Ok you ready for some tough love?
Convert it back to a dig dug. it would be easier than you think.
Ok , i know your not gonna.
SO...
You need to find out what SF board you have and what the edge connector gives off.
certain pins on a boards edge connector represent what wire controls what.
One pin may be for that service switch (next to the vol pot) another pin would be for that coin counter and so on.
find the speaker output wire from your edge connector or board (two wires that go to speaker) those go to the vol control you point at.
then from the vol control you go up to the speaker.
Lets start with the coin mechs..
Those pop out , take em out and clean em.. oil them lightly.
look for a release lever or two tiny phillip screws.
That volume knob is next to a service switch.. service switches access game settings to test modes.
the power switch is usually ONE wire (black) going to your power supply.
take the power coming in from the wall, snatch the black wire from the switch and interupt the current power supply with that wire.
so you are using the switch to split the black wire going to the main power supply.
That shit on the bottom of your cab you no longer need unless you are using it for an isolation transformer.
and isolation transformer powers your monitor.
If you already have a stand alone isolation transformer at the bottom of your cab , you no longer need the atari power transformer.
Those switches on your coindoor..
You will find a COIN wire coming off your edge connector or pcb.
the switches use that wire plus a common ground to trigger the coin mech switches.
you can share one coin wire with both switches but dont forget to ground them both.
You can take the bulbs to an automotive parts store and match em up.
They are either gonna be 12 v or 5 v. you can run a wire from your switching power supply to light those.
dont forget to ground those sockets.
