I inherited an X-Files pinball game because it wasn't working and it has been sitting for many years along with being moved a lot in storage. Tooling around inside i found pretty significant battery leak damage. Some traces were completely eaten away. I THINK I repaired all the traces, the first couple times I wouldn't get L201 or L200 lights to light up, after cleaning some traces up I was able to get L201 to light up and later L200 with some resoldering. (They use to flicker at a very irregular pattern, i assumed dirty solder work)

At this point I have L200 and L201 constantly on.

Upon power on, I will hear a boot sound, I will sometimes get a Sega display screen but then goes away. The L204 is in a constant on/off state about a 2 second cycle. I hear a relay trigger then L204 goes off.

If I understand correctly, if L200 and L201 are lit up the CPU board is good? The L204 can be triggered from a watch dog not being connected? I've checked the ribbon cable several times since the watch dog line is in this cable.

The play field lights also flash in cycle with L204. I believe all my power rails are working too. I tested them with a DMM and the fuses. The lights signaling the rails are also on.

This is my very first time tinkering inside a pinball machine I may just be missing something?
