New member here needs help,I have a 99'Grizzly and I'm not getting any fire to the coil,Checked orange wire from cdi to coil it has contunity,checked plug ,battery,starter,It had a new stator put in about 5 months ago,It ran fine until sunday I was riding it and i got off and put it in neutral and let it idle about a minute and it just died, it started back up twice and immediately died both times now it wont do anything. any help would be appreciated thanks.

Check the connections to the stator.
Also check the wire clustger routing te ensure that it is not abraded at some low radius bend or a sharp edge... ...

Do you mean the conections inside the case on the stator or where they plug into the harness. I thought it may be a wire broke somewhere also but I took the whole wiring harness off the bike and removed all the sheathing,No bad wires.

You may need to check both ends, but I would certainly start with the external connections. You don't need to remove it to test the internal connections, but you will need a multimeter to measure them.
I have not worked on the internals of a 99 model Grizz, but I believe the following is true for all model years from the older models to current. It doesn’t appear that Yamaha made changes to this area for many years.
There are 3 separate elements contained in the stator wiring cluster, in 2 separate Molex style polarized and keyed connectors.
Charging system
Ignition triggering
Direction of engine rotation
You should have 3 wires all in the same connector that are the same color or are very close to the same, (most likely white). Those are the charging system and should lead to the rectifier/regulator module. The resistance (ohm value) between any one of the 3 to any other one of the 3, should be “very†close to equal.
There should be 2 other wire “pairs†(4 total wires) of additional wires that belong to the "ignition trigger" and the "direction of rotation" sensors. You "might" need to switch your meter over to the “Diode Test†mode, (it depends on your meter), to test these, I would imagine they are "Hall Effect" transistors. Hall Effect devices will “threshold trigger†in proximity of a sufficient magnetic field (special area on the Rotor).
As you rotate the crank slowly, you should see a change on your multimeter at the connectors. Assuming, you have the correct wire pair.
The CDI will also fail to trigger (lock-out) the ignition if it cannot determine the direction of rotation, (it will assume the worse). Test this related pair of wires in the same way, it is also controlled by a Hall Effect device. (If the ignition was allowed to fire while the engine rotation is reversed, the “one-way†bearings could be quickly destroyed (along with a few other sensitive components.)

Thanks Grizzhopper I'll check that stuff out tonight when I get home.

IChecked the wires coming out of the stator and one one pair of wires I got 109 volts,Is that too much voltage? What I need is a wiring diagram for a 99 600 do you know where I can get one?
