Once again, thanks heaps for the help.
I could only locate 2 amps in the truck. One below the VM and one on the back corner left hand side behind the lift motor.
They do have LED indicators on them not lit.
Amp behind the lift motor was at 2.0V at B+
Amp below the VM was at 5.1V at B+
After unplugging the amps and keying on a few times still no lights on the amps, now occasionally getting error code FN and G4.
If the last 2 relays are removed then stepping on the deadman will make the middle contactor click on and the steering work.
