Going to try to document my progress of my Fish Tales resto. I found the machine in a non-functional state. Let's see if I can bring it back to life.
This is my first pin of the 90's era.
So first thing is first I found that F114 and F115 were missing from the Power driver board. So I replaced the fuses on the PDB and the batteries in on the MPU and switched it on. Now there was a tiny bit of corrotion on one battery terminal so I clleaned it up. I inspected the board top see if there was any damage caused by the corrosion and I can see any but I will check that closer later.

For some reason the F114 & F115 check fuses issue is now gone (could be the fuses I put in haha) and now the message is about factory settings are restored.
I turned on the machine and I hear two beeps a gap then a final beep. I see lights are mostly not working on playfield and backbox but that can wait. The leds that are on on the power driver board are LED1,2,3 are OFF and 4,5,6,7 are ON. I then tested voltages on the TPs and the results are as follows: TP 1=14.92v 2=4.97v 3=0.61v 4=3.65v 6=73.2v 7=21.7v 8=16.22v.
there were a couple BRs in the coin hopper that match the majority of the BRs on the board but a couple have been replaced.

I think these BRs have been replaced too
C2 looks ok but I am going to start by taking out the PDB and testing all 5 of the BRs an inspecting C2 and C4 as I keep reading that they can affect 12v at TP3. How do I test those in situ?
I will replace these most likely and see if they fix anything. I have also been told that C30 can also cause issues for 12v. I will check that one too. Any advice?
