    GAH Van not working on Hook up



    We have a Mercedes sprinter with GAH unit it works fine when engine running but will not fire up when on hook up.
    Any ideas?

    Do you get anything happening? controller lighting up, fans running...ect

    Normally the road and standby operation both use the same electrical circuit, except on standby the mains probably goes through a transformer and a bridge rectifier. And the compressor might be powered at mains voltage.
