📜 Starting Troubleshooting Guide
| Symptom | Possible Cause |

| Starter keeps spinning after button release | High electrical heat has fused the contacts together. |
📜 Model Fitment
Confirmed Matches: Fits the following cruiser models:
- GV125 & GV125-S: All years from 2001 onwards (Carburettor & EFI setups).
- GV250: All Carburettor & EFI models, including the GV250DR.
- GV300S: All years from 2019 onwards (Bobber, SS, Supreme).
Starting issues can also be triggered by a weak battery that drops voltage under load. Ensure your charging system is robust and pair this replacement with a high-quality battery for clean, reliable cranking power every time.
🔧 Install Tips
- Safety First: Always disconnect the negative battery terminal completely before unbolting any heavy gauge starter wires to prevent accidental short circuits.
- Easy Swap: The small signal plug snaps straight into your factory loom. Only the two main copper battery terminal lugs need unbolting from the solenoid posts.
If you want to test whether your handlebar starter button wire is delivering a full signal or need advice on testing your starter motor draw, For circuit diagrams and guides from fellow cruiser owners, head to the forums.
