Design and connections correspond to original 74519-88, ready for installation.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe regulator converts the alternating current (AC) from the alternator into the 12-volt direct current (DC) used in the electrical system and keeps it within the defined tolerance range. This ensures the battery charges reliably and prevents light bulbs from burning out.\u003c\/p\u003e\n\u003cp\u003eConstruction and performance correspond to the original 74519-88, and the connections match the factory layout.
