CB500 kill switch
« on: June 02, 2014, 07:49:26 PM »
I need some help with the kill switch on a 500 as I'm having trouble getting the one in a left hand control to work properly. I got this switch from Dime City a while ago. It consists of a simple push button that, when pressed, makes contact. Can someone tell me if this is the same way the stock kill switch works? The reason I ask is because a continuity test indicates that this switch is working opposite of how I need it to (motor would run while pressing the switch but die when it's released). I know I am supposed to use switched power (black) and the black/white wire from the coils but I never even got to wiring it up because it didn't look like it was going to work.

For the stock sw. as you said has a black power wire that gets hot when you turn the key on then with the kill in the run position a set of contacts close and hands power over to the black/white wire. Then the black/white wire goes to the coil giving one coil power then a short jumper comes off that coil and goes to the other coil.
 I think what you have is a momentary push button and that will not work as you found out. Think about your light sw. at your house you have to manually flip the switch both ways one way on other way off. I just looked at DCC site and they have quite a few switches in all flavors. Can you post a link to the one you bought?

Hey thanks for explaining the way you did. I'm more visual so wrapping my head around electronics has been a difficult part of this project for me. Here's the switch I bought.



By your explanation...the kill switch on this control is not at all like a light switch or even the high beam switch on this control. You're saying that I need one that is designed like this?

Chris - I had that switch. Dump it. Piece of #$%* all the way thru. You'll need relays to make it work. The 3-way thumb switch WONT allow you to operate a "Kill" mode. Best you'll get is: in bottom position "no start", first position, start with no light, and top position runs with lighting. The only thing it's decent for is being able to wire the bike to start with headlight off. The rest of it, crap, crap, crap. And it's plastic, where these listed below are metal frames. Nicer feel all the way around.

And this on the right

I've got the left on my 550, but because I'm running my MotoGadget m-unit, a simple push button switch acts both as a start (one push) and a kill (two pushes).

Well that's a bummer. I had seen the one's through Devin but it was the day after I ordered this one from DCC. As I'm sure you gathered from talking last night, I'm feeling a tad frustrated with the project right now. Probably has more to do with the chaos of the last week of school than anything else. I just feel like there are a lot of issues that need to be addressed but I'm just not sure how to prioritize them (thanks for the guidance last night). At this point, I think I'd like to be able to ride it around town this summer and have fun with it and continue to get a vision of what I want it to look like and then, this fall, plan on taking it off the road for an extended rehab.

Fear not, Valiant Prince. I've blown my budgets time and again by buying and re-buying the same parts.

I like the guys at DCC, but in the end, they peddle much of the same crap as everybody else. They're better at customer service than many, they're more humble than most, and they generally try to do good things and treat people well. But for "generic" parts, the brands that most carry are still crap.

I've moved away from inexpensive (because it doesn't work, doesn't last, or doesn't fit) to more expensive stuff because it works, fits, lasts, and I spend only once. I'm pretty darn impressed with MotoGadget stuff from switches to gauges to controllers. Simple, efficient, and flexible. And small. Makes it easier to maintain a cleaner looking bike.

Priorities should always be:
1. Anything to do with tires, brakes and suspension. Safety first
2. Reliability - electrical, charging and fuel
3. Comfort - if it hurts to ride, you won't.
4. Style - first thing everyone sees, but the last thing that matters. You are well on your way already with the last one. Bike looks really clean and tidy. Now make sure it's safe, reliable and fun.

Easy.
