I got a Pac-land converted from a Food Fight the other day that played blind. The smaller fuse was blown on the G07 that was in it, so I replaced that half expecting it to just fire right up (not that such and expectation makes any sense with my record of bad luck).

There was a pop and sizzle and I quickly unplugged it. It had blown the main fuse in the bottom of the cab.

I pulled the monitor and looked it over real good, couldn't really spot anything. After a while I decided to try it again with the help of someone watching to try and see if it had the same issue... this time you could hear the monitor come on, nothing popped or sizzled, but the cab fuse still blew. It took about 20 seconds to do so.

I have another monitor that frustrated me in the same way in my basement, when ever it's plugged in it blows a fuse in the cab. Now I have two of em.

Any ideas?

Thanks.

Reverse the AC input wires to the monitor. I had one drive me crazy for a few days doing the same thing. It wanted the Hot wire on a specific side and the Neutral wire on a specific side otherwise the main game fuse blew.

In "theory" it shouldn't matter.

It really shouldn't matter. You're powering the monitor with *isolated* AC. The output of the isolation transformer has no ground reference - and thus no polarity.

This game does have an isolation transformer, right?

Yup it goes to a transformer.

I'm pretty sure the flyback is messed up too, Jeff F was here and pointed out a little hole on the side.

Yeah. Any time the small fuse on a G07 is blown, you can pretty much be sure that the HOT and flyback are toast too. It's a very common problem. Flyback goes, which draws too much current and burns out the HOT, then fries the fuse.

I got my flyback from Bob today, replaced it and it's good to go. Now I need an empty pac-land cab because this one looks like horse poop.

Thanks for the advice.
