Give this photo a try. It is of a Genesis. Everything should be the same. That idle connector has a mate.

Here is a Raven photo. It might show things a little better. All brothers from a different mother.

If everything that is mentioned above checks out then the problem is likely the driver board. By the way, are your pins in good shape? Those edge connector pins fail easily. It looks like you still have the original cable running between your MPU and driver board. You might want to re-pin or replace that. Also make sure you replace or remove that brunt up coil before doing any additional testing. We already know that item is toast.

Glade you got it sorted out. Re-pin that cable while the parts are still available. They quit making replacement pins so the price is going up dramatically. It will save you future headaches. Everybody says Gottlieb pins need a ton of grounding mods. In reality it grounds fairly good on its own if the pins are in good shape. Enjoy.

I don’t have the manual for this one so I can’t tell you what those switches are. My guess is you have a couple fried transistors on the driver board or bad pins between the mpu and the driver board. The driver board isn’t that expensive if you just want to buy a replacement. Like 110 dollars at the Arcade Shop. Just be sure your pins check out on that cable before you apply power.

Do you have a manual? If so, what does the fuse control and is it the correct size? If you can, follow the wires back from the fuse holder. If it goes to the driver board you likely fried a transistor. The wires might also go to a stand alone transistor. If so, that would be the likely problem.
