I went to roll down the windows in my '91GL Westy today and no
juice;  I've just recently installed an Aux Battery kit as per the
instructions, and yesterday, I installed an Oil Pressure (dual)
sender unit and am wiring the gauge in the cockpit today.  Before I
even started checking which hot wire to tap into for the gauge power
I discovered that my MAIN Battery is completely DEAD and the AUX
Battery is showing only 4 volts or so.  None of my lights were left
on, key was not in the ignition, Fridge not on, etc...  Don't know
where to start to find this phantom draw.
