I Have A 2005 Xcsp 700 With 1443 Miles On It And The Perc Has Abruptly Quit. The Switch Acts Like It Has No Current Going To It, And Does Nothing When You Push The Button Or Even Hold It. When It Did Work, You Could Hold The Button In For A Lenght Of Time And It Would Change The Ignition Timing For High Altitude Riding. This Change Was Shown By The Speed At Which The Reverse Light Flashed. Now This Feature Does Not Work As Well. My Dealer In Western Maryland Suggested That The Problem May Be In The Cdi Box. Does Any One Have Any Insight On This Problem? For What It Is Worth, The Sled Is Bone Stock And The Idle Is At Factory Settings. Another Problem That The Sled Has Is The Temp Light Flashes When Riding At High Speed For A Short To Moderate Length Of Time. Once Again, The Sled Is Bone Stock Running At Factory Settings, Jets And Clutching. I Run 93 Octane Gas With A Bit Of Dry Gas Added And I Run With The Switch In The Premium Setting. Moving The Switch To Regular Does Not Fix The Problem. Any Suggestions? Thanks.

Anyone With Any Help Or Suggestions? Thanks

Just got done with a weekend ride and had the ability to take parts of my friends 2004 700 classic. I swaped CDI boxes, DET boxes, push button control units and none of this caused my reverse to work. Funny enough, all of these parts must be functional because they worked just fine on the 2004 700 classic, allowing the reverse to work on this sled no matter what part we swaped. Any ideas or help would be great. Thanks

I have been selling polaris product for nine years now and to the best of my recolection I have only seen one perc not work. Two weeks later the sled would not run anymore. Problem was the stator. You should be able to get what the meter readings should be from a service manual before you put in a new stator.

What meter reading are you talking about? How difficult is the stator to get to and remove? Thanks for the help so far. FYI: I am leaving for Quebecc Canada at the end of Feb. for a weeks ride and plan to go 1100-1300 miles. I am trying to fix the PERC before this trip

There is about 6 wires coming out of the stator. You wouls need a service manual to tell you what resistance you should have between what wires. The stator is located behind the recoil housing. Not thatdifficult to get at. It is worth about $4-500 so you don't really want to change it if you don't have to. Send me an email at johnmorin63@hotmail.com and I might be able to email you that section of the service manual.

Good luck

I think you'd be remiss in not looking at and perhaps jumping the switch on the handlebar. I have found some of Polaris' switches to be "weak points" in otherwise excellent systems. Solid state electronics are so very reliable that something that works and has such low miles (hours of use) is very unlikely to act up IME. I would not consider a fault in the electronics to be very high on the list of possibles except if the engine had experienced a nearly catastrophic event where heat or hard impact may have affected things. The weakest link in that whole system is the switch on the handle bars. Make that prove itself first, and go from there if necessary.

I have swaped out the contol unit, with the switch in it, from another functional 700 and that did not fix the problem. Any other thoughts? Thanks

Missed that part in your original post. My apologies.

So you've done just about everything short of trying the stator. It appears that the stator is single unit part; at least that's how it's sold.

I am not familiar firsthand with the stators on the PERC machines so I don't know if they have a PERC component on them which could fail without taking out the rest of the stator. My gut suggests that the stator fails as a unit or not at all. Therefore, I still think it might be worth looking at a few more things.

I would be interested in the wiring; if the wiring harness has any flaws in it which might be a problem. Also, whether something like the voltage regulator is doing its job correctly. (They are one component that seems to fail gradually sometimes.) Check to see what your line voltage is. It should be 13.5 (AC without electric start) or less at idle; no more than that at higher RPM. Perhaps that is critical.

You might also try disconnecting any instruments in the dash which are related to functions of the PERC or other systems in the same control. I rather doubt they might interfere, but you never know and it's an easy thing to check.

It seems like a bit of time with a volt-ohm meter might be in order.

Thank you for your information. I am going to take some Ohms readings from the wires coming out of the stator and see what is what.

There are two pieces of information that would be nice to have about PERC in a general information sort of way - and could be helpful to you in sorting this out.

First, is the stator wound with a single ignition generating coil or is there "two-in-one" - so a separate coil for forward and another for reverse? (There may also be a third coil within the unit which makes power for the chassis components.) (If the ignition is a two in one, then the reverse could give up separate from the primary/forward section; if they're one, then I don't think you'd be able to run the motor at all.)

The second question I wonder about is whether there is a specific voltage requirement in order to trigger PERC and other things. (That's why I suggested the voltage regulator as a possibility; I don't know if that matters to PERC.) It might also cause the activation of a safety device such as a breaker or fuse - though I haven't seen one in the diagrams. (You might check the owner's manual. That should say if one exists.)

I'll bet if you know the right question to ask, and can get an answer to that, you'll find the problem.
