RANSOTO Voltage Regulator Rectifier for Polaris Ranger & RZR 2013–2016 — Direct-Fit 14.5V Charging Stabilizer

RANSOTO Voltage Regulator Rectifier is a direct-fit replacement that stabilizes charging output for select 2013–2016 Polaris Ranger and RZR models.

If your Polaris is showing electrical flicker, a weak battery after riding, or inconsistent charging, a failing regulator/rectifier is often the culprit. This RANSOTO unit restores a steady DC output (14.5V ±0.5V) and is built from durable components to match OE fitment. It replaces multiple factory part numbers so it’s an easy swap for technicians and DIY riders alike.

How will this part affect my Polaris’s electrical system?

Installed correctly, the regulator/rectifier converts alternator AC to stable DC and governs voltage to protect the battery and electronics. A healthy unit prevents overcharging and reduces electrical noise that can impact lights and gauges. Use it to return charging performance to manufacturer specifications.

• Nominal output: DC 14.5V ±0.5V for consistent charging.
• Direct replacement for multiple OEM numbers to ensure correct fit.
