Generator No-Load Test
- Connect voltmeter positive lead to B+ terminal on generator and negative lead to ground. Start and run engine at 2000 RPM with no electrical load (all accessories off). Read voltmeter when voltage stabilizes. Voltage should be 13-15 volts. If voltage is not as specified, see SYMPTOM INDEX table under SYSTEM TESTS.
- Turn A/C on, blower motor on high speed and headlamps on high beam. Voltage should be within 0.5 volt of previously measured voltage. If voltage does not increase as specified, see SYMPTOM INDEX table under SYSTEM TESTS. If the voltage is as specified, charging system is operating normally.
