Moturo Voltage Regulator Rectifier for Suzuki GN 125 AN 150 GZ 125 250

Moturo Voltage Regulator Rectifier for Suzuki GN 125, AN 150, GZ 125 and GZ 250

The Moturo voltage regulator rectifier for Suzuki GN 125, AN 150, GZ 125 and GZ 250 (model years 94-05) — due to its age, one of the most common components to replace in the electrical system. Design and performance are identical to the original; ready for installation.

The regulator converts the AC voltage from the alternator into 12V DC voltage, charges the battery, and protects components such as light bulbs from overvoltage. The voltage remains within the specified tolerance range, ensuring a stable electrical system.

Suitable for Suzuki GN 125 (model years 1994 to 1999), AN 150, as well as GZ 125 and GZ 250 (model years 1998 to 2005). Pin assignment and connector shape comply with the original Suzuki factory specifications.

Replacement takes about half an hour with a socket wrench set and a multimeter for functional testing.

Frequently asked questions

Does this regulator also fit the GZ 250?
Yes, it has the same electrical design as the GZ 125. Compare the pin assignment with the product image before ordering.

Do I need a TÜV registration?
No. Original spare part design, no ABE or registration required.

How do I check if my old regulator is defective?
Measure the voltage at the battery using a multimeter. With the engine running, it should read between 13.5 and 14.5 V. Values significantly lower or higher indicate a defective regulator.
