Re: 1972 does not turn over when hot

Ford fender mount solenoid from 70's-80's. The + battery cable gets moved from starter to input term of solenoid. Will need shorter cable. Run another cable from output term on solenoid to orig. location on starter. Remove smaller wire from starter, it now gets re-routed to "s" term on Ford solenoid. Finally, use a small piece of heavy guage copper wire (romex ground works well) and connect between battery terminal on starter and smaller start terminal on starter (where smaller wire was previously). I mounted Ford solenoid where junction block was on passenger inner fender. This modification allows full voltage to starter solenoid, virtually eliminating voltage drop in smaller start wire due to heat, age or whatever. I also like the fact the heavy batt cable is not "live" anymore, only when starting. If the Ford solenoid has a small "I" terminal in addition to the "S", it isn't used.
