I have an Allied Leisure cocktail pin (called "Circa 1933). I have reset issues and the 5v power supply voltage fluctuates (drops to about 2 volts after about 30 seconds of operation). Anyway...I bought a Happ switching power supply (picture attached). I need help knowing which wires from the old 5v power supply go to which terminals on the new supply. If anyone can help me out. I am particularly stuck on where the 5v (-) out goes. Is that basically a ground for the 5v (+)? Should it go on on of the GND terminals? I'll also include a picture of the 110 v wires from th old poer supply. I'm wondering if the black and white wires can each go on one of the two 115V terminals. The green wire is the field ground (FG) I think.

Sorry for my lack of electrical expertise. I'm trying to get better.

Thanks, that gets me 80% of the way. I know where 4 of the 5 wires go now. The only wire I have left to confirm is the one shown in the second picture I posted (of the old linear power supply 5v section) that reads "(-) OUT". Is that going to go on the second lug from the top on the Happ supply (labeled GND)? Interestingly, the Allied Leisure schematic has it listed as "+5v RET" (while the board is printed with a (-) sign at that location). I'll include the schematic here if that helps.

Thanks in advance.

Awesome! Thanks pdman!

All done! Seems to be working fine. Time to play!
