Cleaned the contacts on the score reset relays?

Check the last few pages of the manual, find the contact for your specific reel and make sure it's clean and making contact properly: https://www.ipdb.org/files/1072/Williams_1976_Grand_Prix_Manual.pdf

Does the game start without the reel being reset or do you need to put it to zero before the game will start?

Quoted from nocreditdot:

Thanks guys.. it was actually a cold solder joint where the wire attached to the switch. I cleaned all the contacts until found that. Feeling my way through my first EM project. Good news is cosmetically I will have a nice grand prix.

Very common on williams. Always give em a tug!
