Please help. Iv got an 1990 lt80 that will not charge the battery. I can’t seem to find the answer to the problem. Is it the rectifier or the Cdi box or something different all together. I can’t seem to find any rectifiers for it so I’m stumped and I don’t have a manual to read up and find the answer.

Did you ever find an answer to this? To check a rectifier you can check the diodes with a multimeter. Should have .3-.8vdc one way and none the other way. Also, check the stator legs for continuity to eachother and no continuity to ground.

As everyone else has said check those things, also try and locate a service manual. They are miracle workers sometimes. I would check rectifier sign the known good values. They are easy to pull out and check them or leave them in. Also check the battery itself.. I’ve had my fair share of luck with factory dead cells.

      Suzuki LT80 no start, no nothing
      By T_odie
      Hey guys, hope you can help me out here. I was gifted an early 90s LT80 and it had sat outside for a couple years. Upon inspection I noticed the wiring harness was all chewed up and had couple splices. I tried to get it to work and was getting nothing when I pressed the start button so instead of messing around with it more. I just ordered a new wiring harness along with a starter relay.
       
      I have everything hooked up but the clip on the new harness for the CDI/coil is 4 prong when the cdi/coil is 2 prong. Is there anyway I can splice this into the two prong adapter or do I need to get a new cdi and coil.
       
      Also is there a way to test the start stop switch on this as I’m narrowing down why I am getting nothing when I try to start it. Relay doesn’t even click. I have sliced the brake switch and the reset button wires together and am getting nothing. Shouldn’t it still be turning over without spark if the coil isn’t connected?
       
      Please help and thank you

      1987 Suzuki LT80 Fuel line routing
      By nix377
      Friend of mine picked up an LT80 that needs some work. The manufacture date is 11/1986
      The fuel and vacuum lines for the carb were all disconnected. I picked up a new card and was hoping someone on here has a photo or knows how the lines are hooked up
      Thanks in advance

      New project - LT80
      By shar
      Picked up an LT80 (unknown year) for $200 recently for my girls. Not running at the moment, but does turn over. I’m thinking the carb needs to be rebuilt or replaced, as it appears to be leaking 2 stroke oil. Anyway, I’m excited to have something to wrench on in my (limited) spare time

      Hey y’all!! Newbie from Louisiana hoping to learn a little something 🤷🏼‍♀️
      By QuadConfussion
      Hey everyone! Just introducing myself and hoping I can get some insight on where to start. I have an older quad, my guess is about an 07. I know it’s a 700 but I’m having some stalling issues with it after it runs for about ten minutes it will die out. It will start right back up and run but after a minute or two it will die again. Any suggestions on where to start checking things?

      First Problem Ever, 2014 KingQuad
      By PGregory
      1700 miles on the machine, all trail riding.   Second ride of the day and I get an overhead light, shut it down, let fan run, fan shuts off, light still on, ride back to camp, clean radiator, let machine cool for a couple hours.  Start up, head over to the campgrounds, ride for 5 minutes or less, overheat light comes back on and the machine blows the ignition fuse.  Tow it back, replace fuse, turn on key, fuse blows immediately.  I've ran all the wires, no mouse chews or rubbing, etc.     Does the KingQuad have a thermal protection system that would explain this?

      I am looking for pictures of your carburetors, specifically looking for what type and where the hoses go on the red circles.
