What are the Motor and the E relay doing when this happens?

Quoted from lint:

does not reset the drop targets

Quoted from lint:

Motor is spinning and E relay is firing.

Inspect and diagnose this circuit with Alligator clip jumper wires

Be careful because this circuit runs on 120 volts

Since the drop targets don't reset during game play or reset, the most likely culprit is the outside switch on Motor 2C

Quoted from lint:

The Purple/Orange switch on 2C is open in this reset position

For a switch to work 3 things are necessary
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening
