okay...sorry for the confusion...sounds like the module box should be grounded well enuf.

Can you run a jumper from the battery plus to the coil + and at the same time, jump across the ballast resistor from one end to the other with a jumper? Then try starting it.

the second diagram on the page shows wring for a four terminal module http://www.allpar.com/fix/electronic-ignition.html
