Title: Williams Switching Power Supply Question
Post by: FrizzleFried on February 22, 2007, 03:08:52 pm
This is likely a pretty stupid question,  but I feel it's always better SAFE than SORRY....

I just received a Williams Switching Power Supply conversion kit from Arcadeshop to go in to my Joust.   The instructions say "Locate the two wired feeding A.C. power to the monitor. At a convenience spot,  tap the two blue wires connected to the new power supply".

That all it says about the power input.  One wire goes to AC/N and the other to AC/L.  Does it matter which wire I "tap" in to for each or either can be tapped in to either of the monitor power lines?

Am I correct in assuming one means AC Neutral and the other AC Line?   Not sure... again,  better safe than sorry.

ac/n=neutral
ac/l=live
i think u.s wiring is black/white/green
u.k wiring is brown/blue/yellow-green which is live/neutral/earth
so i am sure you know which is live and which is neutral out of black and white as you live in the states ;)

Both wires hooked to the monitor power are PURPLE with yellow stripes.   BOTH.   The monitor itself has two black wires coming off,  one with a stripe.  Is the stripe side line or neutral?

Just talked to arcadeshop...they told me it doesn't matter which way I hook it up...but i'd still like to try to get it Line to Line and Neutral to Neutral.

i never really bothered that much what way round a/c goes,certainly after a transformer as its not important-don't worry about it
