This is my followup to my thread yesterday as can be seen here http://forums.arcade-museum.com/showthread.php?t=148393
To recap, yesterday I while swapping PCBs on my 4 Player Konami cabinet, the machine decided to stop booting PCB's, and for some reason the coin door stopped lighting up as well. When I switch on the cabinet, I get a marquee light, I get static from the speakers indicating to me that they are on, and I can tell that the monitor is turning on as well.
Following the advice in the thread I posted yesterday, I picked up a multimeter to test my power supply. I have a Happ power supply that has wires in six terminals, +12v, GND, GND, +5v, AC/L, and AC/N. I put the black wire to the AC/N Terminal, and then the red wire to the +12V terminal and +5V Terminal, and both seem to be reading aproximately the correct voltage. Also, the light on the Power Supply is green, indicating that there isn't a problem. I am not an electrical whiz by any means however, in fact I'm just learning this stuff, so maybe I did something wrong.
So if the Power Supply is fine as it seems to be, what should I start checking next? It just seems so bizarre to me that I would lose power only to the Coin Door and possibly the JAMMA Harness, but not anything else.
Any help would be greatly appreciated, and please bare in mind, I'm just learning, so please don't mind my total ignorance. If there's any other information that would be helpful in diagnosing my problem, please let me know. Thanks.
Edit: Upon second look, it appears as though the Coin Slot is powered through the JAMMA Harness, so it appears as though it's the Harness itself that isn't working properly.
