I finally started looking at a Frogger I bought a few years back. It had a blown fuse, I replace it, it blows again, I disconnect the monitor, it plays blind but doesn't blow the fuse.

I throw the monitor on the bench using my bench's ISO transformer after installing capkit, get a great picture.

I re-install the monitor in Frogger and it blows the fuse.

Could something be bad in the distribution box (where the fuse is located) ?

I did replace the plug as they had chopped off the ground pin...

Ideas?

Thanks
 
I guess tomorrow I'll tear apart the distribution box to try and see if there is anything obviously wrong.
 
Make sure you don't have A/C going to your monitor frame.

Ok, I'll take a look. I would have guessed that would cause all sorts of other issues if it were true. Hey, at least thanks for something to check. I've got a few other things to check on another project.
 
use a light bulb (60-100 watt) instead of a fuse and if it lights up you have a short some place. I do this but at a very low ac voltage (75 or 80 vac) so use caution as the light bulb will not blow where a fuse would. Be ready to pull power plug. Sometimes if the monitor is grounded it will blow fuses like that. Not sure about Frogger though. Second thought this might not be such a good idea if you haven't worked with monitors much.

Well, it was grounded - I honestly don't know if that was the problem.

I disconnected it but I also replaced the busted fuse. The one in there and the one I replaced it with were both fast-acting fuses. I replaced it with a slo-blo and disconnected the ground wire. Game fired right up!

For whatever reason, the picture was flipped upside down. So I don't know if the previous owner put it in there in an attempt to fix the fuse issue or what. I flipped the yoke wires and along with the capkit I installed the picture is gorgeous.

Kids are excited to have it working after they helped.
