I am not sure this is the problem. I am just trying to narrow down and rule out possible problems. This is my first sled with a TPS, so i would like more info on how they work. I have done numerous searches and can't find any good info.sorry cant be more of help mine is a 1995 650 efirxl r u shure this is the problem there is a way to test them at idle and full rpms with a tester a guy has one on youtube im shure someone on here can help keep us posted to see what u find out:dunno:
Thanks BC_Dan, I will try to test or get this tested and let you know what I find. I am a person that likes to know how things work and what they do, so I am still wanting more info on the TPS and how it functions with the motor.The TPS should be factory set and not require adjustment unless it has been removed or replaced. There is a factory test kit, Polaris part no. 2201519, but there are some home remedies using parts from Radio Shack. Basically, you input 5.0 volts into the tps and measure voltage coming out. At wide open throttle, voltage out should be 4.0v to 4.2v. You will need a good digital meter to test. After the voltage is set to spec, use an analog meter to determine if there are dead spots in the TPS. You can have proper voltage at full throttle, but as you open the throttle, the analog gauge will show if you have bad spots in the TPS.
If you take a trip over to www.snowest.com and search there, there are diagrams and part numbers on how to build your own tester.
If you have a good relationship with your dealer, they may throw their tester on your sled for free. It's a 5 minute process, especially on the Edge sleds.
XC, it didn't look like you had your question answered to your satisfaction. The TPS is simply a potentiometer (or variable resistor). It's exactly the same concept as a dimmer switch on your living room lights: as you move the dimmer more open, the lights brighten, and as you close it, the lights dim, all in a very smooth, linear way.Thanks BC_Dan, I will try to test or get this tested and let you know what I find.
