I’m in a real pickle with my old Yamaha G2. The igniter seems to be giving up on me, and I’ve heard whispers about swapping it with a G9 CDI unit. Has anyone pulled off this swap successfully? I’m worried about messing it up and could really use some step-by-step guidance. Any help with this one would be good.
Response
I’ve been there and successfully swapped it with a G9 CDI unit. It’s a bit of a task, but here’s the gist: compare the wiring diagrams of both G2 and G9 from their service manuals, and match the corresponding wires carefully. If you’re looking for a cost-effective alternative, consider using a Chrysler ignition module, ensuring the wiring matches up. Remember to label your wires before disconnecting anything, double-check all connections, and test the cart thoroughly before finalizing. The costs can vary, but you might spend around $20 – $300, and it could take anywhere from 30 minutes to a few hours. If it gets overwhelming, don’t hesitate to seek professional help. Good luck with your swap!
