Battery Fuse Check Guide

If you have been instructed by Rad Power Bikes Product Support to complete a battery fuse check, this guide will show you how to check a fuse. 

This procedure applies to the batteries used with 2018 and newer models only.  

Tools Needed:

  • Small flat head screwdriver
  • Small needle nose pliers
  • A replacement fuse

If the battery is not charging: follow the instructions in the Check the 5A Fuse section.

If the bike does not turn on: follow the instructions in the Check the 40A Fuse section.

Check the 5A Fuse
  1. Remove the battery. Set the battery upside down on a solid surface, with the battery in the "OFF, Unlocked" position.

    Caution.png Do not touch the "+" and "-" terminal contacts on the bottom of the battery, be careful to keep the exposed connector terminals clear of debris, and do not drop or damage the battery. In the case of damage to the terminals or battery mounts, please discontinue use and contact Rad Power Bikes Product Support immediately. Never open the battery housing, which will void the warranty and can result in damage to the battery, property, serious injury, and/or death.
  2. Locate the 5A fuse cover.
