Issues
Power Turns Off When Driving
Sometimes while driving the power turns off. Toggling the power switch fixes the issue and we can continue along.
Thoughts:
- Could be a loose connection that gets jiggled when hitting bumps.
Observations:
- Noticed that the ground connector at the base of the battery was not very tight. Compressed the connections to ensure that they connect better when attached to the bike.
- Performing capacity test to see if the battery is ok.
- Capacity test resulted with a battery capacity of 8.67Ah. Looks good.
