Hey there guys...
I'm having some trouble getting accurate readings out of my new(actually second hand) PET2100
The problem is the thing never came with any instructions or a cable to connect to anything..??
Anyway i went ahead and got some cable(nondescript wire) doubled it up wrapped it around a plug wire, = shit readings..??
Wrapped it around 3 plug wires (tinytach style) = shit readings..??
Tried wrapping it at both ends single and triple plug wire options = shit readings..??
I put the other ends of the wire into the two small holes that stick out the side of the tach..??
Is that right..?? can't see anywhere else to put it..!!
By shit readings all i'm getting is a third of whats actually happening i.e max rpm is around 2350.. idle shows 400 or so..??
I have it set to 23 46 (2smoke )..???
help me out guys.. what type of wire do i need to use..???
He He He... if the circus come back to town.. this clown is still getting left behind..

From Randy at WatCon.
Also, try wrapping your wire around all three plug wires in back, right where they come out of your electrical box. And yes, you have the wire in the right spot on the tach itself.
Simplified 2100DX instructions.
Thank you for the purchase of a Pulse Pet-2100DX digital tachometer.
I've put together a "Quick Start" manual to help the first time user get up and running in no time.
The whole key to the operation of this tachometer is the "MODE" button.
To change the setting example, from 2-stroke 2 cylinder (P22:44) to 2-stroke 3 cylinder (P23:46). Press the "MODE" button until only numbers appear in the display, such as P22:42 or P23:46.
To change to different types of motors press the "SET" button.
You will want it to read P22:44 for 2-stroke twin cylinder, most 2-stroke 3 cylinder triples use the 23:46 mode
21:42 = Single cylinder
22:44 = Twin cylinder.
23:46 = Triple cylinder.
Using the basic tachometer
Once you have clipped the antenna lead to a spark plug wire and brought up the correct mode required using the directions above, you are now ready to monitor running and peak rpm.
You may also measure Rpm's by simply holding the unit near the spark plug wire.
Remember: This tachometer is “water resistant” not completely waterproof and it is your responsibility to protect your investment. Please protect it from submersion if possible. We recommend using clear plastic “shipping tape” to attach it to your watercraft. The best method to remove tape adhesive from the face is “WD-40”, other chemicals might damage the case.
Using the hour meter.
This unit has a built in hour-meter for both total and temporary time. Press the mode button to display the hour-meter. You can toggle between total and temporary time by pressing the "SET" button. You can also chart the temporary time by pressing both the "MODE" and the "SET" button at the same time. This can be a very important feature for breaking in race motors or by knowing the actual running time on the motor.
Using the Max RPM recall feature
Once you have made a run, you can recall the maximum RPM recorded.
Again, press the "MODE" button until a small black mark appears on the top left side of the display. The highest RPM will appear in the display. To clear this for the next run, press the "SET" button on the right side of the tach. On certain motors, when the engine is first fired, the MAX RPM may be extremely high and inaccurate, push the "SET" button to clear this out.
Using The "TWIN MAX" RPM Feature
You can compare both your MAX RPM from the last run and your current RPM, fide by side at the same time. Press the "MODE" button until you see Twin Displays. The left number is your MAX RPM and the right number is your current RPM. You need to take this number times 100 to obtain actual RPM. For example 80 actual is 8,000 RPM. To clear this MAX RPM, just hit the “SET” button. The dual mode will not read in 10 rpm increments and isn’t recommended for tuning purposes.

You shouldn't have to double up the tach wire a single piece will do the trick.
Just make about three turns around one of the wires I use the No.2 wire then run it up to the tack go in the bottom of one whole and back through the top of the next you only need just a little bit coming back out the bottom 1/4 inch or so and you should be good. Using the instructions from the last post it should be ready to go.

So for the wire...??
Just use anything.. OR do i want low loss signal cable..??(Hmmmmm that'd stop the signal pick up too..??)
What about the wire that comes with an fm stereo for the antenna..??
Any special thickness (other than my heid..??)
OK..... to jetski-mobile,,, Batman...!!!!! (imagine the theme tune here)..

Run a common piece of copper wire from the PET back to the electrical box. Solder the end of the wire to the alligator clip, then clip it to the #2 plug wire by the box.

I used the black, i believe 18 gauge wire from walmart. Its in the auto department near the fuses $3. Its the same size as pets stock wire.
I wrapped 3 times around each plug wire near the electrical box. Its a bit overkill. I get the same readings as just hooking the stock pet wire and alligator clip up to #2 wire.
I only went with the other wire because the pet wire doesnt reach any further than the glove box lid.

That exactly the info i was looking for...!!!
I'll get myself some 18g wire tomorrow...
Once again thanks

You guys that got it to work on the #2 plug wire only, must be livin right, I tried it on my 05 GP1300R and 05 XLT1200, no go, then I wrapped it around all 3 plug wires and it works perfect, go figure........
