- I provide quick and easy diagnosis of a no power no start condition on a Polaris Ranger. This is basic diag knowledge and works for almost all Polaris models with sure power control.
Good information. My 06 Ranger 500 had an issue with not shifting into turf mode. Replacement of this part cured the problem. It was an expensive part at $475
Thanks for taking the time to shoot this video and share your knowledge of this part of the electrical system!

Great video! Gave me a lot of information
Awesome video thank you
Thanks, big help!!!
Love your video super informative I'm learning a lot I'm struggling with a 500 EFI that's an 08 that I have multiple codes saying I have multiple broken wires and or short to ground I've replaced the entire wiring harness and still showing the same codes wondering if the PDM could be the source of my problems but I'm afraid to just replace it since it will start and run but runs poorly any help or advice would be super appreciated thanks
I have a 2006 Polaris Ranger 500 which has had a total dead condition. I traced it back to the PDM just like you did except I found NO corrosion,NO burned or darkened connections,all wires looked & tested good when unplugged? So what was the problem? Well I cleaned & coated all connections with dialectic grease plugged them in & it works fine generally for six months or so then all of a sudden a dead condition again! I repeated what I did previously & it works again just fine. This had happened 4-5 times in the last 15 years. I showed my wife what to do in case it goes dead when I am not around so she isn’t stranded. My point here is I wonder how many times the PDM has been replaced when there was nothing wrong with it? Even checked each wire for higher resistance values with an Ohm meter,this may have shown a partial break or internal corrosion but NOPE. It seems to be a lose fitting plug connector in the plug even tho all look & test good? So to anyone with this problem disconnect the plugs from the PDM,test as done in this video then clean,apply some dialectic grease to connecting points,plug them in & try to start again!
Good video
Thank you
Thanks for the video. My 2015 570 was started just fine, ran for about 30 seconds and suddenly went totally dead. No power, no start, no idea where to start. Looking forward to walking it down using your suggestions.
Your very welcome. The 570 uses a different electrical system. Polaris stopped using the PDM system in 2007. Hopefully though my video is giving you basic insight of where to start. Don't for get to subscribe for more great content. Currently building my 570 video library, there will be more for your machine.
@@montemania198210 I have a 570 no power to kill switch or ignition switch if I jump the solenoid it turns over. Any suggestions?
if you have a few minutes to chat, spent a lot of time trying to help a buddy out...2012 polaris ranger.
we been testing, testing, testing...scratching our heads...we have a crank no start....fuel pump does not prime, and no spark.
everything else works
all fuses and relays pass, grounds test appear good.
leaning towards ecu/ecm/pcm...what ever polaris decides to call there computer. but before we go spend that chunk of change. is there something you know of that will create the ignition not to do there job? again good crank- No fuel pum-No spark.
I’m having the exact same problem on the same model. No fix yet
Good day. Was watching your 570 videos for top end build. Funny i found this one as well. I got a 06 700xp in the yard. It overcharges and shots off.(shoots up to 20 volts) After i unplug the pdu and pluge it back in it will start again. One of the yellow into the pdu is burned and the main red to the battery is burned. I fully charged the battery and unpluged my stator. It will run no problem. Well ran it for about 10 min. So guess i asking if its a stator problem or pdu or both.
Definitely a PDM failure. Now that being said I would also suspect a failed stator as well. PDM tends to take stator out. I will be posting a video on upgrading the system to the newer non-PDM version. Watch for it next month.
I have a Polaris sportsman long story short I have replaced stator battery and ecm after my bike quite turning on I can’t seem to figure out why the ecm keeps getting very hot, also the ecm has previously been relocated into the front storage compartment would that be an issue? Any help would be very appreciated
Great Video. I have a 06 Ranger 700 XP. I replaced the throttle body with TPS and the map sensor. I have spark. Fuel pressure about 35 to 37. engine is rebuilt. I have compression. I checked for broken wires. Replaced the key switch. It turns over but does not fire up. I'm stumped. Do you have any ideas what could be wrong? I did notice there is slack in the throttle cable by the foot pedal. I adjusted the cable. Let me know if you have any ideas. I'm having a hard time believing it's the PCM
It may be possible that your fuel injector wires are backwards and firing on the opposite stroke. When I assembled my rebuilt 2011 ranger 800 xp I had a 50/50 chance of connecting them right. Mine worked on the first start, but I was advised that if it didn't start to swap the injector wires around because that is a sure sign that they were hooked up backwards.
Good luck, I hope this helps!!
@@mmoorehct Thanks, I Found the oil pressure relief valve was stuck, dumping oil back into the block instead of pumping up the lifters. My valves weren't opening. I fixed that and got it to run.
Had a no charge issue burnt 3 yellow in plug-in on pdm under hood cleaned put together started and charged next day went to tryout now won't start atoll will bad pcm do that if so where best place to get new pcm help
06 ranger 700xp only firing on one cylinder. Was running fine kids took it out brought it back on one... New plugs wires coil fuel injectors starter solenoid and battery. Wires are good from the ECU to coil. HELP!! Any suggestions? Would this be a PDM problem? Also headlights and 4wd won't lock in!! Desperate help needed!!
Does this have any power at all? On mine, the dash turns on with key but no turnover and no front or back lights
Great video On my 2006 engine cranks and lights work. PDM seems to be working as power in (large orange) and ground (brown) seem fine. Small orange next to power in 11.5V. But fuel pump not working. Already replaced fuel pump, and all worked well for a few days then it quit again. My sense is there is an open or short. Red/green black line into fuel pump only 1.5V. Recommendations on where to look? Thanks!
It sounds like the PDM is failing in the fuel pump circuit. What I have done is using a relay and in line fuse create a new power supply for the fuel pump. You can control relay by key using the keyed power source on buss bar.
@@montemania198210 Thanks for the timely feedback. Looks like there are two issues. Followed the recommended approach to get voltage to the fuel pump. Even with the voltage, pump would not turn. Thus fuel pump (was replaced a few months ago), was bad. Will replace it. Also saw that battery is 5 years old. Jumped the Polaris batter to make sure plenty of power. 12V delivered to the fuel pump. So will also replace battery. As well. Really appreciate your troubleshooting help.
@@rickstephens479 absolutely btw once you get new battery in make sure it’s charging. Voltage regulator is built into the PDM
So where did you end up ordering that PDM seems like you can't buy them no more they're all in backorder
when i back feed orange wire the machine starts right up, whats next?
When checking the orange wires going to the ecu is your key position off or on?
Key should be in the on position.
I have a 2006 ranger 700 xp, the chassis ground (heavy brown wire in the forward PDM connector) is burning the connector pin. I don't understand why a chassis ground would burn this pin with no sign of overheating the actual ground wire. The ground connection at the chassis (under the driver's seat) is good. Could it be the PDM itself is not properly grounded?
Unfortunately the PDM system is full of mystery and little gremlins. I’ve seen so many different ways of it burning out wires for no rhyme or reason. However I have noticed when this happens on the ground wiring it’s usually do to a poor engine to chassis ground.
@@montemania198210 I found the problem, the stator was shorted. This was causing a feedback to the chassis ground, which manifested as a burned connector pin at the PDM. Thanks for your reply, I hope my info is useful to you.
@@robbiekite4954 great to hear. Keep in mind the PDM has voltage regulator built into. 9 times out of 10 PDM causing stator to go bad. These PDMs are horrible and cause a ton of unnecessary issues. I would recommend replacing PDM, pigtail and the stator. Best of luck to you
I just bought a 2013 Polaris Ranger Crew 800. I was stupid enough to do so with a rebuilt title because of the discounted price, and it worked fine for 2 shirt trips out, and then it died on main st. Got it started after waiting a long while, drove 20 yards and died again. I now have it home in my garage. I can get it to start by pumping the gas but it stutters and then dies even with continued pumping of the gas pedal. I replaced fuel pump, injectors, spark plugs, sensors on the throttle body minus the tps. Im getting a reading on the tps of 3.7 volts in not the normal 5 volts. Im thinking this could be my problem. I have checked all the wires within 2' of the throttle body. Do you think a faulty pdm or ecu could be my issue? Where would you suggest I move on to checking next?
Just saw I dont have a pdm. Any pointers would be greatly appreciated.
A 2013 does not run a PDM so that’s checked off. Pull the plugs and do a compression test. Also check the ohm resistance on tps wire from plug at tps and plug at ecm. If you have resistance on wire you definitely know it’s in the wiring.
This video will help with compression check. Did I buy a turd? Diagnosing Polaris RZR 800 Smoking Engine.

@@montemania198210 Did the compression test, and I have 90 psi on driver side cylinder and 0 on the other side. Passenger side was full of gas. 😞
@@10299059 unfortunately she’s done, time for a rebuild.
