So, my stable of mods on my ST Pro is continuing to grow and I am starting to have issues powering them all.

Right now I have a lighted speaker kit, lighted Enterprise toy, and illuminated flipper buttons. Pretty soon I will be adding a illuminated shooter rod as well.

The speaker kit, Enterprise, and flipper buttons all need power off the main PSU by the coin door. I bought a 3-way 12v splitter from Mezel Mods hoping that would do the trick, but I can't seem to get all three mods power.

Right now I have the Enterprise ship plugged into the PSU aux connector. The ship has a built-in pass-through connector. I then plugged the 3-way splitter into the pass-through and then the speaker and flipper buttons into that. When I tried plugging the splitter first and the rest of the mods into that, the ship would not light up. When I tried the afore mentioned way, all three were working for awhile, but now it seems that the flipper buttons won't light up.

What is the best/correct way to handle a lot of mods that need power?

Yes they all work individually. Not only that though, they were all working together when I first plugged them in as described above(enterprise first, splitter into enterprise pass-through, speakers & flipper buttons into splitter), but at some point the flipper buttons stopped working. I have yet to try plugging those in alone to make sure something didn't happen to them.

I did some hunting around and came across the DK FTS-8 splitter board, which seems to be exactly what I need. Just ordered one from PinballLife.com, so I'll be giving that a try.
