🔌 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
