Kill switch wiring question

[bikejock]

I'm about to wire up my 4 stroke motor to the kill switch on my bike for an engine test. I got the green wire hooked up but whats weird is the kill switch in my kit came with a green wire and a red & yellow wire with a ring on the end. Should I just cut the ring off the end of the yellow and red and hook it up to the black wire? Or does it bolt on somewhere on the motor?

use your ohm-meter to see if the yellow wire is equal to the metal of the motor.
If not then it wants a "floating" kill switch.
A normal kill switch shorts one wire to chassis ground.

So the yellow & red wire with the ring on the end is the ground for the kill switch button? My engine is a 49cc HS 142F built in mid 2014. Also I noticed it didn't have the red on/off switch other HS motors have. That's not going to be a problem as long as I ground that yellow and red wire, right?

The directions that came with my kit seem to be a bit miss leading & somewhat confusing because it might be describing the wiring for a different motor. Who ever came up with these directions didn't do a good job. I've actually got more help at this forum and YouTube so far and go back to the directions for quick reference with some steps.

The wire with the ring connector gets bolted to the engine, it does supply the ground.

OK I hooked up that yellow and red wire with the ring on the end to a bolt on the transmission to avoid heat exposure from the engine so the engine doesn't melt the wire. Does this look OK?

You can bolt the ground to any screw on the engine itself; what you've done will work, but I recommend securing it out of sight.

Thanks for the help. This is for an engine test anyway. I'll probably move the wire so it's out of sight before the first ride. I'm going to take a Jerry can to the gas station tomorrow to fill her up for the first time. I want to test the engine, throttle & kill switch and make sure everything runs smoothly before hooking up the chain to the rear wheel.

Its going to be a few weeks before I take it on an actual test drive on the road. I'm still saving up for a special 3 piece wide crank axle so I can use my original bearings and chain ring for the pedal crank. The chain ring that came with my bike is better quality anyway. The stock chain ring didn't properly align with my rear sprocket for the pedal chain. The kit 3 piece crank feels like cheap quality anyway.

BikeJock,

Looks like you have a nice, clean bike there! Since you opened up a question about the kill switch, I'd like to ask a question about a little different situation. My "kit kill switch" is built into the throttle. I also have an after market horn switch which only would fit on the left handle bar. I would really prefer to have the horn on the right side and the kill switch on the left (just seems a little more natural to me) So, I thought of reversing the wiring, BUT..... I remember there being circuits wired into that kill switch?? Do any of you have any opinion as to whether the two momentary switches could be reversed? I know, I could just wire it up and try but, I'm curious about the circuitry I remember seeing behind that kill switch. Thanks, Jim

I would put the horn/light controls on the left. Weird I know but I don't think anyone makes left hand throttle/kill switches. I'm eventualy going to wire up a horn and some lights & turn signals to it so my controll for that stuff would have to be on the left.

My bike is a red with flames GT Dyno Deuce built in the late 90's & early 2000's incase you were wondering. The last Deuce was made in 2005 I think. Wish they still made them. You can see what it looks like before the motor on my profile page in albums. It's a hard to find bike to. I got lucky and found it on Craigslist for $250. I tried to find the black with flames version but the red was the only one I found that had all the original parts. Seen them with a 2 stroke but don't think anyone ever installed a 4 stroke on that bike (as far as I know)

Oh no, I wasn't suggesting I change the throttle to the left side..... Just send the kill switch wires to the horn and the horn wires to the coil. If I hadn't done such a good job of shrink wrapping the kill switch, connections, I would just try it, but I hate to mess with it now, so I probably will just keep the kill switch on the right side. More than anything, I have wondered .... why all of the electronics, in the kill switch?? (That made me question the idea of switching them)

I checked out your bike. That's tough looking bike! They are getting harder to find; Really good you could find one! I look forward to seeing it when finished.
