Watched the tutorials posted in this forum and thought that since my battery was replaced 3 years ago, I should go ahead and replace that one with a final fix of the capacitor on my Raven.
Got what I am very sure is the correct capacitor (5.5v 1.5f). Figured it would save a ton of desoldering and board removal hassle if I just snipped the battery off the board, leaving the little metal leads from the battery soldered as they were. I then soldered some wires to the capacitor and put some female pin connectors on the other ends of the wires from the capacitor. These slipped perfectly over those remaining old battery leads, soldered into the board.
I Put the negative wire to the unmarked lead and the positive to the one with the little + near it on the board. I let the game sit plugged in for a bit to make sure the capacitor charged. After turning the game on, the first bad sign was that all high scores and credits were gone.
Added some credits and turned the machine off. Turned it back on after 5 minutes and it shows 0 credits again.
I’m at a real loss. This seems like a pretty darn simple procedure! For what it’s worth, with the game powered on, and the capacitor unplugged from the board (so there is just the two bare old leads from the removed battery), I get 0 volts across the old leads soldered into the board. Shouldn’t I see voltage? How else would it charge the capacitor?
Any other thoughts or trouble shooting tips are welcome!!
