Don't get switch and relay mixed up, they are not same thing. Switch is simple with an input and an output. Relay has FOUR terminals, two inputs and two outputs. Don't get inputs & outputs mixed up OR connected. DO NOT connect input power directly to ground (greens). It will just blow up your battery, your fuses and start-switch. Take look at start-relay in junction-box:
Let's go over FOUR connections for start-relay:
1.
GROUND, yes tie all safety switch grounds together and connect to real GROUND. Such as chassis-ground on bike, or black/yellow wire that's connected to ground. TEST this connection with voltmeter and measure how much resistance (ohms) you have to frame and battery-negative terminal.
2.
+12v INPUT to COIL of relay. This activates relay and connects switch on other 2 terminals of relay. This is lower black wire that gets +12v from black/red wire coming from start-switch. It's normally un-powered UNTIL you push start-button.
3.
+12 INPUT to relay SWITCH. This is black wire and shares +12v INPUT from black/red wire from start-switch. Again, this is normally un-powered UNTIL you push start-button
4.
+12 OUTPUT from relay SWITCH. +12v power coming from black/red start-switch is then directed to yellow/red OUTPUT wire from junction box going to starter-solenoid which then powers starter.
To test this, you measure for +12v starting from battery. Basically trace flow of electricity to each component that needs it.
1. measure power at positive-terminal of battery.
What is this voltage?
2. measure power leaving battery going INTO ignition switch at white wire.
What is this voltage?
3. measure power leaving ignition switch at brown wire.
What is this voltage?
4. measure power entering junction box at brown wire.
What is this voltage?
5. measure power leaving junction box at red/green wire.
What is this voltage?
6. measure power entering right-hand controls at red/green wire.
What is this voltage?
7a. with start/stop switch ON, measure power leaving right-hand controls on red wire.
What is this voltage?
7b. with start/stop switch ON, measure power at red-wire at each ignition-coil terminal.
What is this voltage?
8. with start/top switch ON, measure power at red/green wire entering ignition-module.
What is this voltage?
9. with start/top switch ON, measure power at grey wire entering ignition-module
What is this voltage?
10. with start/top switch ON, start-button PUSHED, measure power leaving right-hand controls on black/red wire.
What is this voltage?
11. with start/top switch ON, start-button PUSHED, measure power entering junction-box at black/red wire.
What is this voltage?
12. with start/top switch ON, start-button PUSHED, measure power leaving junction-box at yellow/red wire.
What is this voltage?
13. with start/top switch ON, start-button PUSHED, measure power entering starter-solenoid at yellow/red wire.
What is this voltage?
This is all very simple, it's just like water flowing through garden hose to your sprinklers. Where +12v power stops, shows there's a problem upstream. Just like a clog in your garden hose. So take all those 14 measurements and post them here and your problem will jump out and be obvious like lion chewing on your leg.
