Hi, Aliexpress is offering rectifiers pretty cheap. Some with cooling fins and some without. Anybody experience with these units? Good? Bad? Do or don't?
I was considering these for the FZR https://www.japbikespares.com/yamah...gulator-rectifier-assembly-15980#!prettyPhoto https://www.2fiftycc.com/index.php?threads/fzr250-add-ons-aftermarket.9799/#post-110573
I am in the wrecking business and I see plenty of customers with failed Chinese reg’s , while I am sure there are some decent ones out there, many are rubbish and cause more damage than good. One guy with a vfr400 has is battery swell in his battery box from over charging. It is such an important part of your Electrical system , I personally only buy / use name branded ones. I also find that many of the failed regs can be attributed to burnt and crispy wiring going to the reg , due to excessive heat cycles.
But i also used the Forsetti Chinese regulator on my uncles' Virago about 18 month's ago and it's still going good. The Forsetti reg/rect's are chinese Shindengen (Japan) copy's but apparently are higher quality than most. For a cheaper option i use decent quality original secondhand Shindengen reg / rect's one's on my bike's, my used R6 regulator off a low km's bike has performed faultlessly over the last 2 year's and it only cost me $20AU from the wrecker's
My first batch of around 400 Chinese regulators for the Hondas had about 2 or 3 defective units. The second batch of 400 had 2 or 3 that worked properly. I still have 311 of those with me, which I can't sell, because I know they will fail. Some smoke to catch fire as soon as you start the bike, others can last up to 2 weeks. But they will fail. Chinese electronic parts for motorbikes (regulators, solenoids, relays, etc) are not always badly made, but you can't really tell by looking at it. It's a risk you take. May work and you save heaps. May fail and you'll have to spend heaps. Go OEM. Cost more, but gives you peace of mind.
