I was annoyed a few days ago that both my Lezyne rear lights packed up at the same time. Having had issues with poor build quality and parts choices on Lezyne stuff in the past I had put them to one side for a closer look. Neither would charge.
The Zecto drive was about 2 years and 2 months old and the stripdrive about 3. Lezyne's website said for warranty lengths in UK ask your retailer.
Tredz very curtly and slightly rudely said "on yer bike". So I didn't order a replacement from them.
Took the strip drive to bits, or rather just pulled the gubbins out, the fault appears to be an IC chip that when plugged into the charger just gets stupidly hot. Googling the numbers on the chip gives no suggestion of what it does but I'll hazard a guess it's the charge controller. So tossed that aside as I doubt I'd be able to physically replace the chip anyway.
Took the Zecto drive apart. As soon as I had the PCB out it worked as it should. Fiddling around showed the fault was with the micro usb connector. I remembered I had some of them from when I replaced on in a phone years ago so dug them out. Managed to free the old connector from the PCB but my soldering iron was far to big to reattach. Tried a bit of copper wire in the iron which failed but then hit on using a sewing needle from the missus seeing kit. Bingo.
When I came to reassemble it I noticed that two of the holes in the red plastic lens which form part of the front were broken. Managed to get them back together with araldite and then strengthen them. Left it to cure before I reassemble.
For a brand that sings about their design quality I'm unimpressed with lots of aspects. The fact the thing is held together by 1mm or so of brittle lens plastic on the vulnerable corners. The really poor seal and ingress protection on both the Zecto drive and the stripdrive. I can't help wondering if they've both suffered ingress which has caused the problem. Newer stripdrives have a different charging arrangement, but are still poor. If I bought it again tomorrow I think I'd seal it up with Epoxy.
The bike desperately needs a new crank, chain and cassette. Being deep in mingy salty weather I'm loathed to change it. It all needs doing so it's not like anything is lost by leaving it. But the drive chain does go really rusty really quickly. Leaves me pondering if old really worn chains rust faster.
Anyway washed it clean and relubed.
