Converted HEI? Billet Distributor? Crank Trigger? Wires hooked up correctly on the coil terminals? Running 12V to the ignition wire on the box? 383Stroker 01-07-2006, 09:39 PM well ive had the box for about a year now, but its only got about 300 miles on it. my set up is all msd, 6AL, blaster 3 coil, to a pro builet the stuff ran perfectly 3 months ago when it was last run, i had to park it for a little while because of some bent push rods, fixed those this week and now, i dont have any spark, i have tested everything but the box seem to be the hold up. how many volts do coils need to operate? the only think i can think of is to by pass the box and directly wire the coil? any thoughts? 77'/85'scottspecial 01-07-2006, 09:43 PM Did you put the miles on it and the set up had previously worked or is it a used box that you have just installed?

From what I remember they're pretty helpful. 383Stroker 01-07-2006, 09:51 PM Did you put the miles on it and the set up had previously worked or is it a used box that you have just installed? the miles are with everything, just sitting for 3 months seemed to have killed my ignition system? 383Stroker 01-07-2006, 09:53 PM Contact MSD's tech line. From what I remember they're pretty helpful. i plan on it, a place called american motor sports is down the street from me and is were i got it from, ill call them first and see if they have a way to test it. i was just checking to see if anyone here had some wordy reason for why my box took a crap? thanks guys! 77'/85'scottspecial 01-07-2006, 09:57 PM What all did you have apart when you fixed your push rods? I am assuming you had the distributor out, maybe you didn't get it back in correctly? 383Stroker 01-07-2006, 10:07 PM marked everything on the distributor well and on the harmonic balancer,so i know eveything went back the same, but yes i had the manifold off, i put a spark tester on the end of the coil and it shows nuthin. nor does the test light show the coil itself is getting power | |
