So, we planted a lead into the 'tach output' in my MSD 6a box, and had no signal. I ended up wiring the tach lead from the coil +, and now I have a working tach.
I always thought that was a tach - thing. Am I going to end up killing a component having it wired the way I do? Car starts, runs and idles fine, even under a load....(Yes, I have the MSD instructions, and tried that first)
