifier terminal that has yellow stator lead.
2. Remove red wire from (+) terminal of rectifier.
3. Connect red (+) ammeter lead to rectifier (+) terminal
and black (-) ammeter lead to red rectifier wire.
4. Run engine at 3000 RPM.
5. Meter should read 7-9 amperes; if not, replace stator.
REGULATED SYSTEMS
1. Check battery voltage at battery with engine running.
2. If battery voltage is above 14.5 volts, replace voltage
regulator/rectifier. Check condition of battery as over-
charging may have damaged battery.
3. If battery voltage is below 14.5 volts, charge battery;
refer to “Charging a Discharged Battery”. If battery can
NOT be satisfactorily charged, replace battery.
4. If battery accepts a satisfactory charge, check battery
voltage while cranking engine; refer to “Charging a
Discharged Battery”. If cranking voltage is not accept-
able, replace battery.
5. If cranking voltage is acceptable, disconnect larger di-
ameter RED harness wire from starter solenoid termi-
nal.
6. Remove smaller diameter RED wire (sense lead) from
starter solenoid terminal and connect to the positive (+)
terminal of a 9 volt transistor battery. Ground the nega-
tive (–) terminal of the 9 volt battery to the engine.
7. Connect RED (+) ammeter lead to larger diameter
RED harness wire, and BLACK (–) ammeter lead to
positive terminal on starter solenoid.
8. Secure starter wires away from flywheel.
9. With engine running at the indicated RPM’s, the am-
meter should indicate the following appropriate am-
peres:
