About 3 months ago, I finally discovered that the proper tire pressure is 30 PSI. Rolling resistance is so much lower that I've reduced my motor usage by 75%. The controller runs cooler, and if there's moisture, circuitry may take longer to dry each morning. The first couple of miles is when the controller has sometimes failed to recognize a shift.
The bottom and sides are one piece, so there won't be a leak between them. The sides fit into slots in the lid, so that should be okay. The vulnerability must be at the ends. On the front, I saw that water could run through the rubber grommet on the cables. RTV fixed that. I saw that water had sat on top of the controller. I didn't know if the end plate gaskets were totally water proof along the top, but I added a little RTV.
The end gaskets don't fit tightly at the bottom. That was so crazy that I thought they were open for ventilation, and the designer knew that water couldn't flow up into the box. That seems to have been wrong.
With the grommet sealed around the cables and the end plates sealed on all four sides, I think my controller will be okay.
I appreciate these details, as well as all you've done to record your efforts with fenders etc. I see from your earlier threads that some of your negative experiences came when riding on wet surfaces after a rainfall. Have you been riding in the rain with that controller as well? Apologies if you've addressed this elsewhere and I missed it.
