My controller died. When I opened the case it was full of sediment dirt. I don't ride in rain, only ride through puddles if I cannot avoid it. I found one wire completely corroded away. My attempt to re-solder a new wire failed. There simply is not enough space to work on the circuit board. I also noted that there was no seal on the box-it was simply metal on metal which is waterproof at all. Also, the grommets sealing the wires on both end were not sealed. I email the pictures to the manufacturer and they ordered a new controller (no questions asked) even though my bike was 6 months out of warranty. When the new controller arrives, I will definitely check if it is sealed better. If not, I will improvise some rubber seal and silicone caulk. Unfortunately the controller is on back order from China for the past month and I have no idea when I will get it. In the mean time I am back to my regular bike.I used to love riding my bike in the rain on hot summer days...you know...those steamy days when you can actually smell the street. We have had several of those type days recently here in southern New England - with more on the way - and even though my Aventon Level is designed and certified to the IPX4 water-resistance standard, I just know too much about electronics, wiring, and micro connectors to feel comfortable doing so. Heck, after taking a long ride on some of our more humid days, I set my garage dehumidifier to its lowest setting (35%) in order to dry everything out for several hours. Direct water exposure however, is something that I just don't feel comfortable with.
The big issue with moisture exposure is that typically, problems don't rear their ugly heads - so to speak - until well after the initial and subsequent exposures, and then all of a sudden, something fails because of a small amount of corrosion, and one is suddenly reminded of the fact that electrical issues can be some of the most difficult issues to troubleshoot and repair.
On the other hand, maybe all I have to do is put a little Ziploc snack-bag over my monitor and just ride. Am I thinking about this too much?
