What did the manual say about it ?

It says +12 volt secondary.

So things operating on +12 volt have stopped. Until you replace the fuse. If it blows again, until you repair your board.

There sure is.
F116 fuses the unregulated 12VDC.heres a pic that shows all of the fuses.
If it continues to fail, the likely cause is BR5, which you can test with a DMM. You'll need to remove the board.

No, depending on which lamps, GI will be 6 volts AC, feature lamps 6 volts DC, flashers get nuked with 20 volts DC. None of them are 12 volts.

Probably not, but I would solve this problem first and then go back to the switch matrix problem.

Hello-

From someone who learned the hard way when first getting into the hobby, don't let your original power driver board be your guinea pig for your first board repair. Sure that big BR looks easy to swap out, but the traces on the board and can be burned so easily with just one slip of the soldering iron. My first BR repair worked, but the I learned later that I basically ruined the board with my crude repair using a $30 soldering iron. Unless you are going to be doing a lot of board repair, it's not worth the time and effort to learn how to solder boards...at least in my opinion. At a minimum if you really want to learn how to solder boards, get an old board off eBay and practice for a few hours first before jumping into your first repair...it is definitely harder than it looks. You also need to make sure you have the right equipment...just a cheap soldering iron will not due.

I only have three machines, so whenever one of my boards tests out with a bad component, I just send it off to Clive at Coin-Op Cauldron for a full test and refresh. Not only does it fix your problem, it also proactively replaces weak components that are inevitably going to fail in the future...especially on a TZ.

You can get an aftermarket board for a machine, but you can't replace the original factory board if it is ruined. I leave all of my board repairs to the experts.

Thanks, Rob
