Hi guys, nice to meet you all.
I have bought a 1978 caby jag 4.2 series 2. The engine was out the bay.
I have rebuild the engine, and as upgrade, i decided to install a powerspark high ignition distributor.
From the engine harness, i connect the white and the white/blue wire to pos pin coil (ballast resistor eliminated). To the neg pin, i connect the blue/white/grey and the white/black from wiring harness.
By the side of the dist, red wire to pos, black wire to the neg. Negative ground is nected too.
With this, sometimes i have spark, sometimes, no. What is wrong?
Could yo be kindly to attach images about your ignition system wiring? My english is not so good, and a picture draws more than a hundred words.
Thanks in advance to all, guys.
