Also plugged in new regulator while starter is isolated and still popped fuse 🙄Red wire is showing continuity while it is attached to starter but dissconected from solenoid but the wire looks good ,there is no kill switch that's the only part that varies on diagram just a switch on front brake to let starter to operate ,starter turns over fine

The first thing to go wrong was the electronic 2x4 to 4x4 sensor which ended up buzzing as soon as I put ignition it is now  unplugged could this have been a short in here and freed the cdi ?

Anything is possible so yes the 2x4/4x4 could be causing a short. 

Can you see if there is a purple wire coming off the cdi and trace that back to maybe the brake switch your mentioning and disconnect it. Test it this way and see what goes on.  

The 4x4 selector if possible unplug it and see what happens.  I will go back and look at the diagram and see what I can find.

That’s some good work.  Just keep one thing in mind and this will throw you off a little bit. There are resistors inside some of the components with the cdi and other items like that work like a light bulb.

For instance a light bulb is connected to a ground and a positive to make it work correct ? So you should get a resistance reading on the red and black wire going to that bulb because the element inside the bulb bridges the red and black wire but at a very low resistance rate. That’s why a lot of the repair manuals show how much of a resistance reading  you should get on certain parts. Like you pick up coil and or the stator etc.  So don’t automatically think it’s a short when you get a continuity reading.

So looking at your diagram that you posted. That pick up coil is bridged so automatically you will get a continuity reading on that.  Along with the ignition coil etc.  unfortunately you really can’t test a cdi. But you can test the other two items, pick up and ignition coil.  That information should be posted in the manual as far as the acceptable ohms reading.

Ok great so keep going trough everything to rule out any shorts including a good inspection of that 4x4 selector switch and see what you come up with.  Hopefully you put the oem regulator in and the cdi and she fires right up.  Leave that 4x4 selector unplugged before you try to fire it up and see what happens.

Great job brother.

      I have bought a 1996 suzuki king quad 300 and I have noticed that it smokes but I have put oil in it and plenty of gas had to fix shifter bc the nuts and bolts came out somewhere. I have had to replace the wire for the starter but now when I try to start it it wont idle at all and when it does run it smokes really bad like a whitish blue I guess, and it likes to stall a lot. So anybody can help me out please and thank you

      hi
      Where installing a winch to KINGQUAD ltf300?? someone have any pic?
    • By Dra O
      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
