The Onan engines run pretty darn hot up front, and usually turn the front PTO & engine wiring to toast after years of service. Our new front service system for the engine compartment is just what the Doctor ordered! Heavier circuitry up front protected by our Cotton woven Tar/fiberloom helps fight off the heat on our Polyethelene crosslinked Marine wire. All new plugs and terminals throughout the front section along with soldered terminals makes this system up front pretty bullet proof! Match color for color. Includes the charging system section as well.
