2014 Sportsman 400 HO - No Lights

Recommended Posts

2014 Polaris Sportsman 400 HO

We had an issue with the lights working on occasion.  Then they just stopped working completely (front and rear). We looked at the EFI fuse and it was melted, but not blown.  We replaced the fuse, but now the ignition will not turn on UNLESS we pull the fuse out...and BTW, the lights still didn't work with the new fuse. Any help would be appreciated. Thanks!

The fact that the fuse melted tells me there's a short somewhere. Do you have a manual with a wiring schematic? Where the fuse melted, start tracing that wiring to see what could have caused it.

I thought the same thing.  However, I found that when I pull the relay out. The lights work fine. Is it  possible it's just a bad relay?

Try this.  Leave the key on and pull the relay. See if the relay clicks when you pull it.  If so then the relay is working.  Or just touch the relay and see if it clicks when you turn the key on.   

What I would do next is trace the wire that feeds the lights and disconnect it. See if that changes anything. Does that bike have a digital screen on it ? Any codes ?

Do what @Frank Angerano mentions, see if the relay is working.

      Friday evening went riding, rode for a good hour or so everything was fine. I went to take a short ride to the restroom (less than 100 yds away) and all of the sudden everything flickered and then just died out. Accompanying the problem I noticed the killswitch completely locked up. Once daylight hit took the killswitch apart to find it had shorted out and melted the plastic inside. Has anyone else had anything similar to this and if so what did you do to fix the situation? I have a new killswitch on the way to replace the obvious problem but was wondering could there be a bigger issue at hand. We tested with a voltage meter to make sure everything was still getting power from the battery and as far as we could tell it was.
      Any advice/info would be GREATLY appreciated.
      Thanks.

      Hey there, i have recently put a new drive belt on my 11 Polaris Sportsman 500 H.O.    It has 44 miles since putting the new belt on and should be nearly broken in as i hear it takes 50 miles to do so?  Anyhow it has had a little trouble with slipping since i put the new one on a few months ago. Now whenver i go down a hill the belt seems to be getting caught in one clutch if not both and then it has to run a high rpm just to go a low speed.  Today it did that again going down hill, i stopped, put it in neutral and when going back up the hill i had to turn it off, put it in neutral, let it roll back down the hill a little, then restart it, low range and it was slipping but thankfully i was able to make it up the hill. 
       
       So what might the problem be? Is this a need for another new belt? New clutches and belt? Or just get something else? BTW the brand new belt i put on it, is a factory one, an exact replacement for the original.

      Hi all, I was gifted this Bayou but she's been sitting quite some time. It won't crank using the factory start button but when I jumper the starter solenoid it cranks but there is no spark. The key has power coming in on the white wire and when turned on supplies power to the brown wire coming out.

      I guess I should start with testing the pickup? I heard I may be able to jumper the wires coming from the pickup with an LED bulb and it will flash? I noticed in the manual that it should have around 110 ohms resistance so I'll check that as well. One thing I noticed was that the starter circuit relay has power on one of the black wires with the key on- this doesn't seem normal as I'm assuming the black wires are grounds? I think one of them comes from the start switch, travels through the starter circuit relay and then grounds the starter relay?
      Mine is a 1991 so it has the 7 wire CDI (ignitor) and a 2 yellow wire alternator ( as opposed to the later 3 wire type ) with another 2 wires for the source coils (black & red wires ). The pickup wires are blue and black I do believe. Any help appreciated and yes I will test the pickup ASAP.

      I'm trying to understand how the system works and I don't understand what the yellow / red wire from the kill switch does- I assume it gets grounded when the kill switch is "on" and therefore grounds the CDI so it can't activate the ignition coil? I noticed in the diagram that that yellow / red wire looks like it may be grounded by the ignition key switch when in the "off" position?
      I also don't have 12v power at any of the wires going into the CDI- doesn't the CDI need to be powered? I also read on this forum that someone used a GM HEI module in place of the factory CDI just to test it for spark- does anyone have any info on that?

      I hope I'm not missing something simple!
      Here is a link to the diagram for my bike (which was posted by another user): https://www.quadcrazy.com/atvforum/topic/13742-1988-bayou-220-lost-spark/?tab=comments#comment-101193

      Any help appreciated!
