Rareelectrical New 5/8" 1-Wire Alternator Pulley – Fits Delco GM 10SI, 63 Amp, Agricultural & Industrial Use

This is a brand new Rareelectrical alternator, and it's a solid choice if you're working on a Delco GM 10SI setup.

It’s a one-wire design, which makes installation a breeze—especially for agricultural or industrial rigs.

It cranks out 63 amps at 12 volts and spins clockwise.

The pulley is 5/8-inch with a single groove and an external fan to keep things cool.

All the regulation is internal, so no extra box to mount.

Just a heads-up, California residents: this thing has a Prop 65 warning for stuff like Lead and Silica.

It’s made in China and weighs in at just over 12 pounds.

Part numbers 683058070104 and 7127-3 cross-reference to this one.
