MS8-29 blowing R570

If you remove/cut J304 on the neckboard, which side shows the lower resistance to ground? Compare with another neckboard if you have one.

Thanks for the help I looked over all the caps and they were all the right polarity but I made a mistake with c332. I mistakenly grabbed a 220uf 50V cause they are exactly the same size and put it in C332 I found it just now thanks to you. Hoping nothing else took damage, but by swapping out for the propper 10uf 250 all the measurements went to proper levels. By the way would you mind if I post on this thread another ms8-29 I have with a different issue? Or should i just start a new thread for that? Thanks a million.

Problem solved guys, once I swapped the cap the f902 fuse blew but it turned out to be they had the wrong fuse there. They had a 1amp fast blow when it required a 2amp slow blow, I swapped in the proper fuse and it works great now.

this is exactly why i hate inheriting someone else's project. you never know what shenanigans they pulled. many a time i've spent hours tracing a problem down to find out they subbed an improper part. at least the fix was easy and it wasn't over fused... then you end up patching up fried traces if something went wrong.
