Test Equipment
The following is a list of equipment recommended to test and
repair starter motors , and to test batteries.
Digital Multimeter
A Digital Multimeter is recommended. The meter may be
used to read volts, ohms or amperes, and test diodes
(rectifiers) when test leads are inserted in the appropriate
receptacle, Fig. 85.

DC Shunt
Use with Digital Multimeter. The DC Shunt may be used to
read starter motor current draw on 12 volt starter motors. Use
Briggs & Stratton Tool #19359, Fig. 86.
