Had a friend drop off a Bally Capt Fantastic "Home Model" pin to work on. The power supply had issues. His original issues were described as tripping the breakers for both left and right side coils.
Installed new caps and got my voltage back in line. Input voltage from the transformer is as follows:
Pins 1/3: 5.5VAC (5.25VAC Target)
Pins 7/9: 19.4VAC (18 VAC Target)
Pins 2/4: 5.5VAC (5.25VAC Target)
Now checking incoming voltage on the CPU board (or outbound from the Power Supply):
Pins 1/5: 18.2VDC (18VDC Target)
Pins 12/5: 5.01VDC (5VDC Target)
Pins 19/5: 26.2VDC (22VDC Target)
The main CPU chip has a new socket installed (OEM was the crappy brown style)
After repair, the display came right up and I was actually able to start a quick game. Before my 2nd ball, both slingshot coils locked on and so did the outhole kicker. Display went blank.
I suspect the previous issue with 5VDC being high, it may have corrupted the CPU chip.
Any suggestions before I spend $90 on a CPU chip? For reference, this is NOT my pin and I'm trying to help a friend out. He likes pinball but cannot afford much more than the home models.
