My son has a 2004 90 4 stroke AC ATV and it just quite on him one day while riding. I checked for spark and no spark so I took it to a friends that knows a lot more than me on this stuff. Well, he did a bunch of testing that is way over my head and came up with CDI so I told him to go with a new one. He put the new one in and it ran great for about 2 to 4 minutes and then died on him. He pushed it back into the garage and now it has no spark once again. He still has power to the CDI box but no spark. Well, it does spark once when the key is turned on but that is it.
He is puzzled and I don’t want to keep throwing CDI boxes at this as the quad is only worth about 600 bucks in running condition.
We did check the oil and that is good so it is not a low oil shut off killing the spark. We have also jumped the brake safety switch so it is not that killing spark. I do not have a manual so we are hoping someone here has some insight on what we should look at next.
