Kill Switch

[Angel]

so..putting away any switch, if I add one more wire on top of the sparkplug and while the engine is running I touch the end of that wire to the frame, the engine will stop without any damange?

So why cant a momentary switch be wired inline with one end attached to the spark plug(s) and the other to ground. Isnt that how a briggs works essentially. Most likely will have to hold it down.

I'm 90% they still ground out to the block.

Theoretically, yes. But I wouldn't.

I re-read my last post and I'm not sure why I said to use a 3 pole switch. Just splice a wire into the red one coming from the stator and send it to the green on your key switch and ground the black and white wire. ( All this is assuming that red is hot)

Same idea but a little simpler.

If I understand you correctly the easiest way to so this is to ground the source from the stator , killing the spark. The best solution would be to have a 3 pole switch with a input, and 2 outputs. Connect one output inline with the ignition system and the other to the ground/engine.

I don't think I quite understand your explanation of your key switch, there should be one wire that stays the same when you turn the key.

That is what I have. A simple ignition switch http://www.banggood.com/Wholesale-I...-Bike-50cc-70cc-90cc-110cc-150cc-p-49848.html

I just did a bit of searching and found this

Earlier in this thread posted the Giovanni published wiring diagram as scanned from their manual. Like most published diagrams it had errors in it. I fixed those errors in this picture (click on it to expand): Note how one of the errors had the starter button labeled as the ignition switch, and the actual ignition switch was labeled as just "switch".

Your ignition switch should have 4 wires on it.

Red: Fused 12 volt power
Blk: Switched, fused 12 volt power
Grn: Ground
Blk/Wht: Kill Switch connection to CDI

The ignition switch is actually two switches ganged together on a common shaft:

When the Ignition Switch is off:

Switch 1: (Red and Black) are not connected
Switch 2: (Grn and Blk/Wht are shorted together

When the ignition switch is on:

Switch 1: (Red and Black) are shorted together
Switch 2: (Grn and Blk/Wht) are not connected.

It seems to coincide with what you were explaining with your switch. Maybe try looking at this wiring diagram. Your ignition system looks to be much simpler and you could probably just use one of the circuits in the switch.

yep, you are awesome, this is exactly type of switch I have, now I just need to find out how to skip connections to CDI in diagram you gave me. So now I can ignore black and red wire, should be useful when i'll add something such as lights. Now we know I need just blk/white and green wire. But it seems like everyone knows how engines electrical system works but me. I think i'll be done if you explain me again this idea

Just splice a wire into the red one coming from the stator and send it to the green on your key switch and ground the black and white wire.

You told me to attach one more wire to the red wire from stator. but white one should remain connected?

 

[exenos]

Are there lights, electric start on this engine?

 

[Angel]

obviously there are not. Come on it took me 2 days to find out how to connect that switch. Lights and electric start are SF

 

[exenos]

No it is not obvious. If I search "Romanian Mobra" I get a Romanian motorcycle. I have no way of knowing if this engine is still on the bike, or if you put it on a kart and kept the lights from the motorcycle or ditched them.

Since there are no accessory's then just do as I suggested 6 posts up and use one circuit from the key switch to ground the hot wire coming form the stator to the chassis.

 

[Angel]

Let me know if I got it: green wire to the chassis; one wire to the red wire from stator sending to black/white wire from the switch. isn't it?

 

[exenos]

This should work but there's no guarantee.

 

[Angel]

Thanks man , but if it doesn't work is there any risk to damange my engine or to get shocked?

 

[exenos]

It just simply wont turn off when you turn the key and the only way you could shock your self is if you don't insulate the splice properly. If you want to be 100% sure wait around until someone else chimes in with what they think.

 

[Angel]

I'll wait. Thanks again!
