I'm building a bike and some of my parts are used, like the stator.

Visually, the stator looks ok. In other words, there are no signs that it has been burnt up like I've seen in pictures of bad stators.

However, I would really hate to get this used stator installed and then find out something is wrong with it. As you know, it's buried in the primary.

I'm not much of an electrical guy....is there a way to test this used stator before I install it? I'm wondering if I can hook it up to one of those electrical tester thingy's and get some kind of an idea if it's ok or not?

With this said, my bike does not yet have any wiring, battery, ECM, etc. Those are next on my purchase list.

Thanks,
D

 

Inspect it for obvious damage, burnt spots or knicked, broken wires. Use a good digital multimeter, and test between the three phases coming out, there should be a consistent , very low resistance (ohms setting) between all three leads. Then check from a lead to the metal body of the the stator, should be no continuity, very high resistance. That is the testing to be done while off the bike. Tests like this are easy to find, just google what you want to do. The manual for the bike, which you will need, or really want, to save yourself a lot of grief, will cover it in detail.

 

Cool. Thanks for the info!

 

Personally, I would never install a "Used" stater.

You can bench test the stator by measuring the Ohms but that's only half of the equation. A grounding test must also be performed while the stator is mounted and the electrical system connected. You might get lucky but why take the chance. Stators are relatively inexpensive.

I hear ya...however, I started building this bike from the frame up. I can't afford to buy all brand new parts....it would be cheaper just buying a bike all put together. In some cases I'm going to have to take a chance I guess. My transmission and clutch were used as well but I had them taken apart and looked at to ensure they were good. About the only things new on my bike are the motor, starter, rear wheel and axle, both tires, and many of the bolts that hold everything on. Everything else is used.

D,

Send me a mail at my personal address. I'll send you the procedures and specs to test a stator. Will need the Amp output of the stator or the year/model of the engine.

Will do!

FWIW, I tested the continuity tonight...it passed that test.

 

Just did this. Everything passed. Thanks!
