i have an 84 200s which i cant seem to get a spark from it. any help is greatly appreciated

 

What have your tryed so far? new parts ect?
Did you buy this trike this way or did it just stop running one day?
How did you confirm there was no spark?

Welcome to the forum!

 

this machine is a friend of mine.it ran and he broke the pull rope so i fixed the pull for him andthen went to start it and i get no spark
when i was trying to start it it didnt sound like the plug was firing so i pulled out the plug and help it next to the head. no spark i havent changed anything yet because i dont want to waste money on it if its not worth it thanks for your help

 

Hello everyone out there any help on why i wouldn't be getting spark in this machine would be greatly appreciated

 

Definitely worth fixing. I love mine. Buy a manual on ebay for $20 and go through the trouble finding section.

Probably open circuit. Have you tried the easy things? New plug? ohm meter to check resistance/continuity?

Have you done a search on this forum for "no spark 200s"? I bet this has been discussed 1000 times and the experts are bored with it.

 

Try another spark plug if no fire could be coil, stater or cdi.....I would also check for a broken wire or loose connection....

 

OK...no spark for a 84 200s....(big breath)
1. Spark plug..Use a "known" good plug. NGK DR8ES-L gapped to .024-.028in
2. Plug wire.. Remove the entire plug wire from the engine/coil...Ohm out the plug wire and plug boot together Then wiggle the wire while you Ohm it. If at any time it reads "open"...repair it or replace.(if good put it back on the coil)
3. Coil..ohmmeter set on RX1..
........A. From the wire plug on the coil to the mounting flange...0.2-0.4
........b. From plug boot to the mounting flange...3-5K
........C. Ohm from the mounting flange to a bare spot on the frame. If it doesnt Ohm out....clean the mounting area on the coil/frame
........D. Inspect the spade wire connection on the coil to make sure it is clean and tight.
4. Pulse Generator.. Under the cover marked CDI on the left upper of the engine
........A. turn the engine over and make sure the rotor spins with the engine
........B. Disconnect the wires for the pulse generator and Ohm them (RX1)..value is 20-30
........C. inspect the rotor pickup end (steel part), if it is dirty clean it with 0000 steel wool.
5. Kill swich.. Make sure it is in the "run" position. Remove the headlight and find the 2 wires for the kill switch. (green and black) they should Ohm out, wiggle all the wires to make sure it doesnt change; then put the switch to off and it should Ohm open.
6. Alternator (stator). Unplug the wires.. Ohm the black (one going into the stator) wire to a good ground (wiggle the wire to make sure it doesnt change....It should have some resistance if it is open...you have a broke wire. Do the same thing to the green wire. Pay close attention to where the wires go into the cover. I have seen a bunch that had broke wires going into the cover.
6. CDI unit.
...........Hold the CDI in your hand; looking into the plug; have the plug on the left.......there are 2 rows of 3 pins....top row from the left to right are 1-IGN 2-SW 3-EXT second row left to right.....4-PC 5-E1 6-E2
Like this
.......[ign][sw][ext]
.......[pc ][e1][e2] While you are looking at it
Here are the test points

Positive test lead - negative test lead- value
SW-EXT-O.1-20K
SW-PC-0.5-200K
SW-E1-0.2-60K
SW-E2-0.2-60K
SW-IGN-infinity
EXT-SW-infinity
EXT-PC-0.5-100K
EXT-E1-0.1-2.0K
EXT-E2-0.1-2.0K
EXT-IGN-infinity
PC - ALL PINS- infinity
E1-SW-infinity
E1-EXT-infinity
E1-PC-1to5K
E1-IGN-infinity
E2-SW-infinity
E2-EXT-infinity
E2-PC- 1to5K
E2-IGN-infinity
IGN-SW-infinity
IGN-EXT-infinity
IGN-PC-infinity
IGN-E1-infinity
IGN-E2-infinity

If all this stuff checks out ok....You will have to start Ohm-ing out wires in the harness itself.
That is the best answer I can give to check for a "no spark" condition...... Not one part of this was cut or pasted and my hands are tired now! [img]i/expressions/face-icon-small-happy.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img] Good luck. MIKE-H

 

Wow Mike

Is your keyboard smokin'?...lol That was some detailed info!

I did that a while back for the CDI on a 200X for a guy in this forum and came to the conclusion thats its easier for everyone involved for the owner just to buy a service manual. Its to hard to explain how to test a CDI so everyone will understand. Maybe I just don't explain things as well and as in as much detail as you.

The reason I did all that typing and looking up values in the book; when buckw3 said this............
I try to help out anyone in the trike forum IF I can. So I typed the stages I would go through for the most part........I figured the CDI test was probably a waste of typing time for most to read.......but it might help too......I'm pretty sure I got all the steps in there [img]i/expressions/face-icon-small-happy.gif[/img].... If this trike was in front of me I could pinpoint the problem is 20 minutes max.....It took me about 25 minutes to type it [img]i/expressions/face-icon-small-happy.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img]...(j/k)

 

buckw3...........did the book I typed help at all?
