I have a 2006 Sportsman 500 efi the ECM modular is burnout,I just watch a video of your changing the wire harness, do you think I can that on my wheeler
Now the wrench flashes all the time but whats really worse is the dan coming on with the key. Its rare for the 500 fan to even kick on till it goes hot. Your better off adding a switch and run the fan on hot days while hauling or towing something.
sounds like if the ecm is giving faulty Hot signal, trace those wires and verify thru a wiring diagram that you can cut and bypass the ecm , splice those wires together, free fix , but you would have to monitor your coolant system manually or add in a cooant temp meter so as not to overheat. .... ecm may tend to ground out in that area if its happpened many times is my guess?
I know this is an older post but just out of curiosity maybe I can get some information on a situation I have a 2008 Polaris Sportsman 500. Is there a way to delete the ECM on that machine. I think mine is bad I have no spark and my fuel pump is not kicking on okay then replaced all my fuses and relays. Thanks
A little off the subject... I have a 2012 Sportsman HO 500. Back a few months ago I noticed around 5000 rpm it would bog down and almost die.. It idled and run fine otherwise. Since I hadn't rode the thing very much, I believed it was trash in the carb. I cleaned the carb and replaced the jets.. No improvement. So, I purchased and installed a new carb.. Problem didn't improve. I changed the plug.. No help. I replaced the pulse pump and all the fuel lines.. No help. Removed and cleaned the tank.. No help. I knew the air filter was new, so I hadn't even given it a thought, that it might be the problem. But, one evening while listening to the engine idle, and revving it a little.. I thought I'd remove the filter cover and see how it run.. and it actually improved a little.. So, I removed the filter, and it improved a little more. And that's when I found the culprit. All that money spent on parts, time of changing them out.. and the irritation of worrying about this bike.. came down to the hard plastic sleeve inside the rubber breather tube, that prevents the rubber from crushing when you tighten the air filter onto the rubber intake hose. When I replaced the air filter, I had invariantly caused that little hard piece of tubing to be turned sideways inside the rubber breather hose.. which allowed enough air for the bike to idle and run half throttle, then fall on it's face around 5K rpm or so. Moral of the story.. Check everything, even if you think it's correct.
Great video! I just bought an 05 scrambler 500 not running, once I got it going it has some mysterious electrical issues. like with key off the dash lights would light up randomly neutral then the hot light or reverse or they all would come on at once had my local dealer run my VIN and sure enough it still had a open recall on the ECM. So that’s where it’s sitting now. Keep up the videos they are great! I like wrenching on older Polaris’s as a hobby if I get stuck on something I usually find a video where you’ve explained it and it’s pretty helpful
What about radiator fan running all the time , isn't that going to take up all amperage from stater coils , I believe there something like 1.5 to 2 amp output , what about battery charging ?
i have a 2001 polaris sportsman 500 ho it cranks not start. but it only starts with a jumper I'm not sure what the issue is. Ive replaced the starter, fuel pump, and cdi box. if anyone knows what the issue is please tell me.
By hot wiring the fan, do you intend for the fan to always run? I'm not sure my fan has ever run on my 1999 Sportsman 500, can I connect it to a battery to see if it works?
It would be impossible for me to find 2004 atp parts. My grandmother has an 05 with the bad ecm. Polaris doesn't offer them for sale now. I'm trying to look into using all the electrical off another Polaris 500 quad.
I have the same atp and my dad replace the ecm from another atv and it work 4 days and ecm just die. You must buy original ecm to have a good and working atp.
I have an 04 scrambler 500 with a cdi box, regulator rectifier, and ECM. I am so confused. I concluded to a bad stator, (not charging) and tested it with a multimeter. I can't find a stator with the correct wiring so far. I need this thing running by next weekend, any ideas? My brain hurts. I also have a parts sportsman 500 that looks to have the same system as my 00 scrambler 500 that I know works, can I just swap that harness in? Or easier yet, can I cut out the old stator and splice in that one?
Will this work with all Other ECM I have a ELECTRIC CONTROL MODULE (ECM), Polaris item: 4011090 that has been on BO for over a year not activating my fuel pump
Probably a stupid question, but how’d you Hotwire the fan? My fan won’t kick on once engine starts getting hot. “Hot” flashes on screen once engine gets up to temp. Not sure how to fix this issue. Thank you.
@@TitaniummanGarage I Hotwired the fan with your method for ‘05’s and up and the fan did not come on. I ran 12v direct to fan and it does run so I know fan is good. Any other ideas? Thank you!
If it's a 2005 you can unplug it and it will always run. The plug is located by your fuel filter on the side of engine. If you unplug the two wires it should turn on.
An alternative solution to this is to eliminate the ecm box entirely with a few basic changes to the wiring. I successfully deleted mine from a 2004.5 sportsman by connecting the circuits together and adding a Honda atv style voltage regulator. Battery is charging fine. Will need to either run the fan constantly or find a fan switch solution.
Mines charging at 18 volts at idle. The quad has only 1000 miles and 260 hours. It doesn’t have the black elm. Should I just by a new ecm? Mines a 2005 Sportsman.
@@TitaniummanGarage they have the Voltage Regulator built into the PCM. I’m gonna ohm out the stator tomorrow. The dealer told me today to check it first. I actually have a great dealer by me.
Got ya, yeah I’m kind of up shits creek because I can’t seem to find an ECM anywhere.I’m not having issues with the fan continuously running or anything. The only problem I have is if I run the machine for a little bit and then turn it off it doesn’t start back up for a couple minutes I guess it has to cool down or something.
I have heard of that happening to guys. I think your on the right track. Check all your ground wires. By the speedo/light switch. There is a ground by the rear left tire and up in front. Try to add an extra ground wire. I had to do that to this one. Some wires were turning green so I didn't trust the ground wire.
Martin, you shouldn't have any issues with using a 04-06 sportsman 400/500 ECM (Part#2203348). You are correct though about not having turf mode. I was considering the rewire that Titaniumman Garage performed but after reviewing wiring schematics of the 04/05 ATP and the 05 Sportsman I decided against. One, I couldn't find all the parts I needed at a reasonable price if at all. Two, I found that both 05's were virtually identical less the turf mode and tail light configurations. It was a good call on Titaniumman's part just wasn't going to work for me. I just got mine running this week and everything seems to be working fine. I did take some advice from Titaniumman Garage about the 04 wiring, I did purchase an 04 ATP Differential Solenoid Switch and rewired it to match my 05 so I'm still able to use turf mode. I like to keep my equipment in as close to the original working order as possible and this seemed to do just that. Hope this helps, good luck and thanks Titaniumman Garage.

I showed the picture on ebay for video purposes. I found a guy that was parting out a 04 ATP. Got the harness for 50.00 and the flywheel and stator for 80. plus additional parts. I had done this a while ago. I don't have the parts and numbers off hand. Check Partzilla.com for cross reference numbers. I did the work online to see what would fit. You can too. Or find a guy parting out a 04.

My 2007 Sportsman 450 is $500.00. Some companies like Module Masters rebuild them, but unfortunately, not my model. Nice video!
I have an 04 ATP, has been an amazing atv. Love the back box and the turf mode

True. but the down side is people forget to turn the fan on. I bought 2 with fan switches and blown motors.
My 2005 500 atp ECM is sizzling and smoking. Where you located in WI. I'm in Southern WI.
Where did you find the different solenoid stick on the front

Good Catch. I have so many people asking that same question. It could be anything. Most of the time its something pinched not letting air to flow in.
Where do you order the ecm from and how to know whitch one will work

My polaris scrambler is shutting of randomly and when i fully gas it it doesnt go but only at half throttle
Do you have a complete parts list for doing this
Seems every wheeler I get in to work on has had radiator temp sensor bypass an fan running full time !
What about radiator fan running all the time , isn't that going to take up all amperage from stater coils , I believe there something like 1.5 to 2 amp output , what about battery charging ?
There is a chance the fan could burn out after some time. Some guys add a switch to it.

@@TitaniummanGarage they have the Voltage Regulator built into the PCM. I’m gonna ohm out the stator tomorrow. The dealer told me today to check it first. I actually have a great dealer by me.
Oh yeah. I was thinking of the 04 conversation I did.
The ATP had that "Turf Mode" to prevent damaging grass on golf courses etc. That must be the difference with the ECM
No..The 2004 had the turf mode as well. it plugged right into it.
Do you know what flywheel and stator you had to use apparently they had 2 they used on the 2004 . The flywheel should say ff97 or ff95
I'll have to check. I believe it was a ff95
Doing the swap and ran into the issue of finding a stock rectifier . Are the wire colors the same on the harness plug to the rectifier?
Do you have a wiring diagram for a 2004-5 Polaris 500 ATP
No..I don't. It was all plug and play. I just matched everything up when I replaced the harness.
It's the back two pages of the service manual. I can provide if needed.
My ecm plug melted down. Literally melted. 05 500ho, looking into a new ECM, or this project.
I put new CDI in, turned on key & melted the power wire to the ECM. Now it won't even do anything when I turn the key on.
Hey, if I use the ecm from a 2005 sportsman 500 can I just plug it right in and will everything work correctly besides turf mode ?
That I'm unsure of. The part number is different. Not sure what else is?
Got ya, yeah I’m kind of up shits creek because I can’t seem to find an ECM anywhere.I’m not having issues with the fan continuously running or anything.
