 Let me show you what this bad boy can do. Welcome back to another episode of Titanium Man Garage and today I'm working on that Polaris Sports Spin 400. If you see my previous videos you saw I had issues with the speedometer not lighting up. Also had the fan constantly running with the key off and what I determined it was the ECM along with a couple other issues with the speedometer. For those of you who are not familiar with the ECM it's this little black box right here. Depending what year you might have the silver box or aluminum one. Mine just happens to have the black one. Now what Polaris did years ago was they used a short power ECM and like I said some of them are black some of them might have the aluminum box and what they did was Polaris combined the voltage regulator, rectifier, other circuit breakers and the fan control all of them box. Sounded like a good idea at the time but what ends up happening is like for me for instance the fan stays on constantly so there's a switch or a circuit breaker in there that's staying closed leaving the fan on. Other issues could be the voltage regulator slash rectifier will not charge your battery those go out that's probably a common problem. They do sell aftermarket kits that plug in your voltage regulator that go right here and then they hook to the battery it's actually a pretty simple kept hook up. So I don't have to worry about the voltage regulator because mine actually works. It is actually charging my jump pack so I know the voltage regulator slash rectifier and the ECM is working. So where does that leave us? Well I know I've got the voltage regulator working and if you guys do decide to do the bypass it's actually pretty simple. See the three yellow wires right here in this plug you unplug that you leave it unplugged and with the new kit you just plug it in there with the voltage regulator I believe RM Stator sells them or you could hook up your own voltage regulator if you have a Langer on from behind you can find one for a player so three wires something that would work if you wanted to save money. So my first step is I'm going to bypass the fan and what I did was you can see in here it's like the red and black wire that goes up to the ignition switch comes down here and orange is hot brown is ground I hooked that right into the key switch so now fan stays on constantly I don't know if you can hear it running I did have to replace the fan because I'm assuming because of what happened the key stayed on the fan it kept running the last owner probably didn't know it burned out the fan this is what the fan looked like I mean look at it if you guys can see that in the camera it is really wobbly loose I literally had to push it to get it to start working so yeah that fan was shot so this fan probably has more hours on it than the whole ATV itself because I was running non-stop for a couple days got a used fan from off at eBay I could tell you the name of the company but I'm not going to get paid for it so hook that in directly now is this a good idea to do you might be asking yourself it's a fan I'll say running all the ATV is running only on the key switch as soon as you turn the key off the fan will shut off if you have an old player us and you know you want to save some money and you kind of don't care this is a way to bypass the ECM if you want to do it right spend the 260 to 300 bucks on a ECM go ahead put it in I'm just showing you guys a little shortcut on what you can do to save some money if you want to keep your wheel running if I was gonna turn around saw this I'd do it right but this one I'm probably gonna hang on to now you may be asking yourself yeah titanium and that sounds great but my hot light is still flashing on the speedometer I bypassed the fan but that's still flashing well let me show you a little shortcut to that to do is to grab the where your harness down from your speedo and then I'll disconnect it you look for the blue wire with the white straight right so you take the blue and white wire off the harness going up to the speedometer watch what happens when I cut it what do you guys see guess what no more hot flashing light boom problem solved so I just learned a lot of this information within the past couple days if you see my older video I actually took a 2005 ATP and how I bypassed the ECM last time was I took the whole wiring harness off grabbed the wiring harness from I believe it was the 2004 that didn't have the ECM it just had the CDI box and the voltage regulator and I installed that instead just learned a lot of this information from one a video on RM stator and two one of my subscribers long time subscriber small garage hustle he actually gave me a little bit of info to on how to bypass this thing and I just put two and two together and figured out myself now down the road am I gonna need a voltage regulator I probably will I'll probably do the bypass and I think that's like a hundred sixty bucks versus you know the 260 to 300 so for now I'm just gonna run it like this but you might be asking yourself all right well why did this happen well my first indication was when the speedometer didn't work I first checked for power had a friend of mine do a continuity test because he's better at electric than I am and he realized that it wasn't a power issue it was a ground issue so I added another ground wire as you can see right here tied that into the ground wire to us going to the speedo and ground it to the frame now the same thing with the ECM majority of the time something electronic goes out is because you have bad grounds so your speedo goes out before you ride it too long and mess the whole thing up check that ground wire otherwise if you keep driving it that way you're gonna wreck your speedo guess what you're spending 260 bucks on a replacement same with the ECM I found out the grounds are bad going up to the speedometer I also double-check the grounds going to the ECM I actually think that's why the ECM fried I also found if you seen my previous video one of the wires were actually pinched going to the ECM I'd fixed that back up and I reinstalled the ECM yeah it's unfortunate the way they grounded everything on these because I don't know it was me I would have added a shit ton more of grounds even on your 4x4 a lot of times if your 4x4 switches are working it's either power going to your switch that's corroded or 90% of the time it's your ground wire going to the 4x4 a lot of times I'll just put a jumper wire on the ground on the wire is going to the 4x4 and that usually cures my problem so I'm gonna get this thing button back up said this is a it's a cheap bypass on your own unit if you wanted to save some money it's the best way to do it if you don't mind your fan running all the time you know yeah could you burn out your fan yeah but 35 bucks for a fan a used one yeah just buy another one replace it or you can do what a lot of guys do and they put a toggle switch on it which I think is a bad idea because you'll be right in your four-wheeler and you'll forget to turn the switch on and blow head guess here you guys go this is info I learned within the past week thanks from some help from a subscriber and a couple YouTube videos this thing should be ready to fly in about an hour all right here you guys go the light player sportsman 400 ECM bypass runs the drives good it's keeping cool thumbs up if you like the video and like always till next time
