Voltage Regulator Rectifier Bypass – BMW Assorted Models

The failure-prone harnesses on BMWs are known to develop corrosion, which increases electrical resistance. This, in turn, raises the temperature of wires to the point where connectors start melting. When this happens, the voltage regulator (and most likely the stator) fails, leading to steep repair expenses.

RMStator's new bypass voltage regulator brings back the renowned RMSTATOR Series technology, designed to bypass the main wiring harness and connect the voltage regulator directly to the battery. This configuration has demonstrated a major increase in voltage regulator reliability in real-life scenarios over the years.

Features:

• Series Technology: Significantly lowers regulator and stator temperatures for more accurate voltage regulation, increasing the reliability of your charging system components.
• PRO-FIT System: Includes everything required for an RMSTATOR-style professional installation: part connectors, bypass harness, and dielectric connector grease.
• Power only flows through the electrical components when the battery is charging.
• Allows the stator to have lower current flowing when not in use, extending its lifetime.
• The regulator is easier to mount because it is smaller than the OEM.
