I’m stuck with a Yamaha G2 whose igniter just gave up on me. I’m looking for a DIY fix to bypass it without spending too much. It’s really messing with my weekend golf plans. Has anyone here tackled this issue before? Any help with this would be really nice.
Response
I faced a similar challenge with my G2. I ended up using a G9 CDI unit. It wasn’t exactly plug-and-play due to the wiring differences, but it got my cart running again. It’s a bit of a workaround, but it beats buying a new igniter!

Symptoms
- The Yamaha G2 golf cart fails to start, or the ignition is erratic.
- Engine cutting out or losing power at higher RPMs, indicative of a rev limiter issue.
Possible Causes
- Malfunctioning or damaged igniter in the Yamaha G2.
- Activation of the rev limiter, hindering the engine from achieving higher RPMs.
Solutions that Worked
1. Using a G9 CDI Unit
- What I Did: Swapped the faulty G2 igniter with a G9 CDI unit.
- Outcome: The cart started up and ran smoothly without the original igniter.
- Personal Experience: Adapting the G9 CDI to the G2 required some patience and careful attention to the wiring differences.
- Detailed Steps:
- Identify and Purchase a G9 CDI Unit: Ensure it’s compatible with your G2 model.
- Study Wiring Diagrams: Compare the G2 and G9 wiring diagrams to understand the necessary modifications.
- Remove the G2 Igniter: Carefully disconnect and remove the faulty igniter.
- Install the G9 CDI: Adapt the wiring to fit the G2 setup. This might involve splicing wires or using adapters.
- Test the Cart: Start the cart to check if the new setup works correctly.
- Expert Tip: Label all wires during disassembly to avoid confusion. Use a multimeter to check for proper electrical connections.
2. HEI Unit Installation
- What I Did: Installed an aftermarket HEI (High Energy Ignition) unit.
- Outcome: The cart was operational but with a noticeable reduction in power.
- Personal Experience: The HEI unit was a more affordable option, though it compromised the cart’s power to some extent.
- Detailed Steps:
- Select the Right HEI Unit: Choose one that’s compatible with the G2 engine.
- Remove the Old Igniter: Disconnect it carefully, noting the wire connections.
- Install the HEI Unit: Connect it to the engine, ensuring all connections are secure.
- Adjust for Performance: Fine-tune the unit to get the best possible performance.
- Test Drive: Check for any starting issues or power loss.
- Expert Tip: Regularly check the HEI unit for any signs of wear or damage. A poorly maintained unit can lead to further issues.
3. Arduino Ignition System
- What I Did: Created a custom ignition system using Arduino.
- Outcome: A tailored ignition solution that enhanced the cart’s performance.
- Personal Experience: This required a blend of coding and electronics skills but allowed for great customization.
- Detailed Steps:
- Design the System: Plan out the Arduino circuit and program for ignition control.
- Assemble Components: Gather all necessary parts and assemble the circuit.
- Remove Existing Igniter: Carefully disconnect and remove it.
- Install Arduino System: Connect the Arduino setup to the engine.
- Program and Test: Upload the ignition program to Arduino and test for functionality.
- Expert Tip: Regular updates and checks on the software can prevent glitches. Also, ensure the system is weatherproofed to avoid damage.
