Equipment Used for Testing

Digital Multimeter

A digital multimeter is recommended for all electrical testing of Briggs & Stratton engines. The meter can be used to read volts, ohms, amperes, and to test diodes.

The Fluke® Digital Multimeter #19464 and the UNI-T® Digital Multimeter #19581 are available from your Briggs & Stratton source of supply.

NOTICE: The digital multimeters are equipped with fuses to prevent damage to the meter if the input limits are exceeded. Check the fuses if the meter displays a reading of 0.00 when testing DC Volts output.

Refer to the Fluke® Operator’s Manual for this procedure. Replacement fuses #19449 for Series

IImeters or #19571 for Series III meters are available from your Briggs & Stratton source of supply.

The UNI-T® Operator’s Manual lists the fuse replacement procedure and type of replacement fuses required.

DC Shunt

The Fluke® meter will withstand DC input of 10- 20 amps for up to 30 seconds.

The UNI-T® meter will withstand DC input of 10 amps for up to 10 seconds.

When checking DC output on 10 and 16 amp regulated systems, the DC Shunt #19468 (Figure 5) is required to avoid blowing a fuse in either of the meters.
