Turn the key on and tap the white wire on the MSD box to ground kinda like doing morse code. Have the coil wire off the cap and close to a ground. If it sparks the MSD is ok if not the box is dead. You can also take the twin leads to the dist lose and quickly tap them together at the box and try that too, either/or will test the box. Make certain you have voltage going to the coil and box before you do that test.



Okay, weather got warmed up and tried the above.
1). Ignition key in ON position.
2). Took the White wire from the MSD box and tapped on an intake manifold bolt and at the same time, disconnected the coil wire from center terminal of the dist. cap and held it close to another intake manifold bolt.
3). Result: No spark jump from the coil wire !

(BTW, the white wire from the MSD box is connected to the black wire of the Pertronix unit. And the power going to the MSD box is directly wired to the POS. terminal of the battery.)

So.... Do I have a dead MSD box ?
