Use a small Phillips screwdriver and a 5/16" wrench to remove the six screws that hold the
battery box to the back of the front panel on the Acoustic Fluid Logger, again being careful to retain all
six screws, lockwashers and nuts for reuse. Be careful to retain the lockwashers with the screws.
(Caution: A dropped lockwasher or screw inside the fluid logger could cause a short on the circuit
board during use.)
The replacement battery is a 12-volt 7.0 amp standard motorcycle battery. Place the battery in
the battery box, being careful to assure that the red battery connection faces away from the metal box, and
the black connection fits down inside the battery box. When the battery box is placed back onto the top
plate, the red battery connection will then rest next to the top plate.
Replace screws in battery box, pushing screw through bottom plate and through battery box, then
replacing the lockwasher and nut on top of the battery box side. Tighten all screws completely. (Note:
Screws are #6-32, 3/8" if replacement of lost screws is necessary.)
Reconnect the battery, making sure to connect the red battery connection wire to the red battery
pole, and the black connection wire to the black battery pole. Important: At this point tilt the box to
one side to make sure no hardware has fallen into the box and is lodged under the circuit board.
Remove any stray hardware to avoid shorting the circuit board.
To complete battery replacement, replace the front panel in the box, being careful not to cut any
cables or wires. To keep box size down the front panel and internal electronics are a tight fit, and must be
carefully slid back into position. Reassamble the unit, then reinstall the ten #6-32 1/2
"
front panel screws,
remembering to fit each one with a lockwasher.
