I am getting a deviation meter fail during self test, it appears to be reading deviation fairly accurately even with the failure.
I am assuming this is a recap situation and wondered which board I should start with.

Try connecting the control head directly to the drawer unit, then jump 20-22 on the acc (other D25 connector) this will power the radio up, this will eliminate any issues with your home-brew cable.

If you have a Motorola PS that fan will run 24-7 If the radio is not booting correctly due to a problem with the SCM the PA fans can run continuously.
Go to the meter page and check on what the thermistor voltage is, normally around 3.5V fans will start to run around 2.0 to 2.3V
