barakandl -- What about system 9s? I am repairing a blown Tip102, 2n4401 on Sorcerer as we speak. This shouldn't be!

Just had a specific fuse go out on one of my boards...

Thanks for protecting my pins!

Just installed one in a Firepower that's been shorting the 2amp solenoid fuse (that I put a fuse breaker on)

Thanks to your invetion -- now I know precisely who the culprit is, and I can keep playing... It's the top right pop. I moved the 2amp fuse breaker now to JUST the pop until I put in the time to figure out where the short is...

Now I gotta open a new thread to learn how to best troubleshoot a short in a pop bumper...

thanks!!!!!!

Diode replaced on top right pop (thanks to vid's suggestion) and now I appear to be golden on that pin -- first time since I got it over a year ago.

Your board made all the difference in the troubleshooting. Before, all the special solenoids died and I had no idea where the problem might be.

If you haven't put one of these on every WMS 3-11 pin you own, get it done.

Thank you x 9000.
