09PG2 - Photon Gen 2: The display shut down during ride

Symptoms 1

The display turns on every few minutes or display cuts when using the throttle.

Reasons

• Auto Off function is on.
• Loose connections
• Uncharged or failed battery
• Failed display
• Failed controller

Checklist

1. Check that the auto-off function on the display is not turned on.
2. Unplug the display and the wiring harness and check the connectors at both the display-harness and the controller-harness points. 
   *The pins on the connectors need to be inspected carefully as any pins that are bent or have moved from their original position, can cause issues. CYC or an Authorised Reseller may ask you for evidence showing that your connector pins are still in good condition. 
3. Ensure there are no wires that are pinched in or bent flat that could be obstructing the signal or damaging the cables. 
   *It's best to check the system with the wiring harness and cables freely moving i.e. not tied onto your bike frame.
4. Ensure that your battery is fully charged and in good condition.
   *You can use a voltmeter or multimeter to check that your battery is not corrupted. 

Troubleshoot

If you have completed the above checklist, proved that your connector pins are in good condition, and you still cannot find a cause for the kit not turning on, confirm the following: 

1. If you have another CYC kit or have sufficient additional spare parts, swap out the display to see if the display works on the other system. You can also swap out the controller and wiring harness respectively. If you can locate the issue by swapping out components, then you can report your findings directly to CYC or an Authorised Reseller to organize a replacement (i.e. you do not need to continue troubleshooting). 
   *If you do not have any spare parts, continue to step 2 below.

Solution

1. Replace the display

With the B+ and Key-in pins connected, if you can connect to the Ride Control app and your throttle is outputting power when pressed down, then the display has failed and needs to be replaced. 

2. Replace the controller

With the B+ and Key-in pins connected, if you cannot connect to the Ride Control app and your throttle is not outputting any power when pressed down, then it is likely a controller issue. Replace the controller accordingly.
