Which one(s) of these switches/relays are keeping the motor running?

Quoted from vipertblck:

why not the "reset relay" too?

Because your original post mentioned the score motor as your symptom. If the Reset relay is stuck on, diagnosing that would be the next step.

Quoted from vipertblck:

500 relay is triggered by L or R stand-up switches...what are these switches?

Looking at this picture of the playfield, I see just below the left and right eject holes, switches behind rubber bands that are labelled "500"

What are the scoring relays (the 10, 100, 1000, or 10,000 point relays) doing when this happens?

Quoted from vipertblck:

im assuming that one of the scoring targets is my issue.

Unlikely

Quoted from vipertblck:

it just sticks the ball index relay on,

This is normal

Quoted from vipertblck:

except the 10,000, this one locks the relay on but doesn't advance the scoring reel

If the 10,000 Point relay doesn't activate the 1st player 10,000 drum unit solenoid, Inspect and diagnose this circuit with Alligator clip jumper wires
