12 VOLT DC STARTER MOTORS
A performance test of the 12 volt starter motor may be
made in the following manner.
Equipment Needed
1.
A tachometer capable of reading 10,000 R.P.M.
2.
A 6 volt battery : 0.3 volts.
3.
An ammeter capable of reading 40 amperes.
4.
A 12 volt battery * 0.3 volts.
Connect the starter motor, battery and ammeter as
shown on the accompanying illustration. See Fig. 114.
Fig. 114 -Checking 12 Volt Starter Motor Performance
Insert the tachometer in the end of the starter motor and
activate the starter motor. A starter motor in good
condition will be within the specifications noted in Fig.
115. Disregard surge current.
NOTE: A 6 volt battery is required in some instances for
test purposes only. This allows R.P.M. readings to be
made on a lower scale. See Fig. 115.
If the starter motor does not perform satisfactorily, a list
is given to aid in diagnosing problems. See page 9 and
10.
NOTE: To test starter motor ON ENGINE, refer to Briggs
& Stratton #19236 VOA meter Instruction Manual.
