Equipment To Test Stop Switches
The Digital Multimeter, Tool Tool #19357 or #19390 is
available from your Briggs & Stratton source of supply.
The meter may be used to measure Volts, Ohms, or
Amperes, Fig. 32.
Testing With Digital Multimeter
1. Insert red test lead into receptacle in
meter.
2. Insert black test lead into receptacle in
meter.
3. Rotate selector to position.
4. When meter test leads are attached to switch termi-
nals, and switch is in “STOP” position, a continuous
tone indicates continuity. With switch in “RUN” posi-
tion, no tone indicates no continuity (incomplete cir-
cuit). An incomplete circuit will be displayed as “OL.”
NOTE: Contact surfaces must be free of paint,
rust or dirt.
