Hi Mr. blood89,

Welcome to the forum, sorry for your troubles. About all I can do right now is point you toward some troubleshooting procedures.

How To Repair Your Wiring Harness

Cleaning Your Wiring Harness

If you are blowing fuses you must check your wiring harness for wires with worn insulation that may be shorting to the frame or each other. Look for melted connectors and wiring. Check and clean every connection and ground on the entire wiring harness. Visit my website for manuals and wiring diagrams.

I also stopped by to welcome you to the forum in my own, special way.

I can tell you exactly what it is..I had the same issue...lights would come on but no starter and no ignition..pull your headlight out and there is a white square plug with 6 wires (in the headlight bucket). One is ignition and one is starter. play with the plug and you will probably get it to bump. If thats it, just wire in a new plug or direct wire the corresponding wires. mine ended up being a short in the plug. Hope this helps.

[blood89]

hey i direct wire the corresponding wires and still nothing. any more idea?

How did you verify you had spark?

[blood89]

im going to recheck to see if i still have spark. whats the best way in checking?

[chef1366]

Figure out why there isn't power to the starter, you're blowing the main and then you will probably have spark.

Hello,

This probably will not be much help, but your electrical is working besides the starter correct? If not, I just had a fuse and the electical go out on mine while on the highway of all places, and it ended up being the rear brake light switch. I am no expert, but continue to check all possible "circuit ends" with a coltage tester, etc., that run through the main fuse, and I would think you should be able to narrow it down. Hope this helps.

ok i put this to the side for a few weeks but im back at it. i think my cdi is bad. i have no spark at all on any plug and my starter is turning when i jump the bike. but the button i hit to start the bike will not do anything. would a bad cdi do this. i can get a used one for 99 but dont want to spend the money if its not it.

Before spending money on a new ignitor, here is how to test it:


According to the service manual here is the Suzuki test method

Here is how to test your ignitor


Remove each spark plug of #3 and #4 cylinders, fit it
to the plug caps and place it on the cylinder head.

Remove the frame cover on the right side and disconnect the lead
wire from the signal generator.

Connect + lead of voltmeter (set on ohms) with blue lead
wire on the ignitor side and - lead on the voltmeter with the green
lead wire.
The moment the test pins are connected the spark plug of #4 sparks
and the moment the tester pins are disconnected the spark plug of
#3 cylinder sparks.


If you don't have one, get yourself a wiring diagram and a volt-ohmmeter.
Blowing fuses is not normal, you have a short somewhere.

Have you gone through your bike and cleaned ALL the connections?
