necting negative cable.
D. Check thatthe cover seal is notbroken away.Re-
place the battery if the seal is broken or leaking.
NOTE: Before connecting the negative (ground) cable
to the battery, connect a digital multimeter (set to DC
Amps) between the negative battery post and the nega-
tive (ground) cable connector. The reading should be
less than 0.1 amp. If the reading is 0.1 amp or more, the
machine’s electrical system should be tested for short
circuits or faulty components and repaired.
E. Check theelectrolyte levelineachcell.Ifthelevel
is below the tops of the plates in any cell, fill all cells
withdistilledwaterbetween theminimumandmaxi-
mum fill lines. Charge at 15 to 25 amps for 15 min-
utes to allow sufficient mixing of the electrolyte.
