Hi,
I'm new to the forum, and it looks like a great resource. I just picked up a Confidential Mission upright, but it has a problem. It keeps blowing the 5A fuse when i power it on, and I'm not sure what might be causing it. If I jump the fuse with a piece of wire, it turns on and starts to load. I don't really want to use the machine like this though, I figure there must be a reason it's blowing the fuse consistently. Any recommendations as to what I can check? Thanks for the help!

Re: Blowing Fuse
1st
Since you have already put a wire in and powered it up you could also try removing the wire and putting a amp-meter in series instead of the fuse to determine how much current you are drawing. I would not reccomend putting the wire in place of the fuse, replacing the wire with an amp-meter is basically the same as replacing the fuse with a wire but it will at least give you an indication of how much current you are drawing which could be useful. Again, I would not reccomend doing this. The decision to do this would be yours, and please be aware of any ramifications of doing so. I am simply providing you with the techical information on how to measure the current draw. Ideally you would have an amp-meter and fuse in series with each other.
2nd
To isolate the problem, I would start by unplugging all the periperals to isolate what is causing the high current draw
1) Unplug everything but the NAOMI MB and Monitor, power up and see if fuse blows or monitor amp-meter for current draw.
2) Power down then add one periperal at a time then power back up to determine which compent is causing the problem.
You have alot of periperals in the Gun Cab
1) GD-ROM Drive
2) Sound AMP
3) GUN i/o board
4) Left Pistol
5) Right Pistol
6) Flouresent light behind marquee?
7) IR sensor array
There are alot more (JVS I/O, control panel, more...)
I would personally start adding things in this order. Others might recoomend a different order. Not sure there is a given absolute correct order but you get the idea
(important, do not hot plug the peripherals, power down and then back up after adding each peripheral)
1) NAOMI MB
2) Monitor
3) GD-ROM
4) JVS I/O
5) Gun I/O board
6) IR Sensor array
7) Left Pistol
Right Pistol
3rd
Also there is a tech bulliten on the sauservice site stating to fuse the pistols as they did not come this way from factory.
Additionally there is a gun protection board that you should add in betweeen the guns and the gun IO board that costs about $35

Hope this helps and you get the general idea of how to isolate your problem

Well, I followed your advice and came up with the following. It looks like the Stereo Power Amp is what is causing the fuse to blow. Seems like this might have been a known issues by the previous owner, as the case had been taken off previously and was missing some screws. How would I go about testing it, and/or repairing the Amp? Would it just be better to try and buy a new one, and if so where could I buy one? Thanks for the help.
