Nuetral switch bypass?

[NNJ650 bobber]

Hi, new to the GS have been bobbing a 81 GS650GL and it will not start now. The lights work and the horn works but nothing when I try to jump it. I have already bypassed the clutch safety, question is without the gauge cluster hooked up is there some sort of safety fault with the nuetral switch? and if so how can I bypass it? Thanks for any help

I'm not familiar with your bike but I really doubt there is a neutral safety switch. As far as I know, there was only the clutch swtich. Most likely it's the contact on the starter button. Try spinning the starter button as you have it pushed in to grind off any corrosion that might be there. have you tried jumping the starter solenoid?

This assumes of course that you have a good battery.

No kind of neutral safety switch - just the clutch safety switch. Head to Basscliff's site and steal a wiring diagram which will explain the electrics on this bike. When you say " jump it"- what exactly do you mean? Does the starter solenoid click, or lights dim when you press starter button?

When I say jump I mean hook bike to car battery not running of course and try to start, the lights do not dim. I also found the ground to the rectifier? ( small finned electric unit under the airbox ) ran to a bolt that holds it onto the plastic airbox I assume its suppose to be to the frame?

Could also be a faulty kill switch as well.

The ground wire to R/R isn't causing the no start- but more about that when you get the solenoid to click and the starter to turn. Positive power is sent thru ignition switch and on to kill switch which then lets ignition system have power. When you press starter button ( you said you bypassed clutch safety switch), solenoid should at least click- of course, you need a decent battery. Any clicking on your bike,even connected to non running car battery?

[NNJ650 bobber]

Yeah I am getting no noise no response when the start button is pushed. I guess I will take apart the kill switch etc and clean replace as needed and see if that works.

Ground your solenoid to your battery neg. post.

Dan please elaborate on this. I am living a similar problem. To my knowledge my solenoid doesnt have a ground coming from it. Its post for power and fuse block, post to starter and wire connection to Yellow/green on mine. Ground how so? I have a ground wire from the wire bundle to the right of my solenoid that connects behind the solenoid. Maybe this is my issue.

The ground from the starter solenoid is the mounting bolt that holds it on a "panel" which also holds the fuse block & the R/R.

That panel in turn, gets its ground connection through its mounting bolts to the frame. Often that "torturous" ground path is compomised by corrosion & such, hence Dan's comment to simply run a new ground wire "directly" to that panel; which will also provide a better ground for the R/R as well.

[JStones]

could you possibly give me a step by step to do it correctly?

[DanTheMan]

Make a jumper wire with two ring terminals on it. Put one ring terminal under one of the solenoid mounting bolts and the other ring terminal under the neg. terminal bolt on the battery. Voila! Much better grounding, and the solenoid works again.

Got her running last night, bad battery box ground ran a separate ground from the solenoid. Thanks for all those who helped!!

[hikermikem]

Glad you got her running - recommend reading the stator papers now...
