Stator
Yamaha Royal Star Midnight, Tour Deluxe and S 1300 - 1999 to 2013
This is a brand new aftermarket stator built as a direct replacement for the original charging coil fitted to the Yamaha Royal Star Midnight, Royal Star Tour Deluxe and Royal Star S 1300 from 1999 to 2013. It is a plug-and-play, direct fit part: the 18-pole core, the three-wire output and the single three-pin plug all match the original unit, so it drops into the original position and the loom connects straight up with no modification to the bike.
The stator is what generates the electricity on the machine. As the rotor spins around it, the windings produce alternating current, which the regulator rectifier then converts into the direct current that charges the battery and feeds the lights, ignition and accessories. On a heavy tourer that spends long periods at steady revs with a big electrical load, a tired stator is one of the most common causes of a flat battery. This replacement uses the highest grade of lamination material and the highest grade of copper winding, insulated to withstand 200 degrees Celsius, so it copes with the sustained heat inside the engine case. Connectors and the rubber grommet come already fitted, and the opposite connector for the main harness side is supplied as well, so both halves of the charging plug can be renewed together.

Frequently Asked Questions
Will it fit without modification?
Yes. The core dimensions, the three-wire output and the single three-pin plug all match the original stator, so it sits in the original mounting position and the loom plugs straight in. No cutting, splicing or drilling is needed. Disconnect the battery before removing the stator cover, and have the work done by a qualified technician if you are not comfortable working inside the engine case.
What is included in the box?
The stator assembly with its connectors and rubber grommet already fitted, plus the opposite connector for the main harness side. The stator cover gasket and mounting bolts are not supplied; the original hardware is re-used or replaced separately.
How do I know my old stator has failed?
The classic signs are a battery that will not stay charged, headlights that brighten and dim with engine speed, a charging warning light, or the machine dying and refusing to restart after a long ride. To confirm it, disconnect the stator plug and measure between the three white output wires - each pair should read roughly 0.6 ohms. Then measure from each wire to the engine case; that should read open line. A very low or very high reading between the wires, or any continuity to the case, means a shorted or burnt winding.
Should I replace the regulator rectifier at the same time?
Not automatically, but it is worth testing. A failed regulator rectifier can overload and destroy a healthy stator, and a stator that has already shorted can take the regulator with it. If the original stator burnt out, check the regulator and the charging plug before fitting this part, otherwise the same fault can repeat. The opposite connector supplied in the box lets you renew the harness side of the plug, which is the most common weak point.
