I have no answer for the question "does anyone know if a 02 998 has any in line fuses for ignition system". However, you really need to provide more details regarding the unwanted behavior you're experiencing if you want a proper diagnosis instead of a wild goose chase. For example; I recently had the following problem with my 02 998: Grounded out my battery on accident. This blew out the 40 amp fuse which I replaced. I also verified that the following items were OK too: Fuses in the fuse block as well as the coils. My 998 will no longer start. By that I mean the starter will turn over, but the motor will not fire up and run.[add as much detail as possible]. The motor is completely stock and no recent work has been performed priot to the problem.

I believe all of us would have more success if we clearly communicated the problem on the forum. I work in Techincal Software Support so I know first hand how difficult it is to communicate by text(email, IM, message board, etc;). I'm guilty of it too so don't take it personal. So post up more details and and let's solve this mystery!!! :)

No Start 998

Assuming fully charged and functioning battery. Assuming all grounds are properly connected Assuming starter spins the motor over fast enough to start.

Pull the plug wire off the front cylinder and connect to a dummy plug, ground the base of the dummy plug , ign. on, starter on and see if you are getting spark. If yes then it is not an ignition problem.

If no, check power (12+ volts) to the primary side of the coils with a volt meter.

Continue working backwards.

PM me for a wiring diagram if you get stuck

Patience

Good luck

Don't know about the 998 but the 916 has two fuses under the seat protecting (and near to) the fuel injection relays, could be those......

The 40A fuse is not a "main fuse"; it's between the battery and RR (Regulator Rectifier). So it's a "charging" fuse. It's there to protect the RR in case of a mishap like yours, for people that install their battery backwards (yes, it's been done!), and to protect the battery in case the RR "goes wide open", and tries to pump too much charge into the battery. The bike should start and run, even if this fuse is blown (it just won't recharge the battery when it's running). It's a great spot to connect an in-line amp meter (as opposed to an electronic clamp-on amp meter).
