#### SUBJECT: Battery Telltale Light Flashes Intermittently at Start of Windshield Wiper Pulse (Install Suppressor Diode)

#### MODELS AFFECTED: 1991-1993 Saturns

CONDITION: While windshield wipers are on in the intermittent, mist or wash settings, the battery telltale light may flash quickly at the start of the wiper pulse.

CAUSE: A voltage transient from the windshield wiper module causes the voltage regulator on the generator to reset causing the battery telltale light to flash once each time the reset occurs.

CORRECTION: Install suppressor diode assembly into wire harness according to the following procedure.

#### NOTE: This condition does not cause a malfunction in the wiper or charging system.

#### NOTICE: If wires are incorrectly positioned in suppressor diode, the diode will cause a short circuit causing the 25A Wiper Fuse to open.
