Gottlieb QUICK DRAW 1975 2 Player - ABC Rollovers Problem

 
The Rollovers for the letters A-B-C did not cause those lights to go out. Rolling over one of these still scored properly, but the letter light's relay's were not activated. If I manually activated a letter relay, say "A" for example, the "A" lights would go out. (refer Video).

The 3 Switch stacks 1B('A') 2B('B') 3B('C') at the Sequence Bank had been wired closed. Removing the wire from these switches had not made any difference.
Checked and cleaned these switches but still could not get these rollover lights to turn off. All these relays would not energize.

1B('A') 2B('B') 3B('C') coils were not energizing.

The only relays energizing whilst activating the lane switches were the 50 point relay and the EE (Series) relay.(refer Video)
 


Much the same as 4 player version Fast Draw - Spots the centre ABC lights (which are'nt lighting at all)

Someone had fitted a Williams coil to 1B'A' and wired it up using flimsy electrical terminals - on removal of this coil to check it ,the wire broke off at the coil (refer pict) and was impossible to re-attach so I fitted the correct coil (A-1119) This did not solve the problem.

Noted the ‘EE’Series Relay had a A-9740 (20ohms) relay fitted - Should be a A-9733 (2ohm) relay. Fitted an equivalent A-9746 coil.
THIS SOLVED THE PROBLEM - Sequence bank relays all energizing and rollover lights worked as they should.
