In Reply to: Old Ford Cars Low Voltage at Coil? posted by Ltdford72 on March 19, 2001 at 10:16:50:
In most of the Ford motor cars with point type ignitions, there is a voltage dropping resistor in the line somewhere and may be hidden in the wireing harness thus causing lower voltage to appear at the coil. When cranking the engine the resistor is bypassed in the (start) position, then put back in the (run) position.
I have already converted to the Duraspark system and did feed it with full 12V thru an aux. relay and ran 3 years without a problem cooking it before going to F.I. Of course I won't say that there could never be a problem as even the stock systems go bad at times.
Hope this gives some extra insight that helps understand thing a little more.
Good luck.
