1992 timberwolf 250 2wd will only start if the neutral light is OFF


VikingTrad3r

Recommended Posts

picked up my third timberwolf 250 for my daughters.  these are great light weight little quads.

 

have a strange one for you.  the quad will NOT start in neutral.  it will start in first. 

if i lift up on the gear selector just enough to hear the little click (its not loud, sounds like a contact clicking, perhaps the neutral safety switch?) the light will go out, but it won't yet be in first either.  that is how i have shown my daughter to start it and she can.

 

id like to carry out whatever repair is needed.  i have the pdf of the shop manual but it doesn't really have a flow through diagram.

 

any help appreciated!  thank you.

i need to add something.  it feels like i can switch into another gear BELOW neutral.  

so if i switch to neutral, i can keep pushing the gear selector, and it has another click below the neutral.  the light stays on, and when i pull up into first it kind of feels like it has two positions it moves through to arrive at first.

Since I am not familiar with the Timberwolf , I  can  only guess at a possibility from your description. My best guess is the neutral  switch or the mechanism that activates it is either loose or broken so that it is out of position. It may be a simple adjustment and tightening required.  Open  it up and have a look. Starting in gear  is unsafe, especially for a  young rider.

im back with more info.

first, the reason it felt like i could shift below neutral is because the shifter leaver was loose. thats fixed. 

 

but the main issue remains:  here is an update, 

 

1. the reverse indicator switch is broken down on the left side of trans. i dont think that affects the starting circut though. ive ordered the switch. 

 

2. it WILL START if its in neutral, but only i have the neutral switch unplugged. IE, the neutal light is OFF. 

so something about the neutral light being ON when im in neutral, stops the quad from starting. 

its like there something reversed somewhere. 

 

the quad is ONLY. supposed to start when the neutral  light is on but instead it will only start when its off.

switches are functioning properly. 

ive discovered something else. the reverse indicator light bulb is mia. so was the reverse switch. installed rev switch. 

had s bulb laying around, blew rev i dicator bulb immediately.  bulb mau be too wussy though  

 

anybody know where i get a replacement bulb?  this is for the little red bulb  the actual bulb

i tested the reverse position indicator light socket/receptacle and its showing 12.4 volts. the little bulbs i put in were rated for 2.4 volts. so i think that explains why they glowed very bright for a second then burnt out. 

 

so does anyone know where i can get a real reverse indicator light?  it would be the same as the neutral light id imagine

Just replying here again.  The reverse light is all good fixed.

 

The main issue of only starting in gear is not solved.  im not super skilled at reading wiring diragrams nor troubleshooting wiring.  i thought i had it narrowed down to a relay.  ordered the relay but still not fixed.  quad will still ONLY start if the neutral light is off.  It is starting in gear, but wont start in neutral.

is it possible that a wire is reversed somewhere?  seeing as it is doing the opposite of what is supposed to be doing.

If I read the schematic right the neutral  light (19) and the path to  ground for the  starter button relay (11) should only be on when the neutral safety switch ( 20)   is closed.

That would indicate to  me the problem  is  in the mounting of the neutral  safety switch.  For  some reason the switch is open  when in  neutral   and closed when  in  gear.  There is either  linkage  not set right or  is it possible to  mount the switch  turned 180 degrees?

Disconnect the wires from the neutral switch and check  for continuity  in the switch ..  In  gear  it should be open  (  no reading   on the meter) and some  value  close to  0 when  in  neutral.

      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

      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?

      Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.

      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.
