Just curious, what were the circumstances? Climbing a hill? Heavy
acceleration? or just putting along.
thanks, Mark

Subject: [ElectricMotorcycles] Another Alltrax let's the smoke out
Well for the second time my Alltrax controller let the smoke out. It
should still be under warranty so I will be getting ahold of Alltrax
again, but I wonder why it did it. I never have gotten around to putting
in my main contactor so I know it is not voltage spikes. I just use one
of those switches with a the big red plastic key. My precharge circuit
consists of a momentary switch and a 6 ohm resistor that I engage until
the green LED comes on. The only other thing that I can think of is that
I am running a 54 volt nominal pack on a 48 volt controller, but
everything stays within the controllers rated values. The controller is
disconnected during charging as the pack can go as high as 75 volts, and a
fully charged pack usually settles down to around 58 or 59 volts. The
controller has built in overvoltage protection which kicks in at 60 volts.
Has anyone else had let the smoke out of their Alltrax with a series wound
motor?
I'll talk to Alltrax before I decide anything for sure, but I'm
considering liquidation at this point. the motorcycle has been a lot of
fun, but it has a way of always spending more of my time and/or money :-)
