If putting in a coin doesn't activate the Start (S) relay, inspect and diagnose this circuit with Alligator clip jumper wires.

Quoted from troxel:

There is a violent spark coming off of motor 1A

There are 2 switches on motor 1A, Red&White/Orange&Blue and Red&White/Green&Yellow. Which one is it?

Quoted from troxel:

It's the top one, OR+BL.

It's just possible that the Motor 1A switch should be feeding current so check if it's clean and adjusted right. If so, try blocking these 3 circuits/switches with paper one at a time to see which circuit Motor 1A is feeding.

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

If you blocked all 3 connections and that Motor 1A switch is still sparking then you have a short somewhere in the Orange+Blue wire. That kind of thing could take some persistence to find.

How comfortable are you with EM repair and how good are you with soldering?

1) The first thing I'd try is unsolder the Orange+Blue wire from all its non-motor connections and see what happens then.
2) Next, guess the shortest route where the wire goes through the wiring harness and see if you can figure out what might be causing the problem
3) Last resort but guaranteed to work - trace the actual wire through the wiring harness

Persistence always pays off but if you'd like to talk on the phone, send your # in a private message.
