ELECTRICAL SYSTEMS
Equipment Used for Testing
NOTE: Not all testing equipment shown is used on every
engine model.
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.
Briggs & Stratton offers a clamp style multimeter (p/n 19602)
that does not require use of a DC shunt. A Digital Multimeter
can also be used but will require a DC shunt.
NOTICE 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.
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 is required to avoid blowing
a fuse in either of the meters.
22
Tachometer
Tachometer p/n 19200 (A) or p/n 19598 (B) are available
from your Briggs & Stratton source of supply.
23
Starter Motor Test Fixture
A starter motor test fixture may be made from 1/4” (6 mm)
steel stock.
1. Drill two 3/8” (10 mm) holes for starter mounting bracket
(B).
2. Using same spacing, drill an additional 3/8” (10 mm)
hole (A) for alternate starter mounting position.
3. Using a #7 bit, drill two holes for mounting Tachometer
#19200. Tap the holes for 1/4-20 NC screws (C).
24
Other Equipment
A growler or armature tester (checks armature for continuity,
shorts, and opens) is available from an Automobile
Diagnostic Service supplier.
Also, a known good 12 Volt battery is required when testing
starting systems or alternators.
Oil Gard System
Engine Will Not Start
1. Check engine oil level. If oil level is between ADD and
FULL, proceed to Step 2. If low, add oil until level is
between ADD and FULL mark on dipstick. If engine
starts and runs the problem is corrected.
