Hello! Apologies if I put this in the wrong place.
Sometime ago, I got the Kato M2 starter set, which came with a throttle/powerpack (
http://www.1999.co.jp/eng/10040265). At first it was working great, with the throttle part working correctly.
However, recently, it's developed a problem where there are two speeds. "Fast" and "So fast the train violently derails on curves". The Fast speed applies when the throttle is at 0, all the way to the red bit. When you move the throttle into the red bit, you get the second speed.
Is there an easy way to fix this?
Yes: Send it off to Kato USA for repair! It sounds like a fairly major electronics issue, and not knowing anything about the internals, I'm guessing it's not going to be easy. Unless you know your way around a soldering iron and a 7812, in which case you might find the challenge interesting. Otherwise, I'd send it off for repair.
That sucks! :( Do you at least have a backup throttle you can use? (I'm guessing no?)
