Battery Charger Test
On-Charge Voltage Test
Hydrometer Test
Discharge Test
Vehicle not operating to expectation.
Reading of 6 amps or more.
Fully Charge Batteries.
Reading below 6 amps and on-charge
voltage above 56 volts.
No apparent problems.
Possible old batteries.
Go to hydrometer testing.
All readings above 5.25 V and within 0.5 V.
All readings below 5.25 V but within 0.5 V
Check electrical system and charger
for problems.
SeeTroubleshooting Guide
If problem is not found, go to
on-charge voltage test.
Any reading below 5.25 V and not
within 0.5 V of those batteries
above 5.25 V, replace battery.
Replace any battery with a variation
of more than 50 points of specific gravity
between cells or has a cell with no
reading at all.
Entire battery set with specific gravity
readings below 1.250 is being
consistently undercharged.
Evaluate charging practices.
If discharge time is 60 minutes or
more, problem is not with the batteries.
If discharge time is less than 60 minutes,
replace all batteries below 5.0 V.
