Vendo V322-182

Hello, All! I have a 1970 Vendo V322-182 Coke Machine. Machine didn't work when I received it. Compressor is great! Fan runs fine! I replaced a few of the components on the Coin Mech (S75-9800B) and still no action (the Coin Return Electro-Magnets do not energize). I removed & tested the solenoids (CREMs) from the Coin Mechanism and they both function properly.
So, for the time being, I decided to bypass the Coin Mech by jumping the pins on the Jones Plug (if I remember correctly, Pins 1 to 7, 2 to 5, and touching leads from 3 & 7 together to simulate a switch). And, I temporarily rigged all the Actuator Switches on the Lock Out/Sold Out Assembly’s to be open in order to simulate there are plenty of cans in the machine.

When I simulate a switch by jumping the Jones Plug I hear, and see, the Timer Module activate in the Door Harness Assembly but nothing happens with the Relay inside the Door Harness Assembly.
1) Should I be looking at something other than the Relay?
2) If not, how do I test the Relay?
3) And any help regarding the Coin Mech would be appreciated, too.
