So i got a moon patrol off the curb around the corner and well it doesn't seem to work. I have found the schematics and installation manual and printed them out but they don't seem to help me much.
So far i have fixed what i think were some problems with how it was wired to the after market power supply(has a +5v reads around 4.91v, ground, -5v, +12v reads about 11.49v) as it seemed that the +12v that should have gone to the PCB was a +5v. Someone also added in a coin counter that seemed to make the coin door switches +12v and that just didn't seem right. Also the new power box was spliced in before the power switch and I don't know if that is right (all the switch does it turn on and off the monitor is that all it should do?).
All i can really get it to do is go into the test mode or almost in to it. It seems to be telling me I have a lot of ram errors and i have no idea what chip or chips i would need to look at it goes from:
ram NG: E000: 01 08 all the way to ram ng:E7**: ** ** as it seem to go up one thing at a time that would seem to be some 800 errors and yet i don't know how to read the error code to find the chip or what is wrong with it.
Here is a video of me just scrolling the error codes by holding P1start and and when i hit p2start it flashes rom test ok
