I bought myself an Atari Airborne Avenger project. After cleaning up, getting the bugs out, reseating the connectors and replacing the fuses I got it to boot. Attract modes works (not all lamps work), it shuts off when opening the coin door. But when I keep the coin door sensor pressed I can trigger a coin drop, and can start a game but it does not eject a ball.

None of the coils work, no ball launcher, pop-bumper, or flipper. What should I check first?

Other question, I previously only worked on Bally/Williams machines, normally there is a long cable you pull up that goes to the head but I don't see that laying in the cabinet, how does the head connect or is it just doing nothing, no lights even, how does it open?

Thanks, but I hope it is something simple I can replace myself.
Too bad the Atari repair guide has no Coils section: https://pinwiki.com/wiki/index.php?title=Atari_Repair

Are there no Atari experts on Pinside?

Thanks, the bridge one measures differently than the others. But I can not find the Motorola MDA3500 (35 amp 50 volt) can I use the this one from Marco instead?
