Well guys in the end the company I ordered the coil from, had to send it back to Pertronix, because it is unusual for a coil to have a problem and Pertronix wanted to investigate, which is good. It would take 3 weeks, the company I brought the Pertronix coil from wanted me to wait 3 weeks until the out come was decided( a new coil or not ). Which is bad customer service really. As they could of just sent me another replacement coil, if Pertronix decided the coil was bad, Pertronix could of just sent another coil free or refunded the company money. If they decided there was nothing wrong, the company I brought the product from could of just sent the coil to someone else! ( which obviously there was something wrong )
Anyway as I was in the 14 day cool off period, I just asked for a refund and ordered another Pertronix coil from a rival company. The coil arrived today, and tested fine.
So now I am going to order some normal copper core ht lead, and also a racing ht lead with 40 copper strands, which is suppose to have a even lower resistance. Going to order a meter of both and then test the resistance of both, the ht lead with the least resistance will be used. The spark plug I am using is the NGK Iridium plug with a resistor. Should make for one strong set up.
