Phase switch

New member to the group and in desperate need of help.

I've replaced the output jack on my '82 SB1000 due to a catastrophic hardware failure (it literally broke into 3 pieces). I did the work myself due to having separation anxiety with turning over my bass to a luthier. I am skilled enough to solder the part in, so I bought the part from a European supplier that deals specifically with SB parts. During the repair process, I found ALOT of poor solder points and the root of my buzz. Many burned sheaths from an earlier repair ('87ish I think). Fresh solder, clean wiring, and new parts led to a fresh, buzz-free sound that I hadn't heard in over years.

After replacing the output jack, my phase switch isn't working. I took great care to depopulate each wire one at a time and move to the new jack to prevent issues.
 
If you have a continuity meter you can check that the switch is working by checking for continuity on the appropriate poles as you switch it. If that is good the meter can be used to trace the bad connection. If you post on the Aria Club thread there is a lot of knowledge their.
