It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up it will simply turn off for a while and cool off.

 Improved heat sink and charging capabilities

Before installing your new voltage regulator rectifier:
Check the AC output of the stator.
Replace any burned or corroded connectors on stator and regulator/rectifier
Check and repair any melted wiring.
Use hi-temp dielectric grease on all connectors.
