ALTERNATOR “R” STATOR TERMINAL
CORROSION PROTECTION
The “R” stator terminal on alternators may become
corroded due to oxygen in the atmosphere combining
with the impurities on the surface of the exposed
conductor. This corrosion may interfere with the
alternator’s RPM signal, in turn adversely affecting the
performance of the EOS (electronic overspeed
switch).
To prevent the corrosion from occurring, a sealant
must be applied to the terminal to prevent oxygen in
the atmosphere from coming in contact with the
conductor.
There are two (2) main types of connections on the
“R” stator terminal:
1. A 3/8” female stud type connector and
2. A molded pin plug.
Dipit is recommended for use on the stud type and an
antioxidant grease is recommended fro the plug type
connection.
