The electrical system starts the engine, powers its controls and carries the signals that monitor and protect it. This group covers starter motors, alternators and regulators, batteries and cables, wiring harnesses and connectors, relays and switchgear, and sensors. Gas engines add a category absent from diesels: the ignition system, comprising ignition coils, high-tension leads, spark plugs and the ignition control module. These are consumable items replaced at defined operating-hour intervals rather than on failure, and their condition directly affects combustion quality, emissions and the risk of misfire.

Ignition coils, high-tension leads, spark plugs including pre-chamber types on some models, and an ignition control module. These are consumables with defined replacement intervals.
Misfire, rough running, raised emissions and, in severe cases, unburnt gas reaching the exhaust. Replacement is scheduled by operating hours for that reason.
Contaminants in biogas and landfill gas foul plugs and electrodes faster than natural gas, so installations on those fuels use shorter replacement intervals.
