Patches and discussion for Ensoniq VFX family

Hi. New to the group and wondering if anyone can help me. I recently 
acquired a free SD-1 that needed a battery replaced. The guy I got it 
from tried to replace it and couldn't. I purchased a battery and 
holder from Route 66 (helluva nice guy, btw) and I'm trying to 
install it, but I still get the low voltage message. I think my 
problem is that I'm not making good contact. The positive AND 
negative holes where the pins drop into don't appear to have a trace 
to anything. I've also noticed that there is a hole on either side of 
the positive point, just a little behind it. Is there supposed to be 
a resistor or something here? Now I'm not talking about the resistor 
in front of the battery- these are underneath the battery. Does 
anyone have any advice on making a good contact here? I want to make 
sure the battery is connected right, so I can determine if the 
problem is indeed something else. Any help would be greatly 
appreciated.
