I think 'tizzy told me to buy one too.

Be careful when removing/installing the nut that holds the cable onto the starter.
You *do not* want the stud to turn when you turn the nut.

Alright, bought myself a little automotive voltage tester.


The solenoid is getting power from the battery.



However, the starter is not getting power from the solenoid.



So I am guessing the problem is the solenoid is out. Yes?

The solenoid is a normally 'open' circuit in that the device only passes current when the low-current (2x wires in the white connector) supply power to a small electro-magnet which closes the contacts and makes the solenoid a 'closed' circuit.  At that point, the batter has a path to power the starter motor.  If the solenoid is getting the low-current signal voltage from the 'start' button and the bike still isn't starting then yes...your solenoid is fried.

However, if the test you described was done without the low-current circuit of the solenoid powered up, then the test results aren't valid.

Check to see if the solenoid is getting 12V power through the two wires in the white connector when you have the key on and the 'START' button depressed.

How do I test the white connector?

Stick the volt meter prong on the fitting and then hit the start button?

Remove the white connector and put both test leads from your meter into the plug (one per side).  Set the meter to DC voltage.  Turn the key on.  Hit the 'START' button.  Check the meter's readings.  They should mirror the battery readings within 0.1-0.5 volts DC.

Mr Stuart is the man!

He guided me through and I found the problem.

solenoid is bad.

however, since I am a moron and coudln't figure out the multimeter.......I fried a fuse.


must have had the setting wrong on the device, as when I hit the button on the starter with the prongs in the female end, POP goes the fuse box. But the good news is it had a reading before that.

Therefore, I know the line had juice.


Just ordered the yamaha starter solenoid from CA-Cycleworks

Seems to be a hard part to find locally

You fixed it because you procured a device to see electrons. ;D

Um........I need someone to teach me how to use that make the beast with two backsing thing!!!

I fried two fuses with it!!!


the only reason I know Stu's idea worked is because it registered on the device and then POP! blew a fuse

We have a DESMOHIO maintenance day on Sunday; going to bring this device with a notepad so someone can teach me how to use it!!!

what can I say........

1. doctor's son: my dad tried to install a new toilet when I was a kid. He tightened the base bolts too much and cracked the porcelain!
2. I am a finance guy. I live my life in excel, bank statements, hedging, etc. I can guide anyone there!

maybe time to learn how your bike works... ;D

Well, I know how the starting system works now  [thumbsup]

I was greeted at lunch today with a nice package from CA-Cycleworks containing my new relay.

15min install

hook up battery


Fired right up!



I want to think Duck Stew for all of his help on this. He spent a lot of time PMing me helping my un-mechanical self diagnosis and test certain connections to isolate the problem.

It worked. I did my first major "repair" on any of my bikes or in fact.....at any time in my life.

Also, thanks to Tizzy' and Ducpainter as they also gave me pointers.


Thanks everyone!
