nienberg.11 Posted February 4, 2006 Share Posted February 4, 2006 Guys, I'm running new NGK wires, new cap, rotor, plugs and an MSD Blaster 3 coil. The trouble is that my spark is pretty weak which may be the cause of one of my cylinders not firing. I tried swapping out plugs, wires, and coils, and that didn't help. I then tried connecting the coil directly to the battery, which still didn't improve the situation (although surprisingly enough the car ran the same with the ballast resistors bypassed). Do any of you know of a sure fire way to get stronger spark out of a mechanical ignition setup like that on the 280Z? Any advice would be appreciated. -Mike Quote Link to comment Share on other sites More sharing options...
big-phil Posted February 4, 2006 Share Posted February 4, 2006 When I put my Accell super coil on, it had weak spark sort of weak-strong-weak-strong, turned out the ground wire was loose(to the coil). That was with the 83 turbo dizzy though, but would'nt hurt to check those ground wires? Quote Link to comment Share on other sites More sharing options...
nienberg.11 Posted February 4, 2006 Author Share Posted February 4, 2006 Phil, like I said, I ran live and then ground directly from the battery to the coil with no improvement. Quote Link to comment Share on other sites More sharing options...
JMACH671 Posted February 4, 2006 Share Posted February 4, 2006 As long as your getting a full 12v to the coil, i would look at the other end, mabe take a test light and connect it to the positive on the battery and test the neg side of the coil (without the coil connected) to see if you have ground leakage, that could cause a partial collapse of the field withing the coil.

proxlamus© Posted February 4, 2006 Share Posted February 4, 2006 wonder if i have a weak spark.. still the n/a coil.. and its original Quote Link to comment Share on other sites More sharing options...
JMACH671 Posted February 4, 2006 Share Posted February 4, 2006 Maybe check for a good ground on the igniter, some of the models had an issue with bad grounds on the igniters, or they were just faulty to begin with. Hope that helps. Quote Link to comment Share on other sites More sharing options...
nienberg.11 Posted February 4, 2006 Author Share Posted February 4, 2006 JMACH, thx for the suggestions. What is an igniter though? Quote Link to comment Share on other sites More sharing options...
