Hi Phil, Am taking the car feed from the end of the 50mm cable from the battery, where it bolts to the starter solenoid, this is also where the alternator feeds it's output and the headlight power feed is fed from.
I think I will test the resistances of the coils, they are all very old, well over 30 years, so it may be worth investing in a decent new coil. Can you even buy them nowadays? LOL
The wiring is all my own work, grossly over spec, there is no hidden ballast resistor lurking! With the battery accounting for almost 2 Volts of the 3 Volt drop there is little I can do about that, the battery is good, and spins the engine fast enough for ages if needs be, so there is plenty of capacity. I have another battery of similar capacity but I think the issue has been narrowed to the coil. Cool coil instant start, hot coil no start.

Reason: Clarity.
