Troubleshooting - 12v Relay Module
Locate the 12v relay pack. It is the small black plastic box zip-tied to the side of the motor controller (about the size of a deck of cards with wires coming out of it).
Open the Relay Pack
The cover snaps on/off the box, but a zip-tie ensures the cover stays on the box when subjected to vibration while riding. With a pair of wire cutters, carefully cut the zip-tie securing the plastic cover on the box. The plastic box is mounted to the motor controller with double-stick tape, so it should stay in place.
- Cut zip-tie & remove plastic box cover.
