Thanks Ian and Steve for your input.To say I am confused is a understatement. First let me try to clarify what I know and then tell you what I don't know.
The wire with the masking tape on it is the black wire from the EI in the dissy.
Two wires out of the loom both white, one I have identified as a live from the ignition key.Thats the one with the scotch lock on it.
The other which has a yellow tinge to it has a lucar factory fitted connector on it, it splits into two wires and carries on to another lucar terminal and then someone has connected that via a jump wire back to the Lucar with the yellow tinge to form a loop.
Please don't take this as correct.
Question one, can I cut of the rather untidy loop and then attach what I presume is the tacko wire to the positive connection on the coil.
That would make three connections.
Question two, If i do this should I then get a spark at the sparking plug provided i haven't cooked the EI.
Question three, if I still don't get a spark should I then fit a new EI which would mean taking out the distributor which doesn't look easy as I can't even see one of the mounting bolts.
Question four, knowing how difficult it is to remove the distributor can I just fit the new module and leave the pick up ring in place bear in mind they are not the same make.I have already bought a new power spark EI
Question five, can I sling the Delco distributor and fit a lucas one in this early engine which i presume is easier to fit etc
I know some questions will be unanswerable and if I didn't have electronic ignition getting it wrong wouldn't be such a problem I know you can buy a new distributor complete but they all seem to be with EI now.
