Caused my SF Alpha to Suicide when changing battery
This was my first ever attempt to change a CPS-2 battery, and it didn't go well.
Please review my process, and let me know what I did wrong:
1) Tested game in cabinet immediately before moving to the next steps, to ensure it was still working before starting
2) Plugged in solder iron to start it heating up (60w)
3) Opened B board cartridge, removed game PCB from outer shell
4) Set up work area, bent new battery legs into position, to ensure a quick swap
5) Tested new battery - it tested good at 3.64V
6) Desoldered old battery, soldered in new battery. Made sure it went in with correct orientation (+ side inward, - side toward edge of board). Took 3 minutes max.
7) Tested voltage from - leg on newly installed battery, to a trace point on the board downstream on the positive side of the circuit. It measured out at 3.64V.
8) Re-assembled game, plugged it into a known good A board, then powered the game on to get a blue screen.
Did I do something wrong?
I've read that the capacitor that should be holding the charge for 20+ minutes could be buggered, and possibly didn't hold the charge. Of course, I didn't read this until after the botched swap.
