Voltage Regulator Rectifier for Suzuki LT and LTF Quads and DR Singles
Suzuki LT / LTF 160 and 250 Quadrunner, LTF 300 KingQuad, DR 200 S, DRZ 250 - 1987-2019 - RMSTATOR part RM30301
This is a brand new voltage regulator rectifier for the Suzuki utility quad and single-cylinder trail range. The regulator rectifier takes the alternating current the stator generates, turns it into direct current, and holds the charging voltage steady so the battery and the ignition electronics see a controlled supply. On these machines it lives a hard life under vibration and heat, and it is one of the first charging system components to give up.
The unit is a direct replacement for your original part - plug-and-play, direct fit, easy installation, with no assembly required. It is built with a higher grade of electrical components than the original equipment and uses an improved heat sink for better charging capability. It carries a single five-pin plug on a 250 mm lead and mounts on the standard 60 mm hole spacing.

Frequently Asked Questions
Do I need to modify anything to fit it?
No. It is a direct fit, plug-and-play replacement for the original unit on the listed models, with no assembly and no cutting or splicing required. The mounting holes sit 60 mm apart centre to centre.
What is included?
You receive the voltage regulator rectifier itself, with its five wires terminating in a single five-pin plug on a 250 mm lead. Every unit is tested before it leaves the supplier.
How do I tell whether my old regulator rectifier has failed?
Run the engine and measure across the battery terminals. A working system on this part regulates to roughly 14.5 V. If the reading never rises above resting battery voltage, or if it climbs past 15 V and the battery gets hot and gasses, the regulator rectifier is the likely cause.
My machine covers several of the listed models - how do I be certain?
This part covers a wide span of Suzuki quads and trail singles, so the safest check is the number stamped on the unit you are removing. If it reads 32800-19B00, 32800-19B10, 32800-19B11, 32800-13E10 or 32800-13E11, this is the correct replacement.
