Forgot to connect the Iso Transformer
« on: June 30, 2012, 09:17:24 am »
It's been a few years since I messed with my arcade stuff, and I had a 13" monitor I wanted to test, so I connected it to a mega touch table top, and saw a flash of light, and nothing else, is it toast or did it just blow a fuses I can reset? Wells Gardner model 13K7801, also where can I get the fuse, I looked at it and it is blown, can I pull one from another arcade monitor as long as it's a Wells Gardener?

You definitely blew the fuse.  You can replace it with anything having the same ratings and the same formfactor (physical shape/size).  There should be something written in the fuse like: 7A 120V or 5A 250V SB.  The SB is slow blow, and it's sometimes notated other ways.  Take the fuse to a Radio Shack or something, and hopefully you can find somebody competent enough to match it.

There's a good chance you blew up a few other things in the process, but you may have gotten lucky.  Get some extra fuses to perform the inevitable troubleshooting.  The voltage regulator would be the next main suspect.  You'll also probably want a multimeter if you don't already have one.

I saw 15A 250V, so I guess I'll check some old monitors. Or if I can go to radio shack I will just get one there.

GOOD LORD!

15A is WAY too much for a simple monitor. Even big 27 and 32 inch monitors only have a 3 maybe 5 amp fuse.

you are sure it didn't say 1.5A ?

if indeed this had a 15A fuse in place of something much much lower and has been toasted by not being isolated it's HOOPED! You will be replacing a few parts for sure.

Yeah it probably is 1.5, I thought it was a scratch, so I wasn't really sure thats why I posted it.
