after all the struggles of re-wiring the aux harnesses (previous owner didn't even have the damn wires on the right pins) and re-capping one of the other monitors, I observed tonight that the right side on our Suzuka 8 Hours 2 was freezing up and then resetting, sometimes a few times in a row. it made a clicking sound too, reminiscent to what a relay sounds like.

this is the first time I've seen this happen, anyone familiar with what might cause this on a System 11 boardset?

as far as I know, harnesses are snug (this is the side that had the better conditioned of the two aux harnesses, just had to fix a couple wires) and if I'm not mistaken, I had the +5 voltage adjusted right last year, and for what it's worth, the game has been sitting for the greater part of the past year.

my fiance and I raced on it, and both sides of the game worked fine. reminds me of our Ridge Racer... seems to work fine, until it sits in attract mode for awhile, then the vid board tweaks out. gd Namco.

EDIT: apologize in advance if it's not System 11... can't keep damn Namco's boardset naming/numbering conventions straight

seriously, no one? lol I know there's some Suzuka love out there, cause I know you all have said you want one. ;)

what's a good voltage to look for? I could test at the JAMMA edges on each board, but what should the +5 come up as there?

and if it's worth mentioning, for whatever reason the previous owners had the +5 hacked to a pin that I believe would be the -5, and I undid that and re-ran the hacked +5 wire to the one that was cut for the other +5 pin.

I don't think this game uses those, cause the other side's JAMMA edge didn't have anything for the -5 or -12.
 
Swap a different PS in it. If the supply is flaking out and dropping voltages momentarily you will get crashes/resets.

Also, are there any self tests that you can run to test the RAM on it?
 
self test, I don't think so, not on this game. it has a brief thing that pops up when it powers on (which you don't normally see cause the monitors need time to warm up) but you only see it if the game actually resets, and it's really only up for like 1 second. probably just lists out the current dipswitch settings, I didn't read it up close.

I don't even think it did it today. I wouldn't rule out the PSU, despite me adjusting it once last year, and the game only sitting for the whole year. it's a big box Peter Chou, probably original, and with the equivalent to 300,000 miles on it. :) how the fuck did they get away with powering 2 boards with the same power supply btw? I guess for all intents and purposes it's possible to drop a couple screw terminal PSUs in, but I guess that's the reason those mammoth XT PSUs exist in the first place, to handle a bigger load.
