Today I am going to show everyone how to install & wire in a bill acceptor in Williams WPC era machines that never originally came with a bill acceptor wiring harness installed or bill acceptor coin door. Please use common sense and follow good safety procedures. Be sure the machine is unplugged from the wall outlet before attempting this procedure.
Tools needed:
7/16" wrench to remove/install coin door assembly
Common slip joint pliers (for the squeeze taps)
Molex crimping tool for .093" terminals
Common side cutters
Wire strippers
Hacksaw
Parts needed:
1 Complete WPC coin/bill acceptor style coin door (with wiring harness)
1 Mars bill acceptor AC power & credit relay output harness (Mars # 01-12-139 or Happ Controls # 42-7057-00 or Pyramid Acceptors # 05AA0012)
2 Red squeeze taps (Radio Shack # 64-3053 or Home Depot SKU # 408604 or Gardner Bender # 15-2218)
