Does any one know how to check a TPS on the newer snowmobiles. I know its done with a digital multi-meter but thats all. I have a 2000 XCR 800 and would really appreciate any info you might have. Method, readings ect. I have noticed that several of you guys are "in" with dealers. Maybe they would tell you how. Thanks in advance........ Hotrod

The service manual will tell you the voltage that the TPS should be adjusted to. Polaris sells a service tool that uses a 9 volt battery to check the TPS. The voltage output is the way the cdi knows what the throttle posistion is. if it is not correct the CDI will think not give the right timing curve that matches the throttle posistion.
I would check the service manual some engines are set differently than others, The 800 triple is set differently than the 800 twin.
I hope this helps.

thanks for the replies. I will be making a tester up this weekend. Does any one know the voltage at WOT for the XCR800. That was an excellent site you sent me to ZR5. It was mostly for XCs though. Do you know of one like it for XCRs.

Testers made and ready to test. I dont want to afford a service manual right now. Anyone got one or knows someone with one? I would really appreciate the info on what voltage and what throttle position to test at.
