RMStator Series Regulator with SurePower ECM Bypass Harness

RMStator's Series voltage regulator brings better reliability and charging system performance. A Series regulator is a significant upgrade over typical shunt type voltage regulators.

A shunt regulator controls battery voltage by grounding the stator coils to dissipate current as heat, rather than sending it on to the battery. Series regulators control battery voltage by intermittently disconnecting stator coils from the regulator electronics, limiting current flow through the unit and on to the battery completely.

This results in lower regulator and stator temperatures, more accurate voltage regulation, and increased reliability of your charging system components.

• Runs much cooler than Shunt and MOSFET voltage regulator/rectifiers and way much cooler than OEM parts
• Machined billet aluminum casing dissipates heat 33% better than standard molded casing
• Power only flows through the electrical components when the battery is charging
• Allows the stator to have lower current flowing when not used, extending its lifetime

Improved Heavy Duty Bypass Harness

• Automotive grade wiring harness with OEM-quality heavy-duty connectors
• Made with the same connectors as OEM parts,
• Resists heat, oil, acid, gas and more with very low electrical resistance
• Includes the opposite connector (main harness side)
