Product Description
Yamaha G1 Gas Golf Cart Starter Generator Solenoid (1982-1989)
Part Number: J17-81950-01 | 12V 100A 6-Terminal
Restore the reliability of your vintage Yamaha G1 gas golf cart with this premium heavy-duty solenoid. Designed specifically for the unique electrical architecture of 2-cycle engine models produced between 1982 and 1989, this component is critical for engaging your starter generator and maintaining proper charging functions.
Over time, original solenoids suffer from contact corrosion, coil fatigue, and terminal wear, leading to frustrating no-start situations. This upgraded replacement features high-purity copper contacts and a robust housing to ensure years of dependable service.

⚠️ Symptoms of a Failing Solenoid:
Clicking but No Start: You hear a loud click when pressing the pedal, but the engine does not turn over.
Intermittent Operation: The cart starts sometimes but fails at other times, often depending on temperature or vibration.
Stuck Starter: The starter continues to run even after releasing the pedal (dangerous – replace immediately).
No Charging: The battery fails to charge while driving, as the solenoid also manages the generator circuit in these models.
Visible Damage: Burnt terminals, melted plastic, or heavy corrosion on the existing unit.
📝 Installation Guide & Tips:
Safety First: Disconnect the Negative (-) battery cable to prevent accidental shorts or sparks.
Document Wiring: CRITICAL STEP: Before removing wires, take a clear photo of your existing solenoid's wiring configuration. Label each wire with tape corresponding to its terminal position. The 6-terminal setup can be tricky if wires are swapped.
Remove Old Unit: Unscrew the nuts holding the wires and remove the two mounting bolts.
Install New Solenoid: Mount the new J17-81950-01 solenoid in the same orientation.
Reconnect Wires: Refer to your photo/labels to reconnect wires to the correct terminals. Ensure all nuts are tightened securely to prevent arcing.
Test: Reconnect the battery. Lift the rear wheels off the ground (safely), put the cart in gear, and press the pedal. The engine should crank smoothly.
