Testing Your Stator On or Off Your Bike

 

In this this video tutorial I demonstrate how to test your stator. This tutorial will work for most any sports bike, but with that said always check with your service manual first for the proper recommended output readings as well as test lead placement.

If you have a 04 / 05 Suzuki GSXR 750 like myself the service manual recommends putting your digital multimeter on the ohms setting and setting the dial indicator to the lowest possible setting. Additionally, when connecting your test leads to any two of the three wires, polarity doesn't matter. A properly functioning stator should see a range value within .02-.09 ohms on the DM according to the service manual.

After testing your stator be sure to inspect the copper windings for any sort of black discoloration. Discoloration on coil windings could indicate an issue with your charging system and it may be better to swap it out for a new one rather than finding yourself stranded on the road with a dead battery. One last tidbit of helpful information while you're in there, give all three allen head bolts a good torque down to insure none have come loose. Trust me when I say I speak from experience on this last part.
