Ray, In a previous job we once built an ignition rig that used a coil and EDIS unit of a 6 cylinder Ford engine (wasted spark) that would drive 6 plugs. Mounted the plugs using some internally threaded tubing and large brass pipe unions with the plugs sticking out of a large metal box that housed all the gear. Made a clear perspex box to cover the 6 plugs. Had to build a simple trigger ciruit to fire the EDIS module but you could adjust the revs, and with the right module when the revs were low enough you could quite easily see the module go into repetitive spark mode where it would fire the coil upto 3 or 4 time per strike. Looked great when hooked up to a scope! Cheers Sean
