Before moving on and plugging in the rest of the boards to my Mars, I want to make sure on a couple of things. I've rebuilt the mandatory parts on the power supply board according to Pinwiki, repinned 3 molex plugs that plug in to power supply, done the backbox ground mods (but not ran anything from the head to the bottom of the cabinet or messed with the interconnect harness), replaced the BR and caps on the sound/speech power supply, changed out the 3 BRs and the original orange Sprague cap in the bottom of the cabinet, and made sure all fuses are rated appropriately. I changed the orange Sprague with a 12000uf 25v Ritchey, the sound/speech cap with a 4700uf 63v Kemet, and all BRs with 400v 35a. Parts were bought from Digikey and GPE.
The mistake I made was wiring the BR on the sound/speech board wrong initially. I goofed, and since there was no clear indicator for pos and neg on the old BR, I decided not to look in the manual and assume I knew. Bad idea, but not catastrophic. When I rebuilt everything and powered the game on for the first time, after about 30 seconds the small 47uf cap blew. Pulled the board out, checked the diode and resistor in that area which were fine, then realized I had mounted the BR with negative where positive was supposed to be, and therefore soldered all lugs wrong. I've now soldered the lugs correctly, but is there anything else I could have damaged on that board? I would like to check before I plug it in again.
Also, I'm getting these voltages from the power supply board (with nothing else plugged in):
TP4: 5.1v adjusted with the pot (should I turn it down closer to 5.0v?)
Now I notice that TP1, 2 and 5 close, but not exact. Is this fine? I'm assuming yes because they're not under load/potentially could be unregulated but I want to confirm first. I don't have Fuse F3 (8a slow for controlled lamps) because I don't have any on hand, or any close to it like a 7a or 7.5a slow that I could just stick in for testing purposes. Doubt that makes a difference.
