Remy releases voltage control technical bulletin

Remy has introduced a technical service bulletin for techs titled “Remy GM Regulated Voltage Control (RVC) Computer-Controlled Charging.”

In it, the company writes, “GM RVC charging system voltage varies from approximately 11.5 to 15.5 volts. During fuel economy mode, when voltage is at the lowest, customers or technicians monitoring battery voltage may believe there is a charging system concern. Simply turning on all vehicle electrical items will cause a mode change and make the voltage rise.

“Conversely, when the system is in battery sulfation mode, voltage may rise as high as 15.5 volts for three to four minutes. When there is a legitimate failure in the system, the battery lamp will illuminate and/or diagnostic codes will be stored.”
