When setting up an older, unmarked stepper motor, the main challenge is figuring out which wires belong to each coil—especially if you don't have documentation. Maybe you bought the stepper motor years ago, or it was from a mysterious batch of parts with zero identifying labels. Either way, you're now faced with a wiring puzzle.

Here’s How to Determine Which Wires Go Together:
The Practical Options
- Continuity Check: Use a multimeter to test for continuity between two wires. If there's continuity, you've found a pair of wires that belong to the same coil.
- Friction Test: Connect a pair of wires together and try rotating the stepper motor’s shaft. If the resistance is noticeably higher, you’ve identified a coil pair.
The Fun Option
We recently learned an unconventional (and slightly more fun) approach from Steve, one of our technical editors. He shared a trick that might just make this process a bit more entertaining.Got any other methods that work for you? Share them below and let’s keep learning from each other!
