Did voltage drop test & had none from ign switch, thru relay, to solenoid. I thought this was original starter but should have know better
. Replaced starter and Ford wire harness since it had been 'worked on' using cheap clamp style cable ends. New harness was only $60+. Checked for voltage drop after install of starter and harness w/o any drop, started (lot less noise) & buttoned everything back up.
stamp11127, thanks for your patience and stand on the voltage drop check 1st & not continuity
and for everyone's help.
