How to Install/Replace the Controller on your KeplerUpdated 5 months ago

Kepler Controller Removal/Installation Instructions

Install time: 30 minutes

Hardware and Tools Needed: 

• New controller 

• 3mm Hex Key 

• Flat Head Screwdriver

• Needle Nose Pliers

If you have received a new controller, you will want to test the new controller prior to making the final installation. To do so, follow the instructions below. 

Step 1: Start by removing the battery with the bike powered off. 

Step 2: Power cycle the bike by holding the power button down. This will drain any remaining voltage from within the system. 

Step 3: Clip all Zip Ties.

Step 4: Remove Controller mount bolts (X6) with a 3mm Allen wrench. 

Step 5: Disconnect the Controller to Motor Connection. You will need to unscrew the metal ring on the cable connector before removing the controller. This is located on the left side of the swing arm near the kickstand.

Step 6: Remove the rubber grommet from the frame. Use Pliers and/or flat head screwdriver.

Step 7: Remove Battery Tray bolts (X2) with a 3mm Allen wrench and disconnect the yellow power connection. Doing so will provide better visibility and maneuverability of connections within the frame of the bike. 

Step 8: Pull out the main cable harness and disconnect the remaining connectors.

Step 9: Disconnect all connectors from the malfunctioned controller and simply plug in all the connectors to the new controller and power the bike up with the display and keypad currently installed. If the replacement has shown to function properly, proceed by installing the new controller onto your Kepler. If it does not, contact Ariel Rider Tech Support at [email protected]

Step 10: Pull out the main cable assembly connector (black 10-pin Julet) and turn signal/headlight switch connector (4-pin HIGO blue) from the frame.

To replace or reinstall, repeat these steps in the opposite order.
