Hi Guys,

I just finished up working out the bugs of my 551B KSU. The only issue I have is, I can not get the buzzers to work with out the extra wire running from the power supply. The person who sold me the system said one of the original wires broke off from the power supply connection to the block so they rigged it up to connect directly from the power supply. Would anyone know what wire that could be from the power supply connection so I can fix it. this is for the buzzers for incoming phone co line.
