440 fresh rebuild starter grinding on flywheel?

[440roadrunner]

4-5v at coil MAY be normal. The way to check this is at the "key" side of the ballast

You can do this directly (check voltage drop) by.............

turning the key to "run"

Set your meter to low DC volts

Stick one probe on the battery POS (starter relay stud) and the other probe

on 69/ earlier, hook to the 'push on' terminal of the voltage regulator

on 70/ later hook to the blue field wire of the alternator.

You should see VERY little voltage. Anything over .3V (three TENTHS of one volt) means there is voltage drop in the ignition harness

Your top suspects are the bulkhead, the ignition switch connector, and the switch itself, and in rare cases the ammeter circuit.

yep. im getting close to 2 volts. i appreciate your help. im new to mopars been a ford guy for some time but couldnt pass up owning a RR as ive wanted one since ive been a little kid. about 6 y/o. so where is the switch at? close to the ignition key i would imagine? i also have a couple of extra wires that look like they go to alternator ( got a repro harness from M&H) its brown? and i have an extra blue one as well?
