Fuse f113 blows on power-up.

Quick look at where this is I'm guessing I've got a bad bridge rectifier. I'll really troubleshoot tomorrow because I'm enjoying the olympics right now, but I'm guessing that's a good start.

A good chance BR2 is bad.

F113 is the 5v, right? Does the fuse still blow if you unplug the power to the CPU board?

Put in a new fuse and pull all but the looped red/blue white connector on the right side of the board .
If the fuse blows your bridge is short .

Why not simply do the diode test to BR2. Then you will know if it is bad or not for sure...

Thanks for the ideas fellas. Unfortunately I woke up with a stomach bug. Good thing I have Presidents' Day off.

Got a short across two legs of BR2, just as suspected. Someone has already replaced BR1.

Thanks for all the advice.

Replaced BR2 tonight with my newly aquired Hakko 808 desoldering kit. Turned on pin and at first it didn't start. LED's on the board came on, but the game didn't boot. I ended up putting a bad fuse back in f113. D'oh, not sure how a bad fuse ended up in my 5 amp new fuses. New fuse installed and it fired right up.

I had the exact same issue and did a quick search, found this thread and about an hour later my machine is up and running again.
I had a replacement BR on hand, did the switch and that did it.

Thanks, folks!

Saw that someone had replied to this old thread. Glad it helped you get your pin back up and running! What did we do before the internet?

Call a tech out and became a few hundred poorer

My T2 is blowing F113 on power up. How do I test BR2 to see if that's the cause?
