So I found the parts to put together a CDI that kwest0425 had sticky'd to the yamaha gas forum. Didn't have to go to far either since my daughter's little 90cc mini-atv used that same 5 pin CDI. Picked up a couple of diodes while I was in town and 10 minutes later had a CDI wired up hoping it would solve all my woes. Much to my disappointment, it did not. I still only get spark in forward and not reverse. The cart runs just fine in forward with the improvised CDI. Ran it up and down the road for a bit without any issues. Just no spark in reverse. Anyone have any ideas.

Disconnect all 4 feed wires going to the magneto. Measure resistance from each of magneto wires to ground. The meter should show open on all leads to ground.
Measure from W/R to Br. Meter should show open.

I haven't but on the forum for a while but I happened to see your thread. I had exactly the same problem. Start and run in forward, would crank in reverse but no spark. Read my thread. Maybe give you some fresh ideas. Good luck.
