New user/ aquired a drift trike

[JDunno]

Hello, name is JDunno. I've just registered here because I'm completely lost when it comes to electric bikes and trikes. I'm an old school combustion engine guy, trying to get up to par with the electric side of things. I've acquired a drift trike that has the golden motor on the front big wheel with a 48v battery that locks in place on the back. Upon getting juice in the battery and turning it on, I got no response from twisting the throttle. So I got ro checking things out and come to find the front wheel motor is or was completely full of water. That's where I'm at with it now. Was wondering if it's salvagable or do I need to replace it?
   Thanks in advance for my confirmation as a memeber and for any responses I may recieve.

Hi andto the forum.

Did the three LEDs on the throttle all light up when the battery was connected and turned On? If the LEDs were not lit up, it could be a battery problem.

If the motor has been completely submerged in water, the motor's controller and bearings may have been affected by short circuits or corrosion, especially if it was salt water.
However, if the wheel still rotates easily by hand, the stator and magnets may still be salvageable, but the motor would need to be dismantled to see the full extent of any water damage to the magnets, the laminated steel stator assembly and possibly the steel legs on the Hall Sensors.

If the entire trike has been under water, there's also the possibility that the water might have affected the throttle and/or the various connectors on the wiring harnesses as well.

Start by carefully checking all the connector pins for signs of water residue or corrosion, especially the 5 pin throttle connector and the main 10 pin connector between the main harness and the motor harness.
If you find any water residue, clean and dry the connectors thoroughly and see if it makes any difference.

Unfortunately, the controllers have been known to fail if water gets inside them, but you would have to remove the controller assembly to check for any signs of water being inside the controller. .
