nals.
STANDARD: 0.1
Check for continuity between all three Yellow termi
nals and ground.
There should be no continuity.
If readings are far beyond the standard, or if any
wire has continuity to ground, replace the alternator
stator (page 10-5).
REGULATOR/RECTIFIER
SYSTEM INSPECTION
Disconnect the regulator/rectifier 2P (Black) and
alternator 3P (Black) connectors (page 17-9).
Check connectors for loose contact or corroded ter
minals.
If the regulated voltage reading (page 17-7) is out of
the specification, measure the voltage between con
nector terminals (wire harness side) as follows:

If all components of the charging system are normal
and !here are no loose connections at the regulator/
rectifier connectors, replace the regulator/rectifier
unit.
