No spark on 1984 ATC200ES, Help Please

[atctim]

Do not confuse the CDI box with the pick up cover on the side of the motor that says "CDI". Your CDI box is a black plastic box. It will be located under the gas tank and it looks like this

what is the thing under the housing marked "cdi" called? sorry for all the rookie questions.

well i have spark now and i got it running! no smoke and tranny seems real strong. i dont know what i did maybe the part of the head i was holding the plug against was too oxidized or something. i dont know. it has a miss in the throttle. one of the headpipe bolts are missing and the other one is loose so hopefully after i fix that my miss will go away. but im stoked for now.

That's great news! Anyone have a schematic for this model? I'd like to look into the neutral light thing.

If the battery is connected, and the neutral switch is disconnected, does it get spark, then?

ahh HA!
bingo another twist.

Since we know these 200 es models will run withOUT a battery, that means no neutral light no neutral safety switch activated etc etc (in theory) The neutral light might try to glow when you try to pull start it withOUT the battery hooked up.

If you read my previous post, mine would only fire if the neutral light was OFF.
Battery connected, neutrallight on? NO spark.

Battery DISconnected so obviously no neutral light..SPARK!

Neutral light on? NO spark

so now here's your question...I think the neutral light neutral safety switch just keeps the starter from spinning but now I gotta check.

Thanks

oh, I also heard the of you ground the neutral safety switch wire , it kinda bypasses it and will allow it to run or start or something but your neutrallight will always be on, even when its in gear. AND it COULD start in gear~~~~~~!!!!!!!!!!!!!!!!!


..but it bypasses the question of whether your neutral switch is messing you up.

[puggerton03]

when i sanded down the rotor and pick-up under the cover marked cdi i moved the rotor without pulling it over. could that be causing my miss? if so how do i get it set again? i dont have a battery for this anymore. i got rid of it because it was dead. when i pull it over my neutral light illuminates and when i put it in reverse the reverse illuminates without a battery.

[tundrawolf]

Dr. Joe, technically all the neutral light indicator switch does is provide ground to illuminate a light in the dash, and provide ground for the starter button, as a secondary switch for the starter system. Technically, in the case of the starter bypass relay, if you disconnect the neutral safety switch, you will not be able to use the starter motor, unless you permanently ground it, in which case you are right-the neutral light would always be on and you WILL be able to start it in gear.

Now, here's a question: Obviously without the battery you are on pull start duty, but with the battery and the light on, when you say you have no spark, is it by the pull start and electric start both?

Hi folks,

Having similar issues here. Can anyone tell me how to ground the neutral switch? I see one two-prong plug (yellow) and one single connector (red) leading up from the neutral switch. Which wires need to be grounded permanently to the frame?

Thanks!

[patco]

anyone know how to ground the neutral switch?

"Runs great for a minute or a day and then either starts immediately or won't start for an hour or a day or 2. Then it has spark again, for no real good reason."

Thats bad wiring/connectors. Electrical/electronic gizmos dont just stop and start working for no good reason.

I had the very same problem with my 84 200es. Sometimes it would start and other days it would not have a spark at all, it was the CDI "969" box. I changed it and it fixed it, ran perfect and started every time after that. The 1985 HONDA TRX125 ATV has the same CDI 969 BOX AS THE 1984 200ES BIG RED . """" one other thing!!! DO NOT ATTEMPT TO USE JUMPER CABLES TO START IT! THIS WILL DAMAGE YOUR CDI AND WIRING , A car battery has too stronge of a voltage. I beleive this is what happened to my CDI.

[cbx1170]

neutral light switch wire is light green ... and on many Hondas and I think this one had a red tracer line down it. Ground that and light is on all time and will start even if in gear. DO NOT sand pulser / magnets on advancer under CDI cover. Clean them. Contact cleaner derust / remove red rust oxide Scotch brite mayyybe. lube advancer bushings/sleeves. careful advancer can be assy 180 off. slightly tighten springs if needed.

Or go here and read its a little long but it works. "84 Big Red 200S Runs then looses spark" 2 wks ago.

I have jump started hundreds of bikes atcs atvs pwcs power products ALL BRANDS and never damaged any part of elec system OTHER than accidentally by stupidly reversing jump cables. the individual systems only draws what it needs, current wise, as long as the voltage is correct.

I dont see a voltage difference between automotive and ATV/utility batteries. I have used my Optima redtop to jump my 200ES many times with no issues. Correct me if im wrong, cause ill stop using it then..... lol
