What's goin on!?!?

[Beyizzer]

Hey!!! I'm pretty new to ebikes, just kinda bought a convert-to-ebike kit on a whim, and weeks later figured out a way to buy a battery. bike worked fine for a week with minor complications but now the bike suddenly stopped working and even in a big city i guess no one wants to help fix it for money, so i've dived into something that is completely do-every-single-little-thing-completely-by-yourself. For anything else like that, forums are always my go to, and once i got stuff figured out i'll help everyone else along as well.

You may want to provide more details.

• Motor model
• Battery model/specs
• Controller Model

What do you mean by stopped:

• Controller display does not turn on
• Controller turns on but bike does not go at all
• Battery does not charge

What have you tried so far.

• Can you measure the battery output and see if it matches the specs when charged
• Have you checked all connectors to see if one may be loose or broken.
• etc...

Do you have a voltmeter?

Measure the voltage at the battery terminals. If the voltage is zero you probably have a bad battery.

Measure the voltage at the connection to the motor. If the voltage is the same as that measured at the battery you have a bad motor. Otherwise you have a connection problem somewhere between the battery and the motor.

A fuse in the battery pack?
