RPM activated switch
I installed a RPM activated switch on my dragster, since I have a electric shifter with a spring loaded solenoid. But after I installed the switch my tach quit working. If I disconnect the power wire from my RPM switch my tach works. Has anyone run into this or do I have a bad switch.

Sounds like a switch problem, we just put a msd 8956 in the Biscyne to control the newly installed 200HP nitrous, and it didn't change/anything else electically. Do you have all the wiring diagrams for MSD? There is a download availably at their site for every wiring diagam, in a PDF format. I couldn't install a push bottom on their systems without that download ops:
