How do you troubleshoot a 7AL-2 ignition box? Was working on the car rewiring the tachometer and I think a wire may have touched another wire and shorted out my msd box. If I put power to the tach it comes on if I unplug it from the msd, when its plugged in nothing. Also I should have power to the coil when the key is on right? Now I have no juice. Thanks for any help.
