Review on 🚗 Enhance Your Vehicle's Power with the Motorcraft GR540B New Alternator Regulator by Leroy Jacobs

Excellent product. Far superior to the original mechanical unit. Replaced all other charging system parts (battery, alternator, alternator harness, etc.) except this one. Should have started here. It went from 12.73 volts with the engine and headlights to 14.89. Amazing difference. No more dead battery! This device is available at select Mustang stores for more than double the price.
