tether kill switch on a 4 stroke 2003 Polaris Predator

well when i bought my quad my buddy had broke the ignition when it was rolled

yea i know sucks right

but it runs and drives fine the like cluster w. the key and temp and neutral light its just smashed so i took it off

but i wanted to put a tether kill switch in for a key

right now i just have the 2 red wires crossed and its always on if i hit the kill switch it shuts it off so the battery wont die

anyways i took the tether kill switch off my blaster (2 stroke) and went to put it on my 2003 predator (4 stroke) and they work the opposite =(

when the tether is pulled on the 2 stroke it makes a connection (im guessing short to ground) which kills the ignition but on the predator it needs to make an open cause these 2 wires need to have power flowing through them to have the ignition on

so i ask has anyone installed a tether kill switch on there 4 stroke? and any tips

or does anyone have acces to a wiring diagram for a predator ignition

sry for such a long post:confused:

Well, I think the best thing to do would be to buy an open circuit switch. If you really want to use the kill tether from your blaster you could wire in a Bosch relay that will send power to through one circiut when no voltage is applied and to another when the relay is coil is activated. You can wire the kill tether into either the 12v+ feed, or the ground feed, which will go to termilal 85 or 86, it makes no difference which terminal is positive or negative. Wire the ignition feed into terminal 30 and out of terminal 87a. When the tether is connected, the relay circiut will remain closed keeping power flowing from terminal 30 to terminal 87a and the ignition will stay on. When the tether is pulled, it will close the circuit and energize the relay coil, switching the current flow to terminal 87, which is not used and therefore opening the ingnition circuit, killing the engine. If you need further clarification, google Bosch relay, or SPDT relay.

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      My king quad 700 runs rough when cold then won't start some times but not often when it's hot. And occasionally smoke's a lot when it's cold I'm guessing that's rings but I'm worried unless it's causing the other problems
       
       
       
      All help is appreciated thanks

      My friends KQ 300 starts fine and runs, as soon as you put it in gear and try to accelerate its bucks and farts like crazy, not moving... I cleaned carb and it worked good for 1 day... now back to same problem.... could it be such as a bent valve????

      Hi everyone. 
      Let me explain the thread title. 
      My husband and I are very active in the nudist community, and we have stayed at many and most of the mainstream nudist and clothing optional campgrounds in the USA. We are now approaching our retirement and would like to start a podcast to share those off the road / backwoods / little known camping areas where nudity is allowed. We have purchased a 5th wheel camping trailer with a rear garage for the ATV and now need some good reports on the one to buy. 
      We are most interested in a side by side unit but would love to get your thoughts. 
      Feel free to stop by and say Hi and ask anything you would like to better understand what we are looking for in an offroad unit. 
      Thanks for reading and hope to hear from you.

      Bucking started about a month ago and works ok after 1/2 hour warmup.  Today while working on it i discovered that if i put the ignition switch in LIGHT position it runs fine right from the start.
      I'm stumped!  Any idea why this could be?
