My GP760 turns over with the starter but won't start. The guages won't turn on and I just run the battery down. Mechanic last year replaced the stator and it work for two weeks then the same problem. Took it back and it started right up for the Mechanic after he charged the battery and then he wanted $200. It ran fine this spring and now the same thing is happening. Starter turns over but the display won't turn on and the PWC won't start. Is this a CDI problem?
