My friend has a honda prelude gen 5.

I don't really know much about Hondas so here was our conversation.

i know how to test most coils

mine is a little different

i know i don't have spark coming out of the coil

and there is a factory connection going into my coil

it has three wires

yellow

black with yellow stripe

and green

i am trying to find out what i am looking for from those three wires and at what times

keep in mind...

i use to have a msd system and i converted it back to stock

i didn't put the msd system in so i want to make sure i am getting the signals or voltage that i am suppose to to the factory coil


i dont really know what he is talking about so any help would be greatly appreciated! thank you.

 

A quick check of the ignition system is easy. Backprobe the blue wire of the dist connector with an LED test light. Check for a "ground pulse" while cranking. If a ground pulse exists, and a no spark condition is present, the coil is most likely bad. If a ground pulse is not present, you most likely have a faulty ICM "igniter."

 

okay i read verbatim everything you said. He says he has already tested the ICM and it seems fine. im gonna have to call him back again later and kinda repeat the first part. cause he didnt hear me. but thank you! any more input would be met with much thanks

 

it's usually the coil from what I've seen.
