🔌 Function

The regulator rectifies stator AC output to DC and limits charging voltage so the battery receives a controlled charge without damaging electrical components.

Common signs of failure:

• Battery does not charge

• Charging voltage exceeds the safe operating range

• Tachometer becomes erratic or stops working

• Regulator wiring or connectors overheat

• Battery repeatedly boils, swells or goes flat

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
