It seems that it is dead from the pink wire. I am definitely thinking this is the problem. This would also cut power to the IPG as well I believe which is why I am getting the same reading there. The problem now is that the 2 bolts under the ignition are stripped and I cannot get them off. The ignition has been replaced before I assume since I have two separate keys, one for ignition, and one for gas and trunk. As soon as I can get these two bolts out I can replace the diode. Does anyone know what the P/N is for the diode so I can go ahead and get it since I am leaving the house here in a little bit.

The bolts are not stripped. They are bolts that designed to break off on install.

Remove the top tripple clamp, which is easy, and knock them loose with a punch.
Buy a good part. There are many threads on cheap ignitions not working right out of the box.

If you are going to jump the wires with a new diode, it needs to drop the voltage to exactly 9.?v. Look around for the exact figure, as I don't remember. I will test mine, but I can't until tomorrow.

Can you further elaborate on how to get the bolts off. And also what you mean by jumping the diode. I was just going to replace the diode with a new one. Is that not the way to go or is it more difficult than I am thinking. I have not got in there to see yet. Top triple is removed. I was not buying a new ignition just replacing the diode if possible.

The diode takes power from the ignition, steps down the voltage to 9v, and sends it to the ecu. The computer runs on 12v, but it needs to see the 9v for the security system to let it work.

You could jump the ignition wire to the pink wire via a doide to step down the voltage. That's all the one on the bottom of the switch does. You could do it externally, in theory...

The trick is choosing the right diode.

If you were are just going to replace the switch, remove the bolts. To do this, take off the top clamp for easy access. Then take a punch and punch it counterclockwise to unscrew it. Once you knock it loose, it comes out pretty easy.

But if your bypassing it, there is no need to take out the switch.

I cannot get the bolts out, I tried drilling them out but my drill died after hardly getting anywhere. They are not punching out either so I may go the other route. Can you give me more details on jumping the ignition wire and where and how to do so, I may got this route. The triple is off the bike and everything is very accessible. Do you have an idea what diode to use I was hoping to get this done today but these bolts have help me back a lot.

After some research the 929's use a 2.2k resistor diode, would the 954 be the same.

not sure if they're the same on not.

The electrical part of the switch with the diode in it is only $45 or so. You won't need to change keys if you can get it by itself.

Well I got the bolts off and have access to the diode. Gonna take it up to radio shack tomorrow and get a new one, solder it in and hope for the best. I am 90% sure this is the problem and if it is not I will be ordering the IPG sensor and rotor tomorrow.

Looks like it is a 3.9V Zener Diode and no one local has them. I have to order it from radio shack and hope it is the right one. I am taking my diode up to radio shack to see if they have something comparable so I can get this thing running today. The part is $1.00 and will be here on Wednesday.

Just a little update. I have 3 different types of 3.9V Zener diodes (500mW, 1/2, and 1 watt) that will be here tomorrow. I also heard you can use a 2.2k resistor and my local radio shack has those in stock. So I am going to pick a few different types up tomorrow after work (1/2, 1/4, and 1/8 watt.) The goal is by 8:00 P.M. tomorrow night to have this thing running. Wish me luck guys I am going to need it.
