find the fault. Not so easy on a VME bus machine. Yesterday I noticed a
short across the large 470 ufd electrolytic capacitor near the battery of
the CPU board (270-1134-03). I desoldered the cap and it tested fine and
noticed that the short is across the vias of the cap. Since a schematic of
this machine is pretty much unobtainable I was wondering if another 3/110
owner out there would be kind enough to test the continuity across this
cap. Thanks.

I pulled the board out of my /110 and also grabbed the spare that has one of the video channels go out after a bit, on both of them the ohmmeter reads open circuit across that cap lead :(. On the plus side it might not be the board itself, as that capacitor is probably across the power planes, but there are a lot of other capacitors and stuff that you will need to rule out.
