E-scooter cuts out in rain?

[Big Tom]

I hope that this is the proper place for this question.

My dad has a Volt Canada e-scooter (60V - LifePo4) but has come upon some trouble if he gets caught in the rain. Yesterday a sudden storm caused the bike to shut down with no power to the motor (the cycle assist still was reading power). I assumed that it was moisture and loaded the bike into the truck and took it home. This morning, everything was working, so I guess it was moisture and dried out enough to work again.

My question is, how much AIR COOLING is required for the controllers on most bikes. The controller on this bike is very low on the frame and is open towards the ground (road mist and moisture). I was thinking about installing a shield in front of the controller to help protect and deflect moisture. But I do not know if this might cause over heating by possibly cutting off air flow over the controller.

On a second note .......... if anyone has suggestions as to what might be the cause (if it was not moisture) or a different solution, please feel free to add them here.

Thanks Tom

Cause was probably water in the throttle assembly or brake lever switches, combined with contaminants to short just enough voltage/current to cause non-operation. To quickly find out which one it is, you'd have to wet the bike down just like the rainstorm, and then disconnect the brake switch wires from the controller. If it then works, that's where the problem lies. If not, then it is probably in the throttle--dry out the throttle and see if it comes back, and if it still works after reconnecting the brake switches.

There are other ways to check, too, but that's the fastest/easiest, for me.

Thanks for the suggestions. I will, when I get the chance, check them to see if they are the problem.

Thanks again Tom
