I an having a problem with my 440 kit. The last few times I have turned it on I get "dip 2 incorrect". I have not done anything to the game and it was working fine. I have taken the board out and reseated everything. I am thinking the PS. Anyone?
Thanks
 
So apparently the pbc set really needs a ground! About a week ago I took the boards out to fix a flakey sound connection from the multi kit and forgot to put the big ground strap back on the board set.
Let this be a lesson to ya all....always pay attention then you are taking shit apart to make sure you get them back together right!
 
Im bumping this because I am having this problem again.....
 
I don't believe it has anything to do with the kit. Exidy dips are not the best and can cause cold solder or broken switches very easily.
 
Guess it doesnt really say but this is the 440 multi kit I am having a problem with.
 
The kit scans the DIP switches on power up and does a self check to ensure they are set to be compatible with whatever board the kit is installed on, so either the DIP switch itself is intermittent, or there is an issue with the vintage hardware and/or it's interface creating an invalid return which "confuses" the kit into outputting a DIP setting for a different board.

That could still be related to the grounding issue, or voltage fluctuations from cold solder or a flaky power supply. Most likely it is not a kit issue; there are no known bugs or bug reports related to the DIP setting self-test routine.
 
Thank you for getting back to me.
Flipped the dip and got the same thing. Thinking I will put a switcher in it and go from there. Ive checked the ground now and it is good. I am getting just over 5 volts on the 68BO9
