1. Connect an ammeter (100-amp minimum) in-line between generator terminal "B" connector and terminal
"B" of wiring harness connector. See Fig. 1
. Turn headlights and all accessories on. Depress brake pedal.
Operate engine at 2500-3000 RPM.
2. Measure and record generator output. See GENERATOR MAXIMUM RATED OUTPUT
table. If
amperage is as specified, go to next step. If amperage is not as specified, repair or replace generator.
3. Turn off headlights and all accessories. Release brake pedal. Operate engine at 2500-3000 RPM and
measure amperage under no-load condition. No-load amperage should be 5 amps or greater. If amperage
is as specified, go to next step. If amperage is not as specified, repair or replace generator.
4. Operate engine at 2500-3000 RPM. Measure voltage between ground and terminals "S" and "L". If 14.1-
14.7 volts does not exist, repair or replace generator. If 14.1-14.7 volts exists, generator output is okay.
GENERATOR MAXIMUM RATED OUTPUT NOTE: Check generator wiring harness connections and drive belt tension. Battery
must be fully charged before testing. Wait at least 30 seconds after starting
engine before measuring system voltage.
CAUTION: Ensure generator terminal "B" does not contact ground.
