I have a 1992 trx250x that has no spark at all. When I bought it, it started and would idle but when I got it home I couldn't get it to idle at all. Now it won't even start. I've tested the ignition coil and it seems there is no continuity so I'm replacing that. But I'm wondering if there is any other problem because before I owned this quad it was flipped. I can see from the owners manual that there is supposed to be an on/off switch on the quad but it isn't there anymore as a result of the previous owner flipping it. Does anyone have any suggestions/ideas about that? I'm just wondering if the original ignition coil isn't allowing voltage through it because of an open circuit somewhere since there is no on/off switch. I have checked to make sure it's getting fuel and has compression, like the service manual says, but I am new at this so I'm open to all suggestions.
