STARTER CURRENT DRAW – 12

VOLT STARTER MOTORS

300mV

(STARTER MOTOR MOUNTED ON ENGINE)

To check the amperage draw of a starter motor

mounted on the engine, the procedure is similar

to checking the starter motor off the engine. The

battery cable and key switch harness installed in the

equipment may be substituted for the test harness

shown.

When making this current draw test, it is important

to monitor the engine RPM, amperage draw and

battery voltage. On all 12 volt starter systems,

make sure the test is performed with the correct

oil in engine, and belts removed from the PTO

shaft. Remove the spark plug(s) and ground the

spark plug wire(s) using Ignition Tester(s), Tool part

number 19368. Also the engine temperature should

be at least 68 to 70° F (20° C).

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.

4. Rotate meter selector to position.

5. Activate the starter switch:

a. Note RPM on vibration tachometer.

b. Note amperage on meter.

6. If the amperage draw exceeds 100 amps and the

engine RPM is less than 350, it could indicate

a starter motor problem. Check the starting

system, such as the battery, cables, solenoid

and connections. Then proceed to check the

starter motor by performing the no‑load starter

motor test as indicated on page 8 or refer to the

Briggs & Stratton Repair Instruction Manual,

Section 7.
