Default Yamaha G1 eats through coils

Okay Iím back. I solved every issue with the cart except this now. The cart runs great with a brand new coilÖ for 10-15 mins. Then the coils all burn out. Anyone heard of this before?

What is your battery voltage with the engine running? What kind of coils are you using and where are you getting them?

Battery voltage with the engine running is 13.2 and it burnt up the original Yamaha one from 1984, a new OEM one and a Chinese eBay one. Another China one on the way. Iíve tried an OEM CDI and a stock one.. same issue.

If the engine is poorly grounded it could cause it to damage a coil too.

If not that, then Iíd have to defer to slo or mikeasis as theyíre a lot more familiar with this cart

Is there a write up on here about how he did it? Thereís not much to these in terms of ďpointsĒ. I do have a shovelhead at home that I converted to electronic but I didnít even know that was possible with these haha

I canít remember the post but I was just joking around about the HEI Iíve seen replacement CDI parts I would check the wire harness and check that coil is not grounding out

I know that the OG cdi parts are the best like my EZGO itís a 83 never had a spark problem ever so I would get OME parts and make shore that every thing is factory speck because Yamaha buildís good engine and parts

Update: the new China coil works but stops working after the cart warms up. I put the OEM yamaha one back in and same thing. Itís when the cart gets warmed up, it stops sparking. Any idea what causes THIS now? Iíve checked all the wires, connections, and hit everything with a wire brush and dielectric grease. I even ran a separate ground from the coil direct to the battery so I know itís not thatÖ

Ohm test your stator per the service manual listed at the bottom of my post especially if you can do it after it acts up. Sounds like something is breaking down when itís getting warm. If it passes then suspect cdi
