Coil and electronic ignition question

[manny1973]

I own a 73 240z that the PO converted to electronic ignition. I have no idea what the system is. How can I determine what the system is? I think it's the orginal dizzy but not sure.

The car has a blue Bosch super coil. In the black dragon catalog it says this coil can not be used with electronic ignition.. Advise Please.

My car runs good when it runs but when it get hot it just dies. I wait a while and it will run again. It is not over heating and I have verified clean fuel filters, etc, At this point I can not drive it because of this issue.

My thoughts, wrong coil

or bad electronic ignition. Any ideas?

Post pictures of your engine bay/distributor. Be sure to include a picture of the distributor with the cap off, too.

trying to get a picture to post. What is the trick to posting the picture here.

Click on the Go Advanced button below this thread on the right side of the screen. After you do that, the advanced features should appear between the text box for a Title and the text box for the message. Click on the paperclip. That will allow you to upload files.

Can you post a picture of the other end of that split loom?

That's a Pertronix Ignitor. I agree, we need to see how it's connected at the coil, and what else is connected there.

WAG - the Bosch coil is overheating?? Maybe?

I see no ballast resistor, is that correct?

[manny1973]

Correct I'm told this coil does not require one. According to Black Dragon catalog it says this coil is not for electronic ignition.

While there appear to be several versions of the Bosch Blue, they all seem to be about 3Ω rated, and so you're right, they should not need a resistor.

That doesn't change the fact that something is overheating and causing the car to stop. There's really only two choices here - the coil or the Pertronix unit in the dizzy.

When the car dies - does it die all at once (like switching off the ignition), or does it start missing and coughing and then die?

Here's another thought - are you sure the problem is ignition? What fuel pump are you running?

[manny1973]

The car just dies like switching it off. It's a 73 with both the mechancial and elcetric fuel pump. I have another coil it is a Blaster 2 but I don't know the ohm rating for it so not sure if I should try it.

Do you think the coil is acting up. Why does Black Dragon say not for electronic ignition?

I'd like to try another coil before I change the ignition. What would you recomenend?
