I really doubt your coil is involved in this at all. There is no 12 volt anything going to your coil. In fact there is no 12 volt anything going to your whole ignition system.

To solve these types of problems you are going to have to use your meter and follow the wiring. Put your meter black lead on a good ground and leave it there. Take your red lead and start following the voltages:

1) 12 volts at the battery
2) 12 volts at the fuse input side
3) 12 volts at the fuse output side
4) 12 volts at the ignition switch input
5) switched 12 volts at the ingition switch output (switched on and off with the ignition switch)
6) 12 volts at the brake switch input side (ignition switch on)
7) 12 volts at the brake switch output side (when brakes are applied - also check to see if the brake light is lit up).
8) 12 volts at both sides of the starter solenoid small input wires (ignition on and brakes applied and brake light on).
9) One side of the solenoid input wires get grounded (goes to zero volts) when you push the start button.

This should not be a hard problem to solve. You just follow the wires with your meter. You have a wiring diagram. Yet for some reason, for reasons I can't begin to fathom, you refuse to do this. What can I say? You can lead a horse to water...

I'm pretty much done here unless you want to get with the program .

measure at the ignition switch input
then switched 12 volts at the ignition switch output (switched on and off with the ignition switch)
then 12 volts at the brake switch input side (ignition switch on). [At the ignition swith you have 4 wires (right?) What are their colors? One of those wires (probably red) should be 12 volts all the time since it comes from the output side of the fuse (which you already said has 12 volts on it). One of those wires (probably black) should also have 12 volts DC on it *only* when the ignition switch is on. When the ignition switch is off this same wire should have zero volts. Let's get this far first before getting muddled in too much other stuff . One step at a time... Do you measure 12 volts DC on a wire out of the ignition switch when on, and zero volts when the ignition switch is off?]

what does that mean the wires that come from the brake down to the harness?

when i measured the volts on the starter solenoid i got 12v for one post and the other read 0 volts. [There are four connection to the starter solenoid. Two big screw posts, and two little wires that come in through a connector. I'm assuming you are measuring the voltages on the two big screw posts to ground. One measures 12 volts and one measures zero volts. All this measurement says is that your starter solenoid isn't hooking up the battery to the starter motor - but we already know this because your starter isn't turning. There is no information here...

What about the small wires to the start solenoid? This is what you need to measure. Measure both of them on the 20 volt DC scale to ground. You need to measure them while the solenoid is hooked up to the harness, and attempting to start the quad (ignition on, brake on [and brake lit up], and start button pushed). If you have to, use a sewing pin to poke through the wire insulation to allow your meter to connect to the copper wire core. What do you measure? ]

this is on a gy6 for everyone thank you
