JEGS 1-Wire Alternators:

One-wire alternators have a turn-on point (sometimes called "cut in"), typically about 1200 engine RPM. JEGS has developed rotor poles and stator stacks that carry a higher magnetism to provide an instant regulator "cut in" without engine acceleration. Our 1-wire alternators are manufactured with an exclusive low "cut in" of 880 engine RPM, which is much lower than any other alternator of its type. This is the speed at which the internal sense circuitry connects the battery to the voltage regulator and turns on the alternator. Once the voltage regulator engages, the alternator will stay on and charge until the engine stops completely.

FAQ

Does a 1 wire alternator need to be grounded?

• Yes, grounding is essential for optimal performance. Ensure a solid connection between the alternator case and the engine block to establish a proper ground for the GM 1-wire alternator, like the JEGS 10161.

Do I need a voltage regulator with a 1-wire alternator?

• No, a GM 1-wire alternator, such as the JEGS 10161, eliminates the need for an external voltage regulator. Its simplified design integrates the regulator internally for a straightforward installation process.

What gauge wire for one wire alternator?

• For a GM 1-wire alternator, like the JEGS 10161, a 4-gauge wire is recommended to ensure efficient power transfer. Adequate wiring promotes optimal charging performance for your vehicle.

What is the advantage of a one-wire alternator?

• The primary advantage is simplicity. JEGS GM 1-wire alternators streamline installation with a single-wire setup, reducing wiring complexity. This makes them an excellent choice for easy and efficient charging system upgrades.
