What's causing this DAC2 Test failure
I'd assume it's a D to A Converter
But can't find it in any book
Where do I look for this bad part??

Plugging the fault message into google yielded this as the first link:

------
'DAC1 FAULT" or "DAC2 FAULT" is generated when a cable from the Analog Signal port on the 5890GC is connected during the power-on self test.
To clear this Fault:
Disconnect the Analog signal cable(s) from the Signal 1 and/or the Signal 2 ports on the 5890GC and turn the power off and back on.
After the self test is completed, you may reconnect the Signal cable(s). The GC will now become ready to run after equilibration.

Where is this analog cable? Is there a letter code on it?

There is an access panel on the top right of the 5890. It can be removed by lifting up on the rear edge of the panel. Once removed, you can see the connection ports for analog signals 1 and 2.
