CHARGING & STARTING SYSTEM
90-857046R1 NOVEMBER 2001 Page 2B-7
15 Ampere Stator
1. Check battery voltage at battery with engine running.
2. If battery voltage is above 14.5-15.0 volts, replace voltage regulator/rectifier. Check con-
dition of battery as overcharging may have damaged battery.
3. If battery voltage is below 14.5 volts, charge the battery. If battery can NOT be satisfacto-
rily charged, replace battery.
4. If battery accepts a satisfactory charge, check battery voltage while cranking engine. A
minimum of 10 volts should be maintained while cranking (at room temperature of
75°F/23°C). If cranking voltage is not acceptable, replace battery.
5. If cranking voltage is acceptable, disconnect the RED (voltage regulator) wire bullet con-
nector from the RED/PUR wire.
6. Connect RED (+) ammeter lead to RED voltage regulator wire and the BLACK (–) am-
meter lead to the Red wiring harness wire.
7. Secure starter wires away from flywheel.
8. With engine running at the indicated RPM’s, the ammeter should indicate the following
appropriate amperes:
0
2
4
6
8
10
12
14
16
0123456
RPM x 1000
Alternator current (Amps)
9. A reading of 15 amperes at 5000 RPM indicates the charging system is functioning prop-
erly.
10. If ammeter reads less than required amperes @ 5000 RPM, test the stator (refer to “Sta-
tor Ohms Test”). If stator tests OK, replace rectifier/regulator.
