ELECTRICAL AND IGNITION
16 Ampere Alternator System Test
(SMALL VOLTAGE REGULATOR/RECTIFIER)
1. Check battery voltage at battery with engine run-
ning.
2. If battery voltage is above 14.5 volts, replace volt-
age regulator/rectifier. Check condition of battery
as overcharging may damage battery.
3. If battery voltage is below 14.5 volts, charge bat-
tery; refer to “Charging a Discharged Battery”,
preceding. 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”, preceding. If
cranking voltage is not acceptable, replace battery.
5. If cranking voltage is acceptable, disconnect larg-
er diameter Red wire from STARTER SOLENOID
terminal.
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 NEGATIVE (–) ter-
minal of the 9 VOLT battery to the engine.
7. Connect RED (+) ammeter lead to larger diameter
RED wire, and BLACK (–) ammeter lead to POS-
ITIVE terminal on STARTER SOLENOID.
8. Secure wires away from flywheel.
9. With engine running at the indicated RPM’s, the
ammeter should indicate the following approxi-
mate amperes:
RPM
IDLE
1000
2000
3000
AMPERES
2
10
17
18
10. A reading of 18 amperes at 3000 RPM indicates
the charging system is functioning properly. The
battery is discharging due to the amperage draw
on the system is greater than the amperage out-
put of the engine charging system.
11. If ammeter reads less than 18 amperes, test the
stator; refer to “Stator Ohms Test (Alternator Coils
Only)”, [18 Ampere Stator], preceding. If stator
tests OK, replace voltage regulator/rectifier.
Optional 24 Amp Alternator System Test
(LARGE FINNED VOLTAGE
REGULATOR/RECTIFIER)
1. Check battery voltage at battery with engine
running.
2. If battery voltage is above 14.5 volts, replace volt-
age regulator/rectifier (a). Check condition of bat-
tery as overcharging may have damaged battery.
3. If battery voltage is below 14.5 volts, charge bat-
tery; refer to “Charging a Discharged Battery”,
preceding. 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”, preceding. If
cranking voltage is not acceptable, replace battery.
5. If cranking voltage is acceptable, disconnect RED
harness wire (b) from terminal (c).
6. Secure RED wire (d) on terminal (c) using hex nut.
7. Connect RED (+) ammeter lead to terminal (c)
and BLACK (–) ammeter lead to RED harness
wire (b).
8. Secure wires away from flywheel.
IMPORTANT: For accurate test results the voltage
at battery with engine running, in next step, must
be 13.5 volts or less. It may be necessary to oper-
ate electrical accessories to drop voltage to 13.5
volts or less.
9. Run engine at 3000 RPM.
10. Meter should read 20 or more amperes.
11. If meter reads 20 or more amperes, this indicates
the charging system is functioning properly and
the battery is being discharged because the am-
perage draw on the system is greater than the am-
perage output of the system.
12. If meter reads less than 20 amperes, test the sta-
tor; refer to “Optional 24 Amp Stator (Alternator
Coils) Amperes Output”, following. If stator tests
OK, replace voltage regulator rectifier (a).
