Troubleshooting the Onan Generator Hour Meter

If the hour meter on your Onan generator isn’t working, you can systematically troubleshoot the issue to restore its functionality. The following steps will guide you in identifying common issues.

Checking Power Supply

Start by checking the power supply to the hour meter. Ensure the generator is operating properly and generating power. Use a multimeter to test the voltage. If the voltage is low or nonexistent, inspect the battery and alternator. A weak battery can lead to hour meter issues, so consider replacing it if necessary.

Inspecting Connections

Next, inspect all wiring connections related to the hour meter. Look for loose, damaged, or corroded wires. Pay particular attention to the harness that connects the hour meter to the generator’s control panel. Tighten or replace any damaged connections, as these can disrupt the hour meter’s function.

Testing the Hour Meter

Finally, test the hour meter itself. Remove it from the control panel and connect it directly to a known working power source. If the meter operates as expected, the issue lies within the generator’s connections or wiring. If it doesn’t work, consider replacing the hour meter to resolve the problem.

Solutions for Repairing the Hour Meter

If your Onan generator’s hour meter isn’t working, you have several options to consider for repair or replacement.

Repairing or Replacing the Hour Meter

Start by determining the extent of the issue with your hour meter. If it’s a simple wiring problem, fixing or reconnecting broken wires may suffice. Ensure you use appropriate tools, like wire strippers and connectors, to secure connections.

If you find the hour meter itself faulty, replacement may be necessary. Purchase a compatible hour meter model for your generator. Follow these steps for replacement:

1. Disconnect Power: Always turn off the generator and disconnect the battery before starting.
2. Remove Existing Meter: Unscrew and detach the old hour meter carefully.
3. Connect New Meter: Follow the manufacturer’s instructions to connect the new meter, ensuring polarity is correct.
