a little background. I had to pull my engine in my 74 Z to retrieve a poly lock that fell into the block. (Ugh!). I know I was careless and did not have a rag in the lifter valley while adjusting the valves. After putting the engine back in the car, I’ve got it running fine with a little bit of valve clatter that I’ll adjust for. My problem is that my tach no longer works. I’m running a breaker point distributor 1112148 that has a pertronix 1 in it. I’ve connected the pertronix black wire and the external condenser wire to the negative side of the coil and the red pertronix wire and yellow wire and black wire from the wiring harness (these 2 are connected together from the factory onto a single connector) to the positive side of the coil. Engine starts and runs fine but the tach doesn’t move any more. I must be missing another wire from the tach but I can’t seem to locate any wires that are not connected. Tried a search but could not find anything. Anyone running a pertronix in a 74 breaker ignition able to help me out on how the tach connects to the coil? Am I missing another wire or do I need to look for a short or broken wire. Has to be something I’m overlooking or messed up reconnecting the distributor. Help please?
