    2nd post and already have problems ;-)

    After some investigation into the reason my '83 mondial was only firing on one bank it looks like I may have a faulty digiplex unit.

    We (my auto electrical friend, and me making coffee) came to this conclusion after much fiddling with flywheel /ignition sensors and the general mess of wiring under the hood. After disconnecting both of the digiplex box’s and plugging in one at a time on either bank, seems that only one unit will generate a spark and other does ‘jack’

    Any advice on testing/repairing the unit would be appreciated. Part number is MED 803 A.

    Opened unit to check for any dry solder joints, no luck there yet. Anyone with any feedback welcome.

    Also, any other thoughts on ignition setup and options welcome.

    Midlands, UK - based testing options would be great.
