2.
Conduct a hydrometer test of the battery electrolyte.
B.  If the battery has recently been charged, apply a
amp load for 15 seconds to remove the surface
charge.  Use  a  battery  load  tester  following  the
manufacturer’s instructions.

IMPORTANT: Make sure the area around the cells is
clean before opening the battery caps.
A.  Measure the specific gravity of each  cell with a
hydrometer.  Draw  electrolyte  in  and  out   of  the
hydrometer barrel prior to taking a reading to warm--
up the hydrometer. At the same time take the tem-
perature of the cell.
C. Make surebattery terminals arefreeofcorrosion.
D. Measure the temperature of the center cell.
E.  Connect a battery load tester to the battery termi-
nals following  the manufacturer’s instructions.
Connect a digital multimeter to the battery terminals.
B.  Temperature correct each cell reading. For each
10
oF (5.5oC) above 80oF (26.7oC) add 0.004 to the
specific gravity reading. For each 10oF (5.5oC) be-

low 80oF (26.7oC) subtract 0.004  from the specific
gravity reading.
G. Take  a battery voltage  reading at  15 seconds,
then remove the load.

CAUTION
Follow the manufacturer’s instructions when us-
ing a battery tester.
A.  Check the voltage across  the battery terminals
prior to testing the battery. If the voltage is less than
12.4
VDC, charge the battery before continuing with

  1. At only 700mm wide the Mini Dumper is even at home on tight access
    sites. No need to grunt, groan, and force the
    mower about the yard. The US will be getting a revised 2011 Jeep Wrangler but the diesel option will not be offered in the United States.
