I don't know the wiring in an '82 but you can also check the thin puple and black ignition trigger wire at the back of the tachometer to see if it's shorted or something.

Also don't know if there is a "speed relay" rev limiter under the driver seat that could interfere with ignition triggering.

And if there is a factory alarm or aftermarket alarm maybe it could be interfering with ignition.

The 450 volts to the coil primary terminal is a quick pulse and the negative terminal eventually goes to ground after dissapearing into the wire harness so it may be hard to check on a voltmeter.

Run the coil primary wires directly from the MSD box when you install it.
