Safety-critical: confirm before use
Safety first: park on level ground, stop the engine, and secure the machine before any inspection. Thresholds, component locations, wire numbers, fuse locations, and reset procedures can vary by model, configuration, and serial number. Confirm them in the service documentation for your exact machine.
