A couple of days ago my '71 first series 240Z refused to start and run. Came with a Jacobs Energy Pak when I got it. Appears that the switch for "Computer" or "Conv Ign" is bad; it has 3 large cracks in the switch housing and "crunches" when switched from one position to the other.

Decided to remove the Jacobs and replace with something else. When doing this, I discovered that my L24 has a D6K82-01 distributor which I think is from a later (1983?) 280ZX. The module looks like an E12-92 in that it has 2 terminals on top and 2 on the side. I cannot locate anything on it stating it is an E12-92; just IGM-08 and made in Japan. Nothing indicating Nissan or Datsun original equipment.

Wired the distributor/coil, eliminating the ballast resistor and the car starts and runs fine (well at least after I couldn't get it to start until I reconnected the wire from the coil to the distributor!). I have had the car up to about 75 mph. Acceleration seems fine with no indication of pre ignition or other timimg problems, which I thought I would have if it is an E12-92 or aftermarket equivalent module.

Questions:

1. Can anyone verify what year/model the dizzy is from?

2. Any idea what module I have?

3. Just what good things was the Jacobs Energy Pak supposed to provide?

The E12-92 was used on the 82 & 83 ZX, as well as the 82-84 Maxima. You can get replacements for those at Rockauto.com. I don't know anything about the Jacobs system.

Hitachi and Denso made most of the electronic parts that I have seen. Here is an E12-92:

Note the Hitachi stamp/seal/logo/icon above the "V" in 12V
