The bike's display will not turn on but the battery appears to be working.

The 1-4 wire harness cable could have come loose. To correct this, disconnect and reconnect the 1-4 cable. Check to see if any pins are bent or if here is any corrosion build up. After reconnect, try to start up the display, and this will typically resolve the issue.

Another potential cause could be that the cable connector has come our for a number of reasons. We have seen cases in which a bike parked on a rack will get caught on another bike when pulled off the rack. This can pull the cable out just enough to cause a problem. After riding a short while, it can come lose and the bike will shut down.

A change in temperature or moisture can also cause a bit of pressure inside the connector and could push the part loose.

You should not need to tape the connection, but we recommend checking the cable periodically. Note that some force is needed to fully engage the connection.

We have designed in a way that it can be easily removed if needed. This allows repair/replacement of the cable without replacing the entire controller. This improves the overall serviceability of the bike.
