WISCONSIN MODEL VG4D - Wisconsin Motors

Problem: Low/No Charge
Possible Cause & Remedy
Test 4.0 With engine stopped,
unplug all connectors
between modules and
stator. Start engine
and run at 2400 RPM.
With AC voltmeter
check voltage
between each of the
black stator leads and
ground.
4.1 If one of the two 4.1 The stator is defective
voltages is zero or and should be replaced.
they are over 10% Static check stator per

Tests 7.0, 7.1, 7.2.
The DF 83 Analyzer was developed for testing the solid
state ignition and flywheel alternator components as furnished
on Wisconsin engines. It is very efficiently and
economically powered by four transistor radio type 9 volt
batteries. The DF 81 Flashlite Tester is used primarily for
checking continuity.

Test 5.0 REGULATOR GROUND
The YJ60 Regulator module must 1~ mounted to a metal
surface for grounding purposes. Check for continuity with
a VOM (R x 1 scale) or test light.
