M365 data cable
The Data cable connects the motherboard in the base of the scooter to the display.
The cable is 1.2M long
One end is a 4 pin circuit board connecter and the other is a 4 pin Juliet cable
Other than seeing obvious visible damage to the cable it is very hard to tell if it is damaged or not as the parts it connects to may have failed.
If your battery is working fine, a new motherboard and display have been fitted and still no power to the display, then its time to see if this cable if the problem
How to fit the M365 data cable
You will need to undo the 4 screws holding the handlebar into the pole.
Remove the red rubber protectors on the pole and the base of the scooter.
Attach a long piece of string to the cable, this will make it easier late to fit the new one.
Flip the scooter so you can access the battery housing and remove the base plate.
Pull the old cable through remembering the string that is attached.
Unplug the old cable from the motherboard and attach the new cable.
Un-tie the piece of string and attach it to the end of the data cable that connects to the dashboard.
Carefully you can now pull the string through and it will pull the cable up through the frame of the scooter.
This is a bit of a fiddly job to do but it will look a lot better than having the whole cable hanging out the side of it.
Once its all back to where it should be and you have re-attached to the dashboard, screw the handlebars back on
Reattach the red rubber protectors into the handlebar pole.
Turn on the scooter and see if it works. If it does, only then move onto the next step.
Last but not least is attaching the battery housing base plate. remember to use locktight on the screws.
Take this opportunity to use a bathroom sealant to make sure no moisture can access the base of the scooter. Where the data cable enters the base of the scooter is actually the main area where moisture and water can enter.
This is a major design floor and you should use this opportunity to fill the gap with sealant thus fixing the flaw.
