New to the forum and glad to find it. I bought my 168 from EVTA in 2005 and have about 1000 miles on it. Last September I pulled out of my driveway on a hot Texas day, got about 10 yards, and the bike quit on me. When I turn on the ignition it makes a high-pitched whining noise similar to the startup beeps, then the low battery (red) LED flashes, and that's it. I checked the batteries and all have 12V, the stack registers 48V. I'm new at this, but a pretty handy guy. Can anyone think of what I can try?
Oh, and I think EVTA is out of business, at least as far as the 168 is concerned. No one there will return my messages, and when I contacted the factory in Taiwan they sent me to Bravo.
