Ghostbuster Pro

[Steve Arnold]

Hi all, I have picked up a nice ghostbusters pro with a couple of faults.
when a game starts from power up it fires 2 balls out. after a few minutes it stops doing it and just fired that one. I will swop the opto’s with my GOT but checked these out on a camera and I can see all the opto’s are working but will swop anyway.

The other issue is the auto launch doesn’t work. Seller fitted a new coil and new node 8 board but when the solanoid wires are attached and game switched on, coil locks on and game keeps resetting every second.
Any idea what I can check for these faults? A new coil was fitted but still the same.

Thanks
Steve

I get the occasional issue of 2 balls at once. Not sure why either.

Ok 2 ball eject is now almost gone.
A good clean of opto’s and re seat of connectors.

Auto launch was a shorted transistor. Found faulty one and replaced. Now auto launch works.

Thanks
Steve
