I don't know if it's such a good idea to have the throttle control hooked up to the button..
Those throttles are known to be quite finicky in terms of weather (rain)..
I'd be curious to know if it's hooked up to the +5v, gnd or variable line.
(I know a few controllers make your motor go WOT if the Neg line is disconnected during movement...)
Let's hope, your button is not hooked up to the gnd line.
That's a really strange setup...
Does your controller have a "control line"? (it would be hooked up to a key switch.)
(Small thin red wire next to main positive).
On those throttles, I've ALWAYS hooked up that switch to the control line and the LED battery power line.
(They both are battery pack voltage but have no amp draw to worry about)
This way, when switch is "out" power to controller is "off" and so are the LEDs..
With switch "in" power to control line is supplied (controller on) and LEDs are lit.
P.S. It's also good if you don't have a key switch to begin with..
