NO‑LOAD STARTER CURRENT DRAW

12 VOLT STARTER MOTORS

300mV

(STARTER MOTOR REMOVED FROM ENGINE)

To check the no‑load amperage draw of a 12 volt

starter motor that is removed from the engine, a

xture as shown in the gure should be used. See

the diagram for the parts necessary to make a test

set‑up.

CAUTION: DO NOT clamp motor housing

in a vise. Starter motors contain two ceramic

magnets which can be broken or cracked if

the motor housing is deformed or dented.

NOTE: When checking starter current draw, battery

voltage must not be below 11.7 volts.

1. Install shunt on - (negative) battery terminal.

2. Insert RED test lead into v

receptacle in

meter and RED receptacle on shunt.

3. Insert BLACK test lead into

COM

receptacle in

meter and BLACK receptacle on shunt.

5. Activate the starter switch:

a. Note RPM on vibration tachometer.

b. Note amperage on meter.

6. Note starter motor housing length and refer to

Table 1 for test specications for starter motor

being tested.

7. If the starter motor does not meet the

specications shown in the chart, refer to the
