I want the voltage guage on the incoming line to the MSD unit so that I can watch the CRANK and the RUN voltage while driving. This is why I have the gauge hooked up to the small red wire. Once I get time to swap out the voltage regulator, I will see if that fixes the ammeter and my two volt gauges.
I made most of my connections with male/female connectors just in case I need to swap back to my other ignition system. But I am planning on running with the Street Fire box this Spring.

Thanks again for your help.
