B. Temperature correct each cell reading. For each
10 F (5.5 C) above 80 F (26.7 C) add 0.004 to the
specific gravity reading. For each 10 F (5.5 C) be -
low 80 F (26.7 C) subtract 0.004 from the specific
gravity reading.
Example: Cell Temperature 100 F
Cell Gravity

Correction to 80 F 1.253
C. If the difference between the highest and lowest
cell specific gravity is 0.050 or greater or the lowest
cell specific gravity is less than 1.225, charge the
battery. Charge at the recommended rate and time
given in Charging or until all cells specific gravity is
1.225 or greater with the difference in specific grav-
ity between the highest and lowest cell less than
0.050. If these charging conditions can not be met,
replace the battery.
3. Perform a high–discharge test with an adjustable
load tester.
This is one of the most reliable means of testing a battery
as it simulates the cold–cranking test. A commercial bat-
tery load tester is required to perform this test.
Follow the manufacturer's
when using a battery tester.
A. Check the voltage across the battery terminals
prior to testing the battery. If the voltage is less than
12.0 VDC, recharge the battery.
B. If the battery has been charged, apply a 150 amp
load for 15 seconds to remove the surface charge.
Use a battery load tester following the manufactur-
er's instructions.
C. Make sure the battery terminals are free of corro-
sion.
D. Measure the temperature of the center cell.
E. Connect a battery load tester to the battery ter-
minals following the manufacturer's instruc-
tions. Connect a digital multimeter to the battery
terminals.
F. Apply a test load of one half the Cranking Perfor-
mance rating (see Fig. 25) of the battery for 15 se-
conds.
G. Take a voltage reading at 15 seconds, then re-
move the load.

I. If the test voltage is below the minimum, replace
the battery. If the test voltage is at or above the mini-
mum, return the battery to service.
Installation
IMPORTANT: To prevent possible electrical prob-
lems, install only a fully charged battery.
1. Make sure the ignition switch and all accessories
are off.
2. Make sure the battery compartment is clean and re-
painted if necessary.
3. Make sure all battery cables and connection are in
good condition and that the battery hold down clamp has
been repaired or replaced.
4. Lift seat and place the battery near its compartment.
Push the positive cable connector onto positive battery
post. Do not hammer; this will damage the battery. Tight-
en bolts with two wrenches.
5. Place the battery in its compartment and make sure
it is level and flat. Tighten the battery hold–down bolts
uniformly to prevent cracking or distorting the battery
case.
6. Apply a light coat of grease on all battery posts and
cable connectors to reduce corrosion after connections
are made.
7. Connect a digital multimeter (set to amps) between
the negative battery post and the negative (ground)
cable connector. The reading should be less than 0.1
amp. If the reading is 0.1 amp or more, the unit's electri-
cal system should be tested and repaired.
8. Connect the negative (ground) cable connector to
the negative battery post.
