TABLE 1

LOAD TEST

BATTERY CONDITION

Good (green)

The battery capacity is OK. The battery may or may not be fully

charged. Check the specific gravity of the battery to determine

the state of charge, check for an electrical drain or possible

charging system trouble. Recharge the battery to a full level.

Weak or bad, but

the needle remains

steady. (yellow or red)

The battery capacity is not satisfactory. The battery may

be either defective or not fully charged. Check the specific

gravity to determine which condition exists. If charging does

not bring the specific gravity to the full charge level, the

battery should be replaced.

Weak or bad, but the

needle continues to

fall. (yellow or red)

Schumacher Bt-100 Battery Load Tester Manual

The battery may be defective or very run-down. Release

the load switch and note the voltmeter reaction. Voltage

recovery to 12 volts or above within a few seconds indicates

a defective battery. A slow voltage recovery indicates a run-

down condition. For best results, check the specific gravity.

TESTING THE CHARGING SYSTEM

1. Connect the tester.

2. Start the engine and run it at 1200 to 1500 rpm. CAUTION: Stay clear of

moving engine parts.

3. Note the meter reading with all of the electrical accessories off. It should be

in the green “OK” band in the “charging system” scale (see illustration).

4. With the headlights and blower motor on high, the meter should remain in

the green “OK” band.

5. If the meter reads in the red band or outside the charging system zone,

trouble is indicated; most likely a defective alternator.

STARTER MOTOR TEST

This test identifies excessive starter current draw, which makes starting

difficult and shortens battery life. Perform the battery load test first, to make

sure the battery is in good condition. If the battery tests either weak or bad,

this test cannot be performed.
NOTE: The engine must be at a normal operating temperature.

1. Perform a basic battery load test. Note the exact voltage with the load test

on (see meter illustration).

2. Using the load voltage obtained above, see Table 2 or the meter face, to

find the minimum cranking voltage listed. If the engine is less then 200 CID,

use the next higher minimum cranking voltage. For example, if the load

voltage is 11.00, use 10.2 for the minimum cranking voltage instead of 9.7.

3. If possible, disable the vehicle’s ignition system so that it will not start. The

test works best if the starter cranks for 2 to 5 seconds.

4. Crank the engine and note the voltage reading during engine cranking.

5. If the cranking voltage is below the minimum cranking voltage in Table 2,

the starter current draw is excessive. If the starter cranks slowly, check for

high resistance or poor connections.
