Zed Head Posted April 30, 2014 Share #13 Posted April 30, 2014 I don't think that Pertronix even considers the Z cars as a market anymore. You have to search for an Ignitor by distributor number and none of the numbers I've seen listed for 240Z's show up. I checked the two FSM's that are available on the web.Also, if you open any of the instructions for the Ignitor I kits you'll see that one of the first statements shown is about leaving the key on. The Ignitor II is more like the stock 280Z module or a GM HEI module in that it has circuitry to prevent overheating, probably some sort of timer that cuts current if there's no action within a certain time. I'm guessing from previous reading. Plus they took out the warning about leaving the key on. The II also has "dwell" (current) control like the GM HEI and the stock 280Z modules. Plus you don't have to worry about resistors or ballast, just get a low resistance coil. If I was going to use an Ignitor, I would find a II that works. How you find one though, is the dilemma, if it exists. The Ignitor I is old technology but I guess place like MSA will keep selling as long as people keep buying.JEGS seems to think that this Ignitor II fits a Z distributor although the Pertronix site doesn't. It's a problem.Pertronix 91761 Pertronix Ignitor II Kits - Free Shipping on All Orders @ JEGSIgnition Products Link to comment Share on other sites More sharing options...
jalexquijano Posted April 10, 2015 Share #14 Posted April 10, 2015 (edited) my 1972 240z has a pertronix ignitor system and 3.0 flamethrower coil are connected through the Ballast Resistor. I dont see any problem connecting it through the ballast resistor as other people have advised. How do i find out if this coil is working perfectly or if its weak?

Jim McKinney Posted April 11, 2015 Share #15 Posted April 11, 2015 Hello all, first post here - and I have searched for roughly an hour or so, but I hope you guys will be able to answer my question quickly. I have the pertronix and flamethrower combo and wired it like you diagrammed above with the ballast resistor out of the circuit and its working wonderfully. I bought the car on saturday and the BR was wired in....and it ran very very poorly. My question is, now that I have it running well, my tach does have a little trouble over 5k or so, and I want to install the MSD 9820 Tach Adapter, but all of the diagrams I see for it refer to folks using the MSD 6A system, which I don't believe I have. Using this diagram you posted, where would I wire in the tach adapter? Thanks in advance! -Jim Link to comment Share on other sites More sharing options...

My car is working though!! Just want to be sure! 1 Link to comment Share on other sites More sharing options...
