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.
