How to Fix / Troubleshooting
Safety first: Turn OFF the generator and disconnect the negative battery cable before removing controller panels.
- Step 1 – Check controller fuse: Locate the low‑voltage fuse feeding the controller. Replace if blown with the correct rating.
- Step 2 – Inspect power and ground wires: Ensure the controller's DC power and ground connections are tight and free of corrosion.
- Step 3 – Reseat connectors: Carefully unplug and replug the controller harness connectors.
- Step 4 – Evaluate display: If the controller operates but the screen is dim or blank, the display module may be failing and the controller should be replaced.
