Coyote Connect Fault - Turning Off

[Mike_dor]

Hi, 2017 Coyote Connect bike powers off after a few meters use. The bike looses its drive and the Control screen powers of.
To turn it back on again you have to switch the battery off, then turn the control screen on (works every time). Worth mentioned when it looses power, pressing the battery indicator on the battery does not work until battery turned off and on.
When working all 3 speeds work at correct speed.
24v battery showing full charge on screen and measured as 28v on multimeter.
If I disconnect the motor the screen will still turn off after a short ride (few meters).

Any ideas what I can check for next?

Thanks for any advice

That happens when the battery is knackered or not charged. You seem to have eliminated not charged.

Ah never, what's the best way for me to confirm if its the battery.
Do you think its strange how it still powers off the screen with the motor disconnected?
Thanks

To me, that says it all. You're measuring surface voltage which collapses as soon as you load the battery. The screen on it's own uses a paltry amount of energy - the motor needs a good chunk.

You could rig up 3 x 12v light-bulbs in series and attach to the battery and see if they stay on for more than a few minutes.

Makes sense but with the motor disconnected at the plug on the front wheel the screen still powers off after a few meters (distance varies).

Fotgot about this post... Thanks to everyone that replied..
Update - Traced fault back to 3 broken plates that joins the battery cells together. Making connection to get a voltage reading during testing but any vibration would stop the connection.
New battery plates soldered in and all working thanks
