I traded my dirt bike for a 2000 arctic cat 500 semi automatic. when i went to go pick it up the guy said it didn't get spark, so i thought it was going to be something simple like a coil. well it wasn't. first thing i did was take all the plastics off to get easy asses to every thing. so i bought a brand new battery for it seeing if it got power, it didn't. the dash wouldn't light up neither would the lights, so then i tried to see if the starter worked it didn't so i jumped the solenoid and the starter started turning over the motor. so i bought a new starter solenoid, when i installed it the electric start still wouldn't work , so i bought a new kill switch and starter switch that goes on the handle bars, when i installed it, the electric start still wouldn't work. so then i went to see if i could get spark by pull starting it, i didn't get any spark, so i bought a new spark plug, and guess what, still no spark, so then i bought a new coil for it to see if that would fix it. so i installed the new coil and guess what no spark still and still no power to the dash. so to sum it up i'm not getting any power any where to the four wheeler. so i cleaned all the leads and plugs and still nothing. so then yesterday i took the wiring apart to see if their was any frayed wires, and no their wasn't. does any one have any ideas what this could be i'm up for anything. also if any one knows how to bypass all the wiring just to get it to start i open to that to, or if someone knows where  i can get a wiring diagram.

Couldn't find a  free  service  manual  or  wiring  diagram  .     If  you  have  no  power  to the  lights  or  anything  then   the  problem  is in  a mater  relay  if there  is one ,  or in the  ignition switch .    Not turning  over  on the  starter  could be    a safety  switch  or  the    transmission is  not in  neutral .  Start  at the  battery   positive  and  ground  and  trace the  wires  out .  Check the  neutral  switch  and     safety  kill  switch.  Check    any  and  all  relays . .    Once  you  find out  why  the  starter  doesn't    work  with the  start  button   you  may  also  find why there  is no  spark.  No  spark  could be  the  stator,  pickup  coil   CDI  box or coil.  Most of those  you  have already  replaced .  Take it  step  by  step  from the  battery  out  check  connections  for  corrosion  and wires for  breaks .   A wiring diagram  helps a  lot  ,  but methodical  elimination  will  do  the  job .   You  could  try  looking  at the  wiring diagrams  of  other   arctic  cat  models    for  qa  clue  of  how  they  are wired .  Most likely  they   are all  wired  very  similarly  if not identically .

take an electrical detector and check along the wiring harness to see what has power.

It is your voltage regulator. Just had to replace the one on my Arctic Cat 250 2003 again. When the voltage regulator goes it fries the battery and nothing will work. So if you got a new battery without checking the voltage regulator and tried to pull start it you probably fried the new battery too.

By his description he is not getting power to anything even with a new battery, so I would start with the ignition circuit, could be something like the key switch is bad. He may not have checked basics like fuses.

      Looked at this one-owner 1998  454 today.  Pics below.  Do you see TONS of cash being tossed into this thing?  I like the low miles but I don't like the electrical "arrangement."
      1360 miles - one owner that used it for hunting - owner said it has been outside, as is, for 5-6 years (he originally told me 10 years).
      -a marine battery charges EVERYTHING (I didn't think this was possible) - he did this primarily for the wench  - a charged 12v battery didn't turn anything on the instrument panel - a charged marine battery would help but I didn't have one in my back pocket
      -no oil detected after taking off cap and I put my finger in DEEP.  no gas in tank.  brake fluid reservoir not dried up but has dark/old fluid
      -tires w/ good tread but cracking walls - some rims rusted but appear to be straight           -air box dry but filter old/useless       -original carb - didn't take out to inspect
      -foot shifter felt good/cycled through the gears      -pull start worked but I failed to check for spark
      -and then there's the WIRES... and WIRES... and WIRES.   Basically neuroanatomy 101.  More like Arctic Cat Nightmare 101.  New wiring harness on ebay runs around $70 - but this guarantees nothing.
      But the plastics are good
      Thoughts and opinions welcomed.  "Run away" -- "You're an idiot if you pay more than $XX for that piece" -- "Don't even THINK about it"
      Pictures below - may involve a second/third page

      Hello bought my 2000 polaris sportsman 500 last week bike seems to work pretty good untill yesterday, when in reverse the bike seems to start bogging out? How come?

      Have any of you fine folks used coil spring spacers to lift an ATV? Ole 93 Kodiak could use a smidge more lift and they are cheap enough. Might ride rough but that's ok cuz the shocks are toast anyway. 
      Thoughts?

      Hey everyone, I've been scratching my head over this for most of the day.  I bought a couple of Bayou 220's, got them running (they've both been sitting), and started tweaking and fixing small things.  One of them is mostly done, the other had an aftermarket carb on it and I've been trying to sort that out.
       
      Anyway, while adjusting the carb it died a few times, I restarted and moved on until it died and wouldn't restart.  I figured maybe I'd flooded it or something - after further attempts I realized I had no spark.  Since I have two identical machines I have many parts at my disposal.  I've swapped the CDI, spark plug and coil with no luck.  I have good resistance readings from the stator and pick up (135 and 110 respectively),  I don't have a peak voltage meter but I measure around 53VAC on the stator when cranking.  I have a 4 wire stator, not an alternator like the newer ones.  Grounds look good, I've checked the kill switch by verifying that it and the ignition switch grounds the black/yellow wire to the CDI.  I can turn the engine slowly and see the pickup short the meter as well, seems normal right?  So far everything I've checked looks the same on both machines.  I've got the service manual and wiring diagrams.  Do these readings make any sense?  I'm obviously missing something but I'm stumped.  thanks!

      Hi guys im new here and ive been doing alot of research on my polaris predator i was wondering if anyone on here has wired a different cdi up on there quad? Not a direct replacement that would simply just plug in. I know my white an w/red wires go to my pulsar my green an blue go to my reverse coil but im unsure which is + and which is ground also brown/w is a ground correct? What about purple? Black goes to my kill switch and red is my 12v supply........then ive got yelloww/red , yellow / yellow that goes to my rectifier..........any input on this subject is greatly appreciated thank you all

      I have recently rebuilt my Yamaha warrior 350 engine and when I got it all back together with no “spare parts” i went to start it and realized it’s in reverse. I went to put it in drive and the shifter won’t budge, I took the linkage off and tried to use vise grips but it won’t budge at all. Any help would be greatly appreciated. I’m hoping it’s not something internal!

      Hi, I’m a 16 year old that is wanting to get more into vehicle and mechanic repair. My dad has an old ‘96 Timberwolf that he doesn’t remember running since I was born. I want to get it running again as a memory for him and to help us be able to hunt together, and of course so I can learn how engines work more than the little information I know now. I’ve pulled the carburetor and gas tank off of it, and the carburetor is getting cleaned by a friend. I can post photos of the condition it’s in later, I’m just curious where I should start in my journey to get it running again. The power switch is broken off of the handlebar, so I am looking into fixing it, along with the pull cord. I’m afraid the engine is seized up, and I’m curious to hear any input anyone has. Thank you all.
