So I have just got a Tommy home and before power on I decided to visually check the machine over.
I have quite a few possible issues I would like advice on before powering it on.

1. The power driver board, does this look safe? - Or should I just buy a new board?


2. Is this old battery acid leakage? - Again do I need a new board?


3. Burnt GI connector I presume, safe enough but should replace along with installing LEDs?


4. Now some odd ones, any idea what this disconnected connector and the bare wires are for?


5. Yet more disconnected wires, these look like off a flasher, although why 3 orange wires and 1 black? Also one of the orange wires looks like it had a crimp mark on it.


6. Finally yet another couple of wires that are disconnected, any idea what this is for?


Any and all help greatly appreciated.

De powerdrivers look like that after a few years, if it works, clean it and keep it, switch to leds and xpin and it wont get worse.

As for the connectors, no idea but im sure a quick spin in the test menu will reveal whats missing..?

I would repin the power supply (both headers and connectors) and test it. Probably replace the logic filter caps while out of the game too. It should be ok if supply runs well and stable.

Replace all burnt headers and connectors, moving to LEDs will reduce current draw for the game as well.

As for the battery corrosion, that looks pretty severe. Not only will all the affected components need to be replaced, but you'll need a lot of time and a more advanced soldering skill set to save it. It can be done, but even though I have experience with this I would strongly recommend replacing this board for long term reliability.

My guess is the last picture (purple/brown wire) goes to the knocker.
