R1 Menace: is cdi and ecu box the same thing? i found the ecu box on the oem parts list but not the cdi. i think its the same piece. my 4 stroke is only firing on two plugs. the coils where replaced and same issue. i switched the coils to see if one of them was bad but it was the location of the left spot that was not getting current through he coil. i assume its pre coil for the issue. the next item before the coil is the ecu box. someone correct me if im wrong. i dont want to fork out another bill on a waste of a part if its not the issue.

Gabriel Mundo: I have an atv that use to run flawlessly but now it doesn't. it turns over, lights work but it just will not start.

Tammie Satterfield: Max, I have to replace the cdi box in my older bike. I have been looking everyone I know, as well as friends looking for me as well. I have a 1985 Honda Shadow vt500c, and cannot find a replacement cdi box. I have seen a few on ebay, but one looked like trash, and the other "said" it "should" work for multiple years (but could guarantee fit). Do you have any recommendations?

Romelia Polly: I am sure that you will find good way to make it on Inplix Webpage.

Buck Ulrich: tape your battery ends do they don't short out your new CDI box,

DunePanda: ive just spent like 500bucks on trying to figure out why i wasnt getting any spark.....ended up changing everything from the stator, coils, relays, and the CDI i know how expensive these can get.....that haymeer you used, where can i pick that up? i cant find it on ebay.

Dean Jex: iv got a ram100 quad it got a spark but won't start tryd fuel down the head but still no joy any help would be great

dan smith: This is Not a CDI box-I've taken them apart. They are simply an electronics points eliminator.   A CDI requires a large cap, say, 1 or more uF, between coil minus ("") and ground.   It is charged to about 200 volts, then discharged into the coil. These contain no such large cap anywhere.  I've been an electronics tech 34 years, 17 years experience, plus several years as a hobby building hi voltage devices such as  Tesla coils, and externally driven coils, flybacks,  etc, to make sparks.

Aaron Bates: I dont know if I will get a response, but it would be great...
So I have been trying to get a 1973 yamaha ct1 175 running, and I changed the points, set them, I changed the condensor, and I have a low voltage spark. There is a spark there but its not strong enough. I think it could be the coil, but is there any other things it could be?

Dmitry Litvinov: hello my bike which is 02 zx7r has no spark i checked if the coils gets electricity and i found that the coils gets positive only and they missing negative. i checked if it has bad ground but its grounded well. all the fuses alright also. What can it be?
