1-Wire Alternator Charge Indicator Light

One-wire alternators are a popular charging option for street rod and restomod builds. Unfortunately, the convenience that comes with this type of charging system presents a challenge for many users.

Since a single wire alternator no longer requires the exciter (IE the brown wire supplied in our Classic Update and universal kits) feed responsible turning off an in-dash charge indicator light, many users find out their quick and easy alternator swap has removed some of the functionality from their car.

It also means they have a red light staring them in the face any time they go for a drive. One solution to this is to simply remove the charge warning light from the gauge cluster. The more practical option is to install our 11 volt sensor module to keep the otherwise ever-present light at bay.

The module requires a simple, 4 wire connection and allows one-wire users to retain a charge warning light by monitoring total system voltage. If the module sees a reading of less than 11 volts, it will illuminate a warning lamp of your choice.
