Coil Voltage to Tachometer

I've run a separate wire to isolate the harness and even taken a reading directly from the black lead of the coil and continually come up with the higher voltage.
Anyone had / know of this problem and have a solution? Thanks

I'm pretty sure this manual covers your bike. There are others listed. Kawasaki manuals have a model application chart on the back cover, so make sure your model is included on the list.

That wouldn't be the first Clymer manual with a typo. It should say 12-14 volts. The tach picks up it's signal directly from the coil.
Good luck, Paul

Kawasaki Cam Cap Torque
Cam Cap Holes Stripped
The torque for the bolts should be 66 INCH Pounds(8 foot pounds), not 12 ft pounds. It's incorrect in the factory manual, and probably wrong for the Haynes, Clymer, and Chilton manuals too.
Out of curiosity Mike, how did you know the torque specs are wrong in the factory (and Chilton) manuals? From 12 ft lbs to 5.5 is pretty significant amount....
I found that out at KZrider.com. Somebody a ways back was complaining about stripped camshaft bearing cap bolts, and how his seemed to be over torqued. If you can find "Kopcicle" here on this forum, he can probably confirm the lower torque limit.
Another torque change is the two M6 x 1 cylinder head bolts , going from 104 INCH pounds to 94 INCH pounds.

All of the pros around here say no more than 9 ft/lbs for the cam cap bolts. My butt is still sore from when I suggested that the manual knows best. I got my mind right now.

I believe about 104 inch-pounds is right for the camshaft cap bolts (don't exceed this) but the cam cover itself: I use a lot less, more like 60 - 70 Inch Pounds to keep from crushing the gasket.

With that in mind, what do you make of the 9 to 10 volts I'm seeing from the coils - I've tried both? Is that measured as DC or AC with the meter? I appreciate your time.

Replaced the Tach and it shows no RPM. Thanks

This is one of those things that is lots easier to repair/troubleshoot if you understand what it is supposed to be doing.
Think of the tachometer as a "frequency" meter. Frequency is measured in cycles-per-second or "hertz" or "HZ"
In order for the tachometer to see the frequency that the coil fires, it needs two things:
1). A good solid (+) voltage signal, usually switched with the ignition key... key on=voltage (measured or referenced) to ground. A good thing!
2). A pulsating (-) that is generated by the points on older motors or the electronic ignition on "newer" models.
This "pulsating" (-) is found at the (-) terminal of the coil weather generated by points or electronic ignition.
If you have a more up-scale DVOM you might even have a HZ setting on your meter.
Hook your tachometer feed cables up to your DVOM, set it to read HZ and start the motor. If you see 16.67 hz or so at idle, AND it changes to a higher number as you rev the motor, your tach circuit operates as it should, and your trouble is in your tach. If you don't get a hz reading, you have a wiring issue, or the wrong wires.
Hope this helps, and good luck with your tach. Paul

keep in mind, I'm not a Kawasaki specialist, I don't have the FSM sitting in front of me, so I can't quote wire colors or anything. I'm just a knuckle draggin' electrician with a little bit of theoretical knowledge doing my best to keep a power plant running!
