I've been working on a Pertronix install for a while on a 1972 that had a OEM ignition and need help. The car ran before the install but not after. Cannot get a spark out of the Flame-Thrower coil. I know this specifically, because I broke down and attached a long spark plug wire to the coil - held on - and cranked the engine. Nothing, not even a tickle. I was thinking I had the coil wired wrong, so I rearranged the wires to the coil a number of different ways each time turning over the engine. I really wish one combination would have been a shocking experience. Literally! I will be honest, I did have the coil wired wrong. I had the Pertonix Red wire on the Neg., and Black on Pos. If I've fried the module, I'll get to that in a bit. I just want spark out of the coil for now. I've been following this case, Pertronix Ignitor 1761 install and coil evaluation, from Akorns. I even thought the Flame-Thrower was bad and purchased a MSD 2 coil with the same results. Now, i do have lights: head lights and dome. Fan works, heater and Aux fan. Engine cranks over and over and over. But no spark. I did notice a little bit ago the Tach doesn't move with cranking of the engine as it did previously. Is there a fuse for the tachometer? I have just noticed a bad fuseable link with the starter. It literally came apart in my hand after installing a new battery and battery cables. Any thoughts or advise? Thank you very much, Sean
