Dead speedo on '89 740 700 1989

Hi,

My speedo died today on my '89 740; it had always worked fine and now is completely dead. I pulled out the dash and everything seems to be plugged in correctly etc. Also the odometer and tripmeter still work. Can anyone tell me which of the wires on the back of the dash connect to the speedo, and what voltages are normally expected from the sender unit so i can try to test it? Also, where should i look to check the connections at the sender unit?

Thanks!

Brad
