Hello,

I'm currently restoring an old EM pinball machine, it's a Williams Cabaret from 1968.
The machine was working, but then I decided to paint the cabinet. So I took out the playfield and the mech panel.
After I was done with painting I put back in the mech panel and the playfield, turned it on, and it didn't work anymore!

This is what happends:
When I add a credit the motor starts rotating, some relays on the mech panel energize but nothing happends on the playfield.
So the first thing I did was checking the voltages coming from the transformer, but those are all good.
Then I checked the fuses, also all good.
I've checked the plug from the playfield to the mech panel and they are also good.

When I turn the game on and press the left flipper the lights should turn on, but they don't turn on.
The lights in the coin door also don't turn on.

My question is: what's wrong? Does anyone know how to fix this?

Thanks
