PDF circuit diagram labelled Z94Rp, with no revision, brand or model stated in the name. At 899 KB it is a fairly compact set of sheets, and it may be an earlier or reduced version of the Z94RP documentation. Use it to follow voltage rails from the charger and regulators to the loads, check pull-ups and test points, and work out which part pulls a rail to ground. Compare the code silkscreened on the PCB before trusting it, since boards in one family often differ between revisions.
