    Tried on another forum aswell but didnt get any respons so I'm trying here aswell.
    Some issues with my Agilent E3633A power supply.

    Got error 718 comming up when I'm turning on the output. Display shows -0.014V/0.055A. But the actual voltage output climbs slowly up to 22ish volts, regardless of the output state.

    No errors when I'm doing the power on self test.

    I've replaced U25, U28, U35, U41 in the ADC. That fixed error code 632 (hardware test failed).

    Service manual with schematics attached.

    I hope theres someone with Agilent experience here.

    I don't know if this is the file you posted, as I don't want to download it, but page 76 on this service guide says:
    I'd say you should be looking at the output amps, but that is only a guess...
