Moon Patrol resetting with Arcade Shop Switcher Adapter. How should I go about fixing

I have a Moon Patrol with the Arcade Shop switcher adapter. The cabinet has all original wiring. The game is constantly resetting. You'll be in the middle of a great game and then BAM! it resets.

I tried a second working PCB and it is also resetting. So, it must be the power supply.

I tested the voltage AT the power supply screws with the game ON. Is that how I do this? They were all off a little. Which one should I dial in? +5? The green light on the power supply is on. It's a Peter Cheou. According the Power Supply, green means good +5.

Sorry, I am a switcher noob. How exactly should I test and where?

Thanks!
 
Put the black lead on COMMON and then the red lead on either +5v, +12, or -5v and see where they are. The adjustment is for the +5v although I've seen the +12 volt vary a little with it as well.
 
Your +5vdc on your switcher is failing. Turn up the +5vdc to read at least +5.1vdc, and reseat the edge connector.

Test again

Do you mean set the +5 to 5.1 with the PCB disconnected?

Thanks as always for the help.
 
Well, it appears that I fixed it.

While studying the wiring, I noticed someone wired the switching power supply to the monitor's AC which I am pretty certain is a major wrong since this is the monitors isolated power. So, for testing purposes, I ran the switcher to the service outlet on the bottom. And, well, it seems much better and hasn't reset once. I have played 5 games already and no resets. I couldn't get through one before without a reset. Also, my monitor is not going dim then bright like it was before. I thought I needed a cap kit. I think I was wrong. I think the monitor and the switcher were competing for power on that ISO line which must be wrong.

Since it seems good now I'll probably wire up the switcher to the marquee light AC so the power goes off when I turn the cab off. I read before this is a good place to get AC for the switcher. Right?

Oryk Zinyo did this recently to my Mad Planets and it works great. The +5V had gone out on the original power supply so a previous owner had installed a switcher to provide the +5V. He had to leave the original power supply in, though, because the switcher can't provide one of the other voltages Mad Planets requires (I forget which one).

Unfortunately, the previous owner didn't wire things correctly so the switcher was not behind the isolation transformer. The game worked fine, but the switcher was getting and putting out power even when the game's power switch was turned off. You had to yank the cord from the wall to get it to power down. Oryk wired the switcher to the marquee light AC to solve the problem. Works correctly now with no issues.
 
The isolation transformer can only handle so much power. Hooking a monitor AND a switcher up to it will cause problems. That iso will get finger burning hot and I'm surprised it didn't just short some windings or go open.
