Generator tray won't extend

[Greg Young]

Several potential problems here. But the first is that the generator tray won't
extend. I have re-filled the jack fluid reservoir as one of the HWH leveling
jacks had leaked. I replaced the genny battery with a new one as i was getting
<12V from the old one and it would not take a charge. Now when I engage the
generator tray switch I hear a click sound, like a relay, but no hydraulic pump
and no motion on the tray. Ideas?
