Cruis'n USA PSU replacement

(1/2) > >>

Jollywest:
Hi,

I have recently aquired an Upright Cruis'n USA arcade, it's complete but non-working and untested.

I checked the PSU and the fuse had blown, I replaced this but it just blows everytime I change it.

I was going to order another PSU but I when I checked the Happ PSU ref page HERE, I noticed that the PSU listed for Cruis'n USA there does'nt match the one I have in the cab. (See attached photo)

So should I go for a like for like replacement (which I don't know ever worked) or the one listed on that site?

that is a straight up starned switching psu for video game's
just do yourself a fav and match the 5volt current

but before u go any futher which fuse is it dumping ?
the 1 in the psu or the 1 that is in the ac group ?
what i am getting at is there could be other unerlying thing's causing that fuse to blow,excessitve current draw on the psu would be my first thought
if it ia the 1 in it

Jollywest:
Yea its the 1 inside the PSU, 250V 4A

What could be causing the excessive current draw then in this case and how could I test it?

BobA:
The PSU you have in the cab is a generic switcher that is usually lower powered than the one that Happs recommends.   The one from Happs looks to be a 200w xt ps just like used on older pcs.   You could power up the PSU in the cab without the load of the board and see if the fuse still blows.

Most of those "SMPS in a box" seem to shut down if overloaded rather than blow the input fuse.  A blown fuse, especially if it's immediate upon applying power or "blown hard" with blackened glass, probably indicates a fault on the primary side of the supply.  Fair easier to just replace the thing than repair it for most people, especially given that they're fairly cheap.

You could try running it with just a dummy load such as a 10 ohm, 5W resistor on the 5V output.  If it runs in this configuration, there is indeed a problem with an overload.
