Motor Coach Industries equipped with penntex alternators that, as installed, may collect moisture at the power stud.
The short version
MOTOR COACH INDUSTRIES, INC reported a problem with the electrical system alternator/generator/regulator. Here is what owners need to know.
THESE VEHICLES WERE EQUIPPED WITH PENNTEX ALTERNATORS THAT, AS INSTALLED, MAY COLLECT MOISTURE AT THE POWER STUD. THIS MOISTURE MAY RESULT IN CORROSION BUILDUP AT AND AROUND THE POWER STUD BASE.
THIS CORROSION MAY CREATE A SHORT CIRCUIT BETWEEN THE POWER STUD AND THE ALTERNATOR BODY, WHICH IN TURN COULD RESULT IN BURNING OF THE POWER STUD OR THE POWER CABLE END. THIS COULD INCREASE THE RISK OF A FIRE.
MCI WILL INSPECT AND MODIFY THE ALTERNATOR INSTALLATION FREE OF CHARGE.
