TRANSPO 1-Wire Self-Exciting Voltage Regulator - Fits Delco 10SI, 12SI, 15SI, 17SI, 27SI Alternators (20 Pack)

Got a Delco alternator?

This is a bulk pack of 20 voltage regulators from TRANSPO.

They're designed for Delco 10SI, 12SI, 15SI, 17SI, and 27SI alternators.

These are 1-wire, self-exciting regulators, meaning they simplify your wiring.

The voltage set point is 14.8 volts, which is ideal for keeping your battery charged properly.

These particular ones are new old stock—they were removed from brand new alternators to make way for heavy-duty versions, so they're unused but may not come in the original box.

They cross to part numbers like 35-101-1 and 8040-6241.

If you're rebuilding alternators or need a batch for your shop, this 20-pack is a solid deal.

Reliable, simple, and ready to work.
