ENGINE START

1.Set charge rate switch and timer to OFF positions. (No timer on Model 2352.)

2.With the charger unplugged from the AC outlet, connect the charger to the battery following instructions given in section F.

3.Plug the charger AC power cord into the AC outlet, then move timer from OFF to HOLD position. (No timer on PS- 2352).

4.Set the charge rate switch to the engine start position that matches the vehicle battery and then crank the engine. Fol- low the duty cycle printed on the front panel of your charger for proper ON / OFF times. During extremely cold weather or when the battery is severely exhausted, charge the bat- tery for about 5 minutes before cranking the engine.

5.If the engine fails to start, charge the battery for 5 more minutes before attempting to crank the engine again.

6.After the engine starts, move the charge rate switch to OFF and unplug the AC power cord from the outlet before dis- connecting DC clamps.

Do not try to engine start a vehicle without a battery in it. You may damage the vehicle’s system. If the engine spins, but doesn’t start after several starting attempts, there is a problem with the engine of the vehicle other than its starting system. STOP crank- ing the engine until the other problem has been found and cor- rected.

CHARGE PERIOD

Determine the charge level of your battery with a hydrometer or electronic percent of charge tester. Determine the ampere hour rating of your battery. It may be on the battery information label. If the battery is rated in reserve capacity, convert to ampere hour rating using the following formula:

Ampere Hour rating

=

(Reserve Capacity) + 16

 

 

2

Example: AH rating

=

(168 Reserve Capapcity + 16

 

 

2

 

 

or AH = 100

Note: Reserve capacity is in minutes.

Use the following formula to determine the time of charge re- quired:

(AH x % of charge needed) divided by amp setting of the charger, times 1.25 = hours of charge

Example:

State of charge of the battery is 50%

Percent of charge needed is 100% - 50% = 50% (0.50 decimal)

Ampere rating of the battery is 100AH

Charger setting is

10 Amps

100 x 0.50 =

battery.

A hydrometer reading of the specific gravity of the electrolyte (fluid) of the battery in good condition should be between 1.25 and 1.28.

When a battery reaches 80–85% of full charge, bubbles will appear on the surface of the fluid. As the battery nears full charge, bubbling will become more vigorous.
