This a Gottlieb, not Williams.

The first thing I would check is the Jones Plugs. You will notice wiring bundles/cables that connect the bottom circuit board, playfield to the back of the head.
There you will find the cables terminate to Jones Plugs. If they are corroded or not seated properly the playfield will not light and various other things occur.
Next inspect your power cord from the plug to where it connects to the bottom board.
Checking all fuses is a no brainer, they may be under the playfield as well as a master junction on the bottom board.

The Pinball Resource is the master supplier for Gottlieb, figure out your part numbers if possible and send your order by e-mail. Pay by check when the parts arrive.
Order a new rubber ring kit, a few boxes of bulbs at a minimum.
Look at ALL coils to determine if you need any replacements.
Good idea to get a switch adjustment tool, a points file/Flexstone, and a bottle each of Novus 1 and Novus 2.
That is a clean looking machine inside.

looks like there is an envelope there with the manual & schematics there should be part numbers in there

90% rubbing alcohol

a new ball as well

Hey RKip455 , where are you located? You might be able to get a person who knows add-a-ball games to visit. (And they could admire that nice jukebox, too.)

Keep at it. I started with EM’s, and found most of the problems were switches either bent or needing cleaned. You may also find that the old sockets sometimes don’t make good contact to the bulbs. For the reset, there has to be a cam in the bottom and of the cabinet. I always clean up the cam “points” to make sure they don’t have any rust.

Once you get it fully working, the best thing you can do is play it! It helps keep the contacts clean.
