Is there anything that looks like a potential issue with the boards pictured? I'm an EM guy and would have to have a tech go through this.

Many thanks

On the last picture, second fuse from the left looks suspicious.

I was thinking the same thing. Have you checked voltages at the rectifier board? Also: from what i gather, the connectors between the head and cabinet have a tendency to corrode/oxidize on these games. I know in my Sharpshooter there were several connectors that had some dull pins and some with a green-ish corrosion covering the pins. I ultimately wound up re-pinning all the connectors between the backbox and cabinet.

Also--you'll want to clip the battery off the mpu board as soon as possible. A memory cap can be installed in place of it. (Look up the procedure for that though, not sure if any jumpers need to be run or anything like that)

Get that battery off the cpu board right away. Your boards actually look to be in pretty good shape.

I did a search for the memory cap replacement. The Panasonic Super Capacitor was recommended and was rated at 1.5 farad, and 5.5 volts. Would this be a standard application for pinball battery replacement? (I'm referring to the rated values of the capacitor)

Yep. It's what I use on my Cyclopes. As long as you turn it on for 30 minutes every month you should be fine. https://www.greatplainselectronics.com/proddetail.asp?prod=CERS-1.5F-5V&cat=67
