WARNING

COVER

Remove rings, bracelets, watches, necklaces, and any other

jewelry before working around vehicle. Jewelry can catch on

equipment and cause injury or short across electrical circuit

NEGATIVE

and cause severe burns or electrical shock.

ACTERY

Battery acid is harmful to skin and eyes. Always wear eye

ABLE

protection when working with batteries.

BATTERY

BATTERY VOLTAGE WITH STE/ICE

Use STE/ICE Test #67 to test voltage of

battery. Or, connect multimeter to positive

COVER

battery cable and known good ground to test

voltage. Battery voltage should be 24 volts or

higher.

(a) If voltage is 24 volts or higher, go

NEGATIVE

to Step 3 of this fault.

(b) If voltage is below 24 volts, service

ABLE

or replace battery as necessary

(Para 8-42). Restart vehicle.

POSITIVE LEAD

STE/ICE TESTS ON STARTING SYSTEM

(1) Perform STE/ICE Test #68. Starter

motor voltage should test between 18

and 27.5 volts. If voltage is not within

STARTER

range, replace positive cable

(Para 8-42).

OLENOID

BOSITIVE

(2) Perform STE/ICE Test #69. Negative

cable voltage drop should test between

ACTERY

0 and 3 volts. If voltage drop is greater,

ABLE

replace negative cable (Para 8-42).

(3) Perform STE/ICE Test #70. Solenoid

voltage should test between 18 and

27.5 volts. If voltage is less, replace

solenoid (Para 8-3).

(4) Perform STE/ICE Test #89. Solenoid

voltage drop should test less than

0.3 volts. If voltage drop is greater,

replace solenoid (Para 8-3).

(5) Perform STE/ICE Test #71. Starter

current average should test between 0

and 250 amps. If current is greater,

replace starter (Para 8-3).

(6) Perform STE/ICE Test #72. Starter

STARTER MOTOR

current first peak should test between

300 and 1000 amps. If peak is not

TR01447

within range, service or replace battery

(Para 8-42).
