distributor advice please?!

Hi again everyone,

Now onto another problem. I bought a "Ready to Run" distributor - NOT MSD - and have discovered that on my 74 Pantera there is a resistor wire from the ignition switch to the coil. It apparently only lets about 9.23 volts reach the distributor. I am told that this new electronic distributor needs 12 volts.
My question is: Does the distributor need a constant 12 volts to run or does it require 12 volts only for start up? I have tried to source a switched source for 12 volts but when I crank the engine over the voltage drops below the required 12 volts, making it harder to start, especially when warm. I have tried running a 12 volt wire directly from the battery and it starts every time, no problem as there is no voltage drop at the battery. I do not want to take the wiring harness apart under the dash to search for the resistor wire, so I also want to know of another switched 12 volt source with no voltage drop (maybe power window fuse?) or should I run a separate wire with a fuse and a toggle switch directly from the battery? I am not a wiring wizzard by any means so any help would be greatly appreciated.

Thanks again,
Steve
