Come over to this thread:
Read such inspiring quotes such as:
Quoted from RatShack:
Not permanent. I added one and it fixed resets, later added a color DMD and now get them occasionally during long sessions. The power section definitely still needs attention.
Quoted from EvanDickson:
Not a permanent solution. I've had 2 machines with the daughterboard that eventually started failing again, the solution was a proper rebuild of the power board (and the fliptronics board for good measure).
If you don't have the consider confidence and tools to do the rebuild, then the daughterboard is a great temporary solution tho.
Even Rob - the guy who built that "silver unicorn" that hasn't failed in your machine, yet - clarifies the board is not meant to be a fix to the reset problem:
Quoted from rkahr:
I first was alerted to your post late yesterday but watched from the sidelines to let others chime in, but now I'll offer a few thoughts... If you haven't already done so, I'd recommend a review of the technical details on my website: http://www.kahr.us/index2.html . Note in particular the last sentence in the summary section that includes: "The power supplies still need to be maintained..."
To start, the WPC Power Fix is a permanent fix. But remember, my Daughterboard isn't called the "reset fix", so it is most decidedly not a permanent fix for the reset symptom experienced in WPC era games.
It will fail sooner or later, and then you'll have multiple issues to fix, and trust me - you'll have a lot less fun of a time diagnosing two reset issues than just one.
My TAF pulled that random reset stuff with one of these boards installed. I got burned believing it was a "fix all, end all" magic bullet. It's not.
I ended up fixing it by diagnosing the circuit and fixing the faulty part of the circuit that caused the resets.
