Single-Phase Voltage Regulator - $139

Electrosport or Rick's Electric brand voltage regulator model #ESR510. Less than 1/2 the price of the OEM regulator. Fits all single-phase alternators with 2 yellow wires (except for '98 ST2).

NOTE: Aftermarket regulators eliminate the OEM connectors, which are the weak link in the system. Solder or use marine-grade shrink crimp connectors.
