48 Volts Revving!

The controller is not fried, its just that 12 volts is no longer enough to fire it up in the presence of 48 volts. I have an email to Alltrax asking WHY?

I have the Alltrax KEY ON position jumped to the solenoid, using 48 volts to turn on the controller when I hit the moto's "RUN" position. Problem is the preload resistor across the solenoid allows the controller to be on when the main power switch is on. A trickle passes through to the motor too when the throttle is set, I am not sure this is going to work longer term. I will try the bigger preload resistor as prescribed in the Alltrax wiring diagrams, maybe that will quell the trickle.

BUT that said, the revving at 48 volts is really impressive - this thing is going to be a whole lot meaner on the street, should break 35mph.

In other news, Santa is getting me a "Kill A Watt" to measure power consumption - I hope to have this in line with the chargers to indicate how muchs its costing to charge up, and to determine how efficiently I am charging (or not). Actually, I need a DC version of the Kill A Watt to measure fuel level (this is what I am building with the iPAQ).
