Default ECU Pink Wire 9V OR 12V?

For the Zerner Diode Pink wire at the ECU what is the volt reading? I am getting 12 V into the ECU and I can not find in the manual or of forums/google search if it's 9V to make the ECU happy or 12V.

Sorry if this has been answered millions of times.

Once I get my bike running I am going to make a full out " What to check post for all problems that can occur on these bikes and hopefully it will be a Sticky for noobs like me.

I believe it 9.3v.
If you search around this forum, you will find the answer including which resistor you need.
You won't find it in a manual, they like to keep that one a secret.

Thank You! This is most likely the source of no ignition / fuel pump. I am searching for the 9V battery bypass method now along with how to replace this diode if that fails.

Ok...Update she cranks...and the best sound to my ears! Instant Love! Now to order a whole new ignition as back up....Also how would one go about unlocking the gas cap if the key is broken off inside the ignition?

I took the old ignition off and tried to remove the broke portion of the key.....No luck...That thing is more stubborn them a fat kid eat cake. I bought a new ignition plus 2 keys with it off Ebay fr 35$!! But still gotta figure out the locked gas cap thing....I'm thinking about drilling the lock out.

careful drilling it out you dont get debris into the tank itself, i would do like mnguyen84 said and unscrew it before you try to drill it out

actually i just realized that even if he unscrewed the cap, it still won't come off because the locking thing camps to the inside of the tank.

Seeing as how the key is already inside, you should be able to rotate the locking system in order to unlock it. I suggest you use a hammer and something metal and pointy... hopefully by tapping the hammer on something, you can channel enough force to turn the key slot.

You can drain the fuel, undo the tank, flip it over take the pump off and use a good big pair of pliers to squeeze the prongs to release the cap and take it to any lock smith i had two bikes in here last week one had that problem the other had it in the ignition. It was only about 20 to rekey it. I dont recommend drilling it because then you will need to carry a screw driver around with you to open your gas tank. and you can drill to far/deep to easy. You can also go to a good honda dealer with your vin and registration and they can make you a key. I have had to do that with a customers bike in the past.
