PROBLEM POSSIBLE CAUSE REASON/SOLUTION

Short or no start cycle

when cranking engine.

Drawing more than the Engine

Start Rate.

Failure to wait 3 minutes (180

seconds) between cranks.

Clamps are not making a good

connection.

AC cord and/or extension cord

is loose.

No power at receptacle.

The charger may be

overheated.

Battery may be severely

discharged.

Crank time varies with the amount

of current drawn. If cranking draws

more than the Engine Start Rate,

crank time may be less than 3

seconds.

Wait 3 minutes of rest time before

the next crank, to allow the battery

and charger to cool down.

Check for poor connection at

battery and frame.

Check power cord and extension

cord for loose tting plug.

Check for open fuse or circuit

breaker supplying AC outlet.

The thermal protector may have

tripped and needs a little longer to

close. Make sure the charger vents

are not blocked. Wait and try again.

On a severely discharged battery,

use the 20A or 30A Booster setting

for few minutes, to help assist in

cranking.

I cannot select a 6V or

12V setting.

The charger is equipped with

Auto Voltage Detection, which

automatically detects the

voltage and charges the battery.

No problem; this is normal.

I press the display

button, but do not see the

percentage of charge.

When rst connected to a

battery, the display shows

voltage only.

This is normal. The percentage

of charge is only displayed during

charging.
