Our external alternator modified to SI-Series converts an original GM externally regulated alternator to internal "SI" alternator.
The fitted resistor is for use with or without a light bulb in the battery warning light circuit.
This is a plug-in conversion that can be used with 1985 and earlier "SI" series alternators.
