I keep blowing fuses. I traced every wire the kit comes with and can't find any wires which might be grounding out and all is fine.
This is what happens. I turn the key on, tap the starter button and all you hear
is the relay click. If you hold the button for more than a couple of seconds it will blow a fuse.
This kit has been trouble free since I put it in but today I was going to start it and all I got was the click from the relay, noticed the fuse had blown.
I called Matt but it's a Saturday. Hope he is reading this and can chime in.
Anyone else know what I can try?

The first thing (or a thing) you could try is you could disconnect the output from the relay(wire going to the starter solenoid), and then try.
 
If it use to work and now it doesn’t then I’d trace every wire for any shorts. @cNw may have more suggestions.
 
I traced every wire already and all is fine. No breaks in the wires at all.
Now, disconnecting the output wire does what?
 
it Sounds like the solenoid has a problem, as the heavy starter cables aren’t fused. Does the starter try to turn when the button is pressed?

Cheers,

cliffa.
 
All you get is a slight clicking from the relay and then the fuse blows.
I pulled the little wire from the starter, the little one, not the primary cable and the relay clicks and the fuse doesn't blow. I plug the little wire back to the starter and the fuse blows.
 
Any chance your battery is going through its bucket list? Are your high current cables making proper contact? Do you have a ground loop. Is the high current lug on the starter loose? Is there any chance is jammed? (if you can kick it through a few engine revolutions without hearing the starter dragging the starter, probably, isn't caught) If your answers to the above are: No, Yes, No , Yes and No then better call Saul, er Matt

Isn’t there only one small wire ( white / red) on those? If so I can’t understand why it would still click when that wire is disconnected.
 
As far as the wires to the relay, they are bundled to a connector. I have to figure which number the wire is on the relay for the output
 
Hi Guido,

Is it possible something is arcing on the hot lead terminal on the starter motor? NYC Norton have done many installs on these beautiful units, and we make extra sure nothing touches (e.g. braided stainless rocker line) the hot HT pole on the front of the starter motor.

Also, check that your relay terminal plug is still tightly connected to the relay itself. Sometimes these get disturbed and slightly unplugged with interesting results.

Easy things to check.

I am wondering if the supplied by CNW starter switch may be the culprit. I had a brake fluid leak at the M/C and it got the switch a little wet but that was like 4 months ago and I ride this all the time so maybe thats not it.
No wires are loose, arching or touching. Could a bad relay do it?

Guido,

Just saw this thread now. I will contact you in the morning and we’ll work through some trouble shooting. Will get you up and running again

Sorry for the trouble

Matt
 
If you "hot wire" the solenoid's by removing the small gauge wire that comes from the starter button and WITH THE MOTORCYCLE IN NEUTRAL and Ignition off (do not pull the plugs or the high voltage wires/caps), If your Norton is wired with a (+) ground harness run a jumper wire from the terminal on the starter that gets a signal from the starter button and touch that jumper to the (-) terminal on the battery (reverse the "plus" and "minus" symbols above) and the starter should engage and spin the engine normally. It it doesn't the issues are in the starter or the primary. If the test produces the expected results your issue is in the harness or the switch's. If the harness is the original and any of your switch are also original I would gently suggest replacing the harness (or make one) and replacing or rebuilding the aged switches.

I had gone thru the whole bike about 6 years ago. New harness from Commando Specialties. Great loom. Then went thru all the switches and cleaned them all. This CNW starter is on it's own dedicated circuit. I'll try tapping the solenoid with a small ball/peen hammer to see if it's the solenoid. Gently of-course.
But, can a relay go bad and cause this?
 
Thanx for the reply Matt. As always you come thru in a pinch.
As far as the battery goes it's a new 18 amp AGM and registers fine for load and voltage.

Well, one thing it does is that it eliminates anything to do with the actual starter motor should the issue persist. If the issue did not persist, then that would tell you that the issue does have something to do with the starter (likely solenoid). You could just simply pull the wire out of the starter solenoid to determine which area you would be best looking at.

A similar approach in respect of the relay itself would also narrow down where the (fuse blowing ) issue is to be found.

This is where a circuit breaker (that resets itself) can be of a bit more use than a fuse that blows.

No. I assume the fuse that's blowing is the supplied blade fuse that feeds the starter solenoid? If disconnecting the wire to the solenoid stops blowing the fuse then the problem is with the solenoid.
 
Hmmm...If the solenoid engages and then the fuse blows a few seconds later, I wonder if the starter motor is either defective or, for some reason, not able to spin - that is, something is binding in the motor/assembly. If there was a short in the solenoid itself,I would expect the fuse would blow immediately when the button is pressed/solenoid is engaged.

In any case, I know Matt will sort it out
 
Replace the fuse, turn the key on and KICKSTART the bike... If it runs fine and all the lights and signals work, then you can focus your troubleshooting on the electric start circuitry... Maybe that's incredibly obvious, but the fact that the bike runs normally tells me where my short is NOT...

If I could I wouldn't need the electric start. Bad knee aside, it does turn over just not enough for me to start it.
That was a great quote though.
