coil datas
 

Hello
Would you give me the resistance values to test my CDI coil, please ?

Philippe,

Whenever you have a question on Porsche Electronics, chances are that "Early_S_man" has already answered it. Do a search with him as the "User name" and the terms you need to find out about.

Using coil and ohms, you will find this post:

This should have your answer.

What is the problem you are having?

thanks

My problem, is sudden engine cut off (2.7RS engine), i'll try to eliminate electrical or ignition causes, if you have ideas....

Hi Phillipe,

Lorenfb posted this on another thread (http://forums.pelicanparts.com/porsche-911-technical-forum/341881-do-i-need-replace-my-cdi-box.html?highlight=coil). It should help you with your troubleshooting:

Loren sez:

"The diagnosis of this problem should take at most 5 minutes:

1. Get ANY known good ignition coil.
2. Make sure that the center pin of the CD box has a good +12 volts.
3. Make sure that the CD box case has a good ground.
4. Connect one terminal of the known good coil to the CD box output.
5. Ground the other coil lead.
6. Momentarily ground the pickup lead to CD box which will produce
a spark each time. Make sure nothing else (points, special pickups)
are NOT connected.

It's that simple!
