I'm installing a new Happ power supply in an old Frogger machine.....I've never seen this type of power supply before and am not positive where to hook up the wires on the new one? I don't want to $#% this one up. ;)

The old power supply has five screws to attach connectors to....
#1 is labeled +V (two brown wires attached)
#2 is labeled -V (Two black wires attached)
#3 is labeled FG (nothing attached)
#4 is labeled AC (two aqua wires attached)
#5 is labeled AC (one pinkish wire attahed)

My guess would be:
1. two brown connectors to the Happ +5V 15A (position #1)
2. two black connectors to the Happ -5V 1A (positin #4)
3. two aqua connectors to the Happ AC 115V (position #7)
4. single pinkish connector to the Happ AC 115V (position #8)

Am I correct? 2nd question is that there is no ground coming into the old power supply, nor is there any ground prong on the cord....is this normal and safe?

Thanks!
 
Well...it looks like the AC lines are clearly labeled. Once you hook them up and have a good power supply, all the others should be able to measured with any cheap handheld multimeter.

I would ground your incoming AC ground (green or bare) to the chassis of the power supply (mounting foot or similar).
 
Your # 2 is WRONG! The "V-" on the old power supply was the common (ground). These should connect to the "GND" terminals of the new supply.

Otherwise you have everything else correct.
