Generator Load Test

Ensure drive belt is in good condition. Replace belt as necessary. If belt is okay, connect charging system load tester in accordance with manufacturer's instructions. Start and run engine at 2000 RPM, and apply load until generator output levels off. Generator amperage should be at least 87 amps with engine at 2000 RPM. Go to next step. If output is not as specified, see SYMPTOM INDEX  table under SYSTEM TESTS.
