Bike won't start

[Guest]

About a week ago bike got dropped over night. It was covered but it was very heavy rain that night. In the morning when I picked it up it didnt want to start.
When you hit the start button nothing happens, no starter solenoid click nothing.
If I jump starter solenoid it starts fine an runs.
Last night I had a couple mins to investigate. Took clutch safety switch apart and cleaned it still nothing.
Took right hand control apart cleaned all connections still nothing.

Because the bike runs and shuts off with kill switch this lets me to believe I have a problem in the harness somewhere.

All fuses are good by the way.

Any input which part to tear apart next would be appreciated. I just wanted to confirm im on the right track and not overlooking something obvious.

Do you mean, by shorting the big terminals together (with screwdriver or something) ??? or by using jumper wire from battery positive to actually trigger solenoid???

[Dodik]

jumping with screwdriver across solenoid itself,
the solenoid is a year old model number s5049 meant for older FORDs

[tom203]

Can you use a 12 volt positive jumper to actually trigger solenoid- neutral PLEASE!

Tap on the selinoid with a wrench kinda hard to see if it gets unstuck...if not, then replace it.. Tractor Supply has them..and many riding lawn mowers use the same set up. Some here have stated they got one at Lowes for around 9 bucks.

[Dodik]

ill try 12v to trigger tonight,
Its worth a try I guess to tap it. In NYC there are no tractor supply and Lowes/HD do not carry riding mover parts unfortunately.

Take it with you to any local lawn mower sales place...its a pretty generic selinoid. Small engine repair places, landscaping equipment sales place...whatever. You get the idea.

yes i did it last year that why i have automotive solenoid, spent whole day trying to find one
there are barely any grass in the city, you have a higher chance of seeing Wes Cooley riding pristine 82 Katana with 89 GSXR parts and talking on the cellphone to pops yoshimura than finding a tractor / lawn equipment parts in the goddamn city. lol
I guess i have to check solenoid if it is bad then i know what to do.

I have a bike ( the 77 750 ) that has a tempermental kill switch. Sometimes i have to sanp it back and forth if I " forget" that its weak and accidentally switch it off.


Maybe try snapping it on and off a bunch and then try the starter button..Do it a few times and if it hits just NEVER hit the kill switch again..or get in there and find out why its sticky.

[Dodik]

if it was a kill switch it would not run once jumped across solenoid, plus i already cleaned connections in it last night.
So far I know that solenoid gets the voltage to it but is not sending it across. This could be to things
a. bad solenoid
b. open in the start button wiring.

[chuck hahn]

Follow the two wires to the start button down to to where they plug in and use a jumper wire to see if it cranks maybe?

[Dodik]

borrowed another solenoid from a buddy last night still no bueno,
Now im positive its a harness issue, taking the bike to my folks garage tonight was planning on painting tins this saturday. i guess while paint dries I can tackle this and fix my rear brake not lighting the bulb at the same time.

I had an issue like this after changing my handlebars, turns out I had stretched one of the wires from the starter button. I followed the wires with my fingers and could feel the break. It was near the neck of the frame. I fixed it by adding spade connectors and tapeing it back up.

[Dodik]

turned out it was clutch switch, just bypassed it and all good now. Thanks all for the help.
Now onto diagnosing my rear brake light switch
