Polaris 975 electrical issue - Try and solve this one?????????/

[ericbigbore]

my friend has a 2006 900 switchback and i seemed to be doing the same thing yours is doing .... what it came down to is he broke one of the motor mounts and the torq stops witch created more vibration than normal and the idle screw backed off witch made it idle really low and he couldnt get it into reverse..... just give it a try

All mounts are good and both slp torque stops are in and tight.

Eric,

WTH!!! LOL!!
I kinda hope your taking one for the 900 team this year!!
I don't really mean this........honest!!!!

BTW: Electrical BLOWS! JMHO!!

LMAO!!!

I've been trying to brainstorm ideas, but when it comes to electrical I'm like chit's on a boar!!!

Sorry!!

This might sound dumb but WTH!!!

Every electrical problem I have ever had on anything usually seems to revolve around a ground wire problem.
Maybe the perc system itself is grounding and dragging the rpm down likes its trying to shift itself constantly. I'd check the handlebars and the wires. Make sure the perc wire is not pinched and grounding out.

Again, electrical scares me!!!!!

I would say tps as well, but if they checked it then it's hard to say. It must have a short in the wiring harness then. my .02

I'll give them another look.

Low Idle will not let reverse work, and of course it could be the exhaust temp sender as mine was bad and screwed up idle mixture..low idle. Believe there are certain steps involved in setting curb idle speed..?

 

[NewfieBullet1973]

Question? Where is the TPS Sensor/harness? Is it in line with the throttle cable itself?

tps harness

that harness is very touchy, sometimes they will test fine and then the vibes of the motor running will kill it's signal.

 

[gonehuntnpowder]

I would bet tps, my 900 did a similar thing, wouldn't idle, no reverse, running very rich. Was tps. That is one of the few imputs to reverse engine for reverse.

At this point you really need to have a wiring diagram AND schematic. If Mountainhorse could upload one for us to see then some of the guys trained in logic circuits could try and help. It's all guesswork without the logic at this point. Hopefully he could chime in with some resources.

Thanks everyone I will keep you updated after I inatall the new tps harness.

I'm hoping he reads this but I think he gets slammed all of the time with questions.

Eric, do you know if Premier monitored the TPS voltage when they checked for codes? Also, I think I read somewhere that the idle switch on the flipper also causing no reverse. You could probably test it with a multimeter, should just be an open/closed type of switch. Also, on mine i could see where too much slack in the throttle cable will not allow the flipper to retract all the way, thus not allowing the switch to close. Might be something else to check while you wait for your TPS harness.

 

[CompFusion]

It seems like you have already checked a whole bunch of stuff. If a sled arrived to me in the shop with bad idle and no reverse (but works well at speed) the first things I would check would be for the presence of the 5X signal from the stator and then go through the baseline TPS setup. There is a video on how to do the TPS baseline on the site here .. it is shown with the TB assy removed but can easily be done on the sled. It does make a big dofference to the idle quality of these sleds.

 

[BIGGDAWG]

i know exactly where you are coming from mine did the same thing at the end of the season last year. the tp failed and was reading 3.5 volts at closed throttle so the sled wouldn't run unless above 1/2 throttle. i replaced the tp and reverse still didn't work and still no codes. i wasn't getting a tp code and it was bad i adjusted and set that darn tp so many times i can do it in my sleep and it still wouldnt work. thanks to some help on here i replaced the tp harness and bam it was fixed but that was after about 15 hours of work cause i replaced the stator too cause someone said it could be a problem. moral to the story start with the tp harness and sensor and make sure to do a sweep test on the tp sensor first if you are having problems with reverse.

TPS Harness

Can anyone get me the Part numbers for the TPS wiring harness...

I want to get a price on one for future reference, and maybe replace it just in case..

one for my 05 rmk 900 and my wifes 06 rmk 700..

thanks..

you have to look it up under FST and the part number is 2203165 $27.44 at babbitts online

Eric,
Had this same issue with my 900. TPS harness was OK, but the TPS itself was bad. It showed sweep with the tester but would not achieve the target 0.94V at idle with the tester. It had shifted internally and would not allow itself to achieve the proper set point. Make yourself a tester, it's easy and costs practically nothing (plans here on Snowest somewhere) and confirm. It will confirm the TPS for sure, it's a very simple test. The system requires that the TPS output voltage is at the 0.94V setting before it will allow PERC to work and also looks for that voltage for proper idle. If the TPS checks out then it will likely be the harness.
I know the frustration on this issue, been there done that. Go thru the tests, it will take the guess work out and get you to the solution.
Good luck.
Gary
