+Usually the older models have single/mainboards.
+You can ask the seller to open the hoverboard and send you a pictures, but he will most probably accept only if the hoverboard is defective.
+Ask him what's the chip model/brand to verify if it's [compatible](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Firmware-Compatibility#mainboard) with this firmware. + +### The hoverboard turns ON +Press the sensors on one side, tilt the hoverboard in each direction to check if the motors runs smoothly.
+If it's not working, the sideboard is probably defective.
+If the hoverboard turns OFF, the battery has probably lost too much capacity and is not able to deliver enough current.
+ +### The hoverboard doesn't turn ON +Most of the time the battery is defective.
+If the charger is still available, try to turn the hoverboard on while it's plugged, this will prove the controller is still working.
+ +### Motors +Make the wheels spin manually: +* if you feel wheels are cogging, 2 mosfets of the same phase are probably shorted, you will have to replace it. The gate drivers could also be damaged +* if the wheels are not spinning at all, it was exposed to water/humidity, you can through it away + + + + +
