Possible Causes

Loose high‑current connection, Failing contactor in ATS, Overheating AVR, Undersized wiring or poor lug terminations

How to Fix / Troubleshooting

Safety first: Immediately turn the generator OFF and disconnect it from load (ATS to utility). Do not continue to operate until the source of the smell is found.

  • Visual inspection: After cooling, open the generator panel and look for discolored, melted, or charred wiring, connectors, and components.
  • Check lugs: Tighten any loose output lugs and neutral/ground connections with an insulated tool.
  • Inspect AVR and control board: Look for bulging components or burn marks. Replace any obviously damaged modules.
  • ATS inspection (electrician): Have an electrician inspect the ATS contactor and wiring for overheating.
