Load Test

WARNING: This page is about a different variant/trim than selected.

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 engine and bring to normal operating temperature (it takes at least 2 minutes for glow plugs to time-out). Run engine at 2000 RPM and apply load until generator output amperage levels off. Generator amperage should be 87 amps with engine at 2000 RPM.
