H. OUTPUT SELECTOR CONTROLS
Switch #1 - Use this switch to select the 200 Amp Engine Start and
the 35 Amp Charge Rate. Switch #2 must be in the down position
(Select Position) when using Switch #1.
Switch #2 - Use this switch to select the 2 Amp position, OFF
position and use to select use of Switch #1.
The ammeter indicates the amount of current measured in amperes
that is being drawn by the battery. For example, In the 35 amp charge
rate a typical discharged battery will initially draw approximately 35 amps.
As the battery continues to charge, current will taper to 15 to 20 amps
at full charge. The Start area of the meter indicates a high rate of cur-
rent being drawn from the charger. When cranking an engine, the starter
motor draws upwards to 200 amps. The meter needle will be at the
extreme right side of the start area. Sometimes a battery for the first
few minutes of it’s charge will draw more than 35 amps, in this case
the needle may be within but not to the extreme right side of the start
area. The 2 amp charge rate (on some models) may indicate some
activity on the meter. The meter doesn’t have the resolution to display
this low rate.
I. ENGINE START
5. If the engine fails to start, charge the battery for 5 more min-
utes before attempting to crank the engine again.
6. After the engine starts, move the charge rate switch to the
OFF position and unplug the AC power cord from the outlet
before disconnecting 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.
1. Set charge rate switch #2 to the OFF position.
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.
4. Set Switch #2 to the "Select Position." Set Switch #1 to the
"200 Amp Engine Start" position. Set the charge rate switch
to the engine start position 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 in the 35 Amp charge position be-
fore cranking the engine.

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 Example: AH rating = (168 Reserve Capacity) + 16 or AH = 100
(2) (2)
"Reserve capacity is in minutes"
Use the following formula to determine the time of charge required: (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% (.50 decimal)
Ampere rating of the battery is 100AH
Charger setting is 10 amps
100 x .50 = x 1.25 = 6.25 hours of charge needed
10
+ 1.00 hour more if charging a deep cycle battery
7.25 hours total for a deep cycle 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.
