How to wire an ignition wire to my deck?

How do i wire up a atv ignition circuit?

• hi all how do i wire up a atv ignition circuit i have the battery fat + wire feeding the starter relay postive side of the relay a fat chuncky earth wire off the earth side of the relay down to the engine then off to the starter relay wire+ side to the igintion key out of the key way down to the cdi box as live feed in to the cdi i have earth in too to the cdi box then a feed out the cdi to the mag ,from the voltage regulator 3 yellow wires go to the mag and a green wire to earth and live to the battery ,the starter relay has two small wires coming off it one is fed from starter switch to the relay the other wire comes from the starter relay and a current comes out of this wire when you press the start button but where should it connect ? the starter relay does not click when the starter button is pressed but know the starter and relay work as ive shorted them out across the positve to negative side and the engine rotates

• Answer:

  Starter relay: Ok,,,lets try it this way and see if it's more clear Your starter relay has a total of 4 "wires"/terminals/connections. 2 are Small 2 are Large the 2 LARGE ones: 1 goes Directly to Battery. The Other goes directly to STARTER MOTOR. It does NOT matter which is which. It's a Single Pole Switch. It's Physical Function is exactly same as Touching Battery Wire Directly to Starter to make starter run,,, then moving wire away when ya want starter motor to quit running. --------------------------------------… The 2 SMALL ones: These are CONTROL WIRES that activate the Starter Relay,,, and cause it to Mechanically Switch/Connect the LARGE wires On & Off So,,,, One SMALL Wire comes FROM the Starter Button. You already have that one . When you Press the Start Button,,,You get 12V sent to Relay. Right? That is going to a COIL in the Relay,,,an Electromagnet. If You Check the OTHER SMALL wire,,,"coming Out " of the Relay...... You Will get 12V + . Because You are measuring Electricity > FROM the Starter Button >THRU the Coil >and OUT the end of the Coil wire. The Coil is just a Long wire wrapped around a spool So the 2 small wires are Actually Each End of the SAME wire. Ok,,,to Make the RELAY Operate and switch the BIG Wires Off/On....... You gotta turn that Coil into an Electromagnet. To do That,,,,,simply Connect the "Other Small Wire" Directly to GROUND. I realize that seems ODD,,,because it appears to be "Shorting the 12V OUT of the Relay directly to Ground" Actually,,it IS But that's how it Works. Long piece of wire,,,wrapped into a Coil. One end goes to (+) Other end goes to (-) And,,Voila!---You just made an Electromagnet. Light Bulbs are exact same way. One end of Filament goes to (+) Other goes to (-) Electric Motor,,,same way. All DC devices. So the 2 SMALL wires on the Relay... A)One gets 12V (+) from Starter Button B) Other one gets permanently connected to Ground (-) When ya Push Starter Button,,,that 12V+ creates a MAGNET which pulls the Relay's HEAVY DUTY Contacts together. Those BIG contacts deliver battery voltage to the Starter Motor. **** It DOES MATTER on the SMALL WIRES which is (+) from the Switch,,, and which is (-) connected to Ground. If they are connected "Reversed/backwards" that makes the Relay Work Backwards. Pressing the Starter Button would have OPPOSITE Effect. Relay would try to "OPEN THE CONTACTS" for the 2 Big Wires //////////////////////////////////////… 2 Big Wires: 1 to Battery 1 to Starter Does NOT matter which is which 2 SMALL wires on Relay: 1 to Starter Button 1 to GROUND It DOES matter which is which Connect everything. If the Relay doesnt work,,, Try reversing the 2 SMALL wires. If it Still doesnt work,,,Relay is Bad. (If You are getting 12V "Out" of the Relay,,,then the Coil obviously cannot be Burnt or have any internal connection fault) Sometimes the Electromagnet's Plunger which acts to mechanically move the BIG Wire's contacts will get Jammed. Thats why people tend to Bang on Relays when they quit working. They think it May Free a Jammed Magnetic Plunger,,,if that is the problem. Try it and see what happens One Small Wire to SWITCH Other small wire to Ground Simple as that //////////////////////////////////////… Edit: Here's a picture http://img374.imageshack.us/img374/326/solenoid28qt.jpg *This Pic shows "Starter Button" Switching On/Off to Ground On your ATV,,That is connected DIRECTLY to ground. It's one of the SmallWires on Your solenoid. The Push-Button Starter Switch ON YOUR ATV is , Between The Main Switch and the Solenoid Coil. On this pic You can start at the (+) on the Battery,,,and follow the SmallWire. *It goes to "Main Switch" *then to Solenoid Coil,,loops around&around to create the Coil *Same (+) wire thencomes OUT of the Solenoid Coil and goes to GROUND "when starter button is pushed" ........................ On your Bike,,the Start Button is placed Between Main Switch and Solenoid. Any "Safety-Disconnect Switches" are then placed BETWEEN So the Switch On sequence is; *Ignition Key/Main Switch ON *Then,,All Safety Switches must be "On",,everything they control in Correct position *That allows Juice through to Start Button---push it to energize the Solenoid. *The Waffle-looking square in the Pic is a "MovablePiston/Plunger" *When Start Button is Pushed,and coil is thus energized---creating the eletromagnet---that Piston/Plunger moves Toward the Big,Heavy Contacts and connects them to send power to Starter motor Main and Start Button
