any 4 wheeler experts
My dad has a 1985 honda fourtrax that wont start, it turns over but does not get fire
we replaced the ignition coil and the voltage reg. and still not getting fire to the spark plug.
anyone have any ideals

You need a good battery. Mine won't start even with the kick starter if the battery gets low. 0 -

I wish that was it, but we put a new one on thats fully charged.0 -
Yea, put a bttery charger on it then see if you get spark. 0 -
Crappy problem to chase down. Check all the switches to make sure something isn't grounded. Check connectors. Some manufacturers put an oil level switch in, but I don't think honda has one. CDI?[;)] 0 -
if it has a cut off switch,(on the bars) bin it & side track it. its a small problem you got, but sounds like it gettin outa hand on the $$$$.
check the earth/ground cables,for good contact, too. [;)]0 -
If you have a voltmeter you can trace the wiring harness to find exactly where the problem is. I would guess that its the Electronic ignition module. 0 -
I'm not trying to be a wise guy here!!
Be sure ALL of the switches are in the "ON" position!!
Be SURE it is in neutral!
Then start looking for shorts in and around all of the on/off switches and safety switches.
Wait for Cutiegirlracing, she will know whats wrong for sure.
I have a 1988 Honda 250 that will start with the kick starter and a dead battery.
Good luck,

and were would that be [:D]
Mond its not really cost us to much I have a friend that has the same 4 wheeler and iv been pulling things off it tring on dads [}:)]
but the voltage reg. was bad so i got one and it worked fine on my friends when i checked it but still no fire on dads with it.

Trouble shooting is an art form. The basics is that you start from the power source and work downstream from there. Where you find the power stoppage is where the problem is. If you can jump a switch and there is a spark, then you have found the problem.
Most mechanics are just part changers. They will change a bunch of different parts and when they accidentally hit the right part they charge you for all the other good parts they changed to find the right part.0 -
CHECK YOUR GROUND 0 -
Sounds like something simple to me, but I am no expert, just a firm believer in Murphy's Law.[:D]
Maybe your run/off switch has gone bad, maybe water got in it, and it is stuck in the off position.
I'd try to take in loose/apart and see if you can clean it up.
You may be able to bypass it and put another type of switch on it.

Start with the simple stuff first.
Check all of the fuses.
If you are using an NGK Plug. Try another plug. I stopped using NGK plugs when I got tired of buying 5 to find one good one.0 -
New plug, new wire, and a can of quick-start.
I let mine sit up for a couple of months, went to start it, and it just wouldn't fire. Turned over fine, just no spark at all. New plug and wire set me straight. Runs like a champ.0 -
Change the damn plug ya cheap bassturd. Don 0 -
Check the kill switch below your headlite
dimmer switch the kill switch should be
centered.
Do not ask how I know this.0 -

we checked the coil and spark plug wire by putting it on the other one and it had a good spark and started up fine.
I think this is going to be a matter of chasing down a short
on a side note I checked it with the voltage reg. that I works and I got a very fant spark the kind you cant see but I held the wire it felt it but it was so weak i missed fellingit a few times.
thanks for all the input I plan on doing some more work on it as i get the time.0 -

So are most appliance technicians. Most of the guys around here just change parts until they get it right. I am one of the few in this area that can actualy diagnose a problem and fix it right the first time.
As for the 4-wheeler, It sounds like either one of the switches is shorted out or something is grounded. A good volt meter is worth its weight in gold in these situations( Ofcourse, knowing how to use one helps also[;)][:D])0 -

I have parked a running fine honda and when trying to restart it would not. Replaced the plug and it fired right up. Don0 -
first get a repair manual
I had a '00 Yamaha that had similar problems.
using the repair manuals troubleshooting list I found that it had a bad pickup coil which is part of the stator ass.
neither ign. coil or the voltage reg. provide the spark they simplify route it from the stator coil to the spark plug.
The battery only drives the starter and lights.0 -
Older wheelers have two induction coils under the flywheel, one for the charging system and one for the ignition system. The ignition induction coil might be bad. 0 -

Check the "kill" switch. And by that, I mean take it apart and check it. A lot of times they get stuck, dirty or damaged and cause a ground short. 0 -
I'm not a parts changer.... [8D] Is it a TRX200SX?
But that's usually a valid test! So if you have another unit to swap parts from, try the CDI box. It will be a 3"x2"x1" black box with two multi-pin connectors. Probably under the front fender.
Check the switches next. Kill switch on the handlebar should have continuity "OFF" at the black/white wires, no continuity "ON". The key switch should also have continuity "OFF" at the black/white wires, no continuity "ON".
With an ohm meter, check resistance on the wires coming out of the stator. It's behind the recoil starter. Should be a black/red, a blue/yellow, green and three yellows.
The three yellows are for the charging system. It functions independent of the ignition system. The yellows are probably in a 3-pin connector. The other wires will be seperate leads.
The blue/yellow is the pulse generator. It tells the CDI box (ignition module) when to spark. Should have slight resistance. Less than 100 ohms.
The black/red is the source coil. It provides electricity to create a spark. Should have around 300 ohms.
The best way to check the stator is by peak voltage output. But I doubt you'll find anyone with a peak voltage meter.
Does the neutral light come on?
Ignition coils RARELY go bad!
If the switches are OK, the coil and CDI box don't fix it....you have a stator problem. No electrical output to the CDI box. Ohm readings should verify that. Stator is probably sold as an assembly. A pretty expensive assembly. If it's still available!
Good luck! Hope that helps.
All that is assuming you started with a NEW CLEAN spark plug!0 -

I'd be more than willing to come to your house and help you Tazz, But the mileage is going to kill you[:0][B)]
I't would be a little bit easyier on your wallet( and my truck) if you find somebody local to help you[;)]
Although, I haven't took a vacation in probably 5 years, Maybe i'm about do for a vacation..... Hmmmmmmmm[:)]0 -
OK, TRX250. No suspension, doesn't turn too well? Yep, I remember those very well. A solid, bullet-proof unit. Just kinda primitive these days!
Should still test the same. All the wire colors, etc still the same as I stated. As long as my memory doesn't fail me!0 -

LOL, Tom, you sound just like my step dad.
Back in his day he was REALY big into motorcross( Has many many trophies to prove it) and he owned his own Kawasaki dealership. He'd race them, fix them, and sell them. He was VERY knowledgeable about troubleshooting and fixing kawaski motorcycles.
Its funny because now days when someone asks him a technical question about those old bikes the first words out of his mouth are always.... "Well, If i remember right"[:D]0 -
Check your kill switch, then your key switch then the stator. 0
