Was it set on freeplay? Are there credits showing on the wheel? Fuses good?
Give the score motor a nudge by hand, will it run a third of a revolution?

Glad you got it running. I'm restoring an Ice Revue right now.

Replace that power cord ASAP.

I would buy an extension cord whatever length you want, buy a medium grade one not a cheap one, there will be more copper in a better cord. Clip off the end inside you will see where the old cord comes into the body. You can usually reach into the main box and retrieve the old cord. They are usually in pretty good condition being inside. Clip it off and pull out the old cord, push the extension cord into the hole and push it into the main body. You don't have to remove the back box. I solder the connection to the old cord leading into the transformer and put wire vices on them or taping up in some way. This will give you a modern longer cord and you can throw that old cord away. When checking those fuses be sure to use a slow blow fuse where called for. The game will run better if it is played often. The DG switches on Gottliebs are self cleaning and if something stops working just play it a few games and it will usually start working again. A lot of collectors will clip the wires off the hold relay and just wedge a piece of cardboard to hold the switch in the on position. Sometimes the hold relay coils will look fried and make noise. The old timers were afraid of fire and neutering the hold replay was considered a good prevention move.

Your Ice-Revue does not have a modern power cord with a ground. You should fix that and run some ground braid.
