I have an SST that I can play for hours on its own without any issues. When I boot up my entire game room this game reset intermittently. My B/W games have the kahr.us reset protection otherwise my TZ on the same circuit will reset like crazy too.

I live in a rental and don't have much saying about the wiring in the house. The SST is on a brand new circuit that was wired when I moved in.

Anyone have had similar problems? I'm going to check the 5V circuitry and might rebuild the entire thing as outlined here: http://www.pinwiki.com/wiki/index.php?title=Data_East/Sega#Low_5VDC_and_game_resets

Thanks for the pointers. My 5VDC showed 5.08 at R114. I ran the game on its own and I could easily trigger a reset by hitting all three flippers. In other words the problem had gotten worse. At some resets I could see that voltage drop about .1V. I upped the pot to 5.10VDC and the game remained on and survived TZ having a LITZ running on the same circuit.

I did measure the 5VDC of the MPU to get a difference. Before reseating the connectors it read 4.95VDC and afterwards 5.03VDC. I have reflowed every pin on the powerdriver board a year or so ago but I guess this will be coming back from time to time.

Is it safe to run the game at 5.10VDC if it works for now?

Hey, thanks for the tip. Do you know any vendor that sell these in kits? What are the plugs called if I need to get them separately?
