Msd ignition box problems. After testing it it seems fine. You can also perform this test by disconnecting the two prong lead from the msd distributor to the 6a box. Msd explained in depth just how this occurs. Disconnect the msd white wire from the distributor points or the ignition amplifier. If there is a spark between the coil wire and the engine then both the 6a box and the coil are working which means the problem lies with the ignition pickup in the distributor. Car still isnt firing though.
So its not the first time but it seems ive got a box brand new from msd that doesnt work. Why the old box had no spark is beyond me. Rats speed shop kauai hi. I disconnected it completely and so far cross my fingers the problem has gone away. Remove the coil wire from the distributor cap and position the terminal so it is approximately 12 from a good ground. This creates a magnetic field that builds strength thanks to the help of the iron core.
It hick ups intermitantly like someone is quickly switching the ignition on and off. Took the old box that i thought was crap and hooked it up direct as well. In a typical factory style inductive ignition current from the battery flows through the thicker primary windings when the switching device points or magnetic pickups is closed. Next day it will start or sometime later. Occasionally it will not start altogether. A new box solved the problem.
Turn the ignition to the on position. Make sure the ignition switch is in the off position. The new box was purchased from summit. Tested it and voila got spark.
