    Thanks Garry.

    I tried again today – replaced the HT lead with another, cleaned the bottom HT lead and removed all and cleaned the armature plate. Checked the continuity & resistance of HT leads and re-attached the kill circuit. With no success.

    To re-iterate; new points on both, set to 020, new J4Cs set to 030, good HT lead on top cylinder, checked, with continuity and 7.01OHMs, old bottom HT cleaned up and 6.85OHMs, kill circuit checked for breaks, both new coils screwed properly into the HT leads. No evidence of any wires to ground..

    Am not sure whether what I call the ‘bugger up team’ might have been there before me.

    I think the only option left is to remove the kill circuit wires. Am left wondering whether this is a cusp motor at 1965 with a different setup, but nothing in the Seloc, Clymer or a pre ‘1969 35hp Intertech service manaul has any clues..
