Switching out a classic power supply with new updated one...need help....
Hey guys, well i am a newcomer to these arcade game, i was given a old 1979 electro-sport draw poker machine....its just old...i fixed it up with some new micro switches and bulbs...it works great...as i was searching for info on the machine i found a new version of my same machine in my area...i picked it up for 25 bucks....the monitor wasn't working on it. Its the Electro-sport 1983 draw poker machine. I downloaded a manual for it to get all the specs. Well, i started ripping it apart to find the power supply not even screwed to the cabinet....so when this machine got moved, so did the power supply. In this machine it was power supply/audio amp. I have MANY voltages going from this transformer to the audio amp. i have... 5v,8v,10v,12v,16v, and 2 supplys of 115v. I tested them all and found out the monitor feed was open.
Well, i want to replace this very old supply with a new updated on as i know alot of people say that a bad ps can cause havoc. Well looking at my diagram for wiring, i found the wires going to the pcb.
i got:
pin 1: +5v
pin 2: +5v
pin 3: Lamp power "A"
pin 4: Lamp power "B"
pin 5: n.c.
pin 6: n.c.
pin 7: Sense/reset
pin 8: GND
pin 9: Audio signal
pin 10: GND
pin 11: Lamp ground
pin 12: Lamp ground
I know the new supplys have 5 and 12v...i have a couple qeustions on it...on my pin out i have 2 supplys of +5 volts...why? Can i just jump a 5v to each out and just use the one supply from the new PS?
Also, on my lamp powers. Right not they measure 6vdc on both pins to gnd. But when the machine is on, some bulbs work and some act like they are needing power...i think i am only getting like 1.5vdc to the bulb on some...power supply?
I also am confused on the voltages i get when i test it from the lamp powers to GND...and then Lamp ground...going to ground i get 6 volts...going to lamp ground i get 16vdc? Why is that?
And if i get a new PS can i just use a jumper to power A and power B lamps?
I am just confused about the differene in lamp ground and GND....
And what is a Sense/reset?
Thanks for ANY help that anyone can give....
