[VAC] Re: Control panel tank levels

[John Leggett <pklhead2@xxxxxxxxx>]

Per the schematic, I believe the panel button is to
energize the tank level probe rather than leaving it
hot all the time and consuming amps.  There is no
"test" function that I can see. Since I've never seen
this thing actually work I may be all wrong.  But it
seems logical that all the lights would be on only
when in water and they should each go out as the water
level goes down and they become exposed - the gauge is
only in 1/4 tank increments.  I am assuming they are
all coming on currently because the transistors are
all faulty and allowing the 12v current to pass thru
the lamp and into the collector leg then out to the
common grounded emitter side of the transistor,
regardless of the absense of a control voltage on the
base leg.  Seems odd that they would all go bad at
once, but I'm no electrical engineer and I may be
missing something here.
