🔌 Function

The solenoid receives a low-current start signal and closes the high-current starter circuit so the starter motor can crank the engine.

Common signs of failure:

• Starter will not crank

• Single click when key is turned

• Intermittent starting

• Burnt or corroded solenoid terminals

• Starter works when bypassed but not through key circuit

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
