Since I am having to mix and match items that are not in "kit" I'd like to simplistically test the controller without my full fledged battery. I've already fried the connectors of 1 controller twice. Scarey. I'd like to use a minor power source so a psu power source (maybe at 12 volt) to see is the controller is getting/ transmitting power. So It would show this via the throttle terminal . Is there any danger to the controller if I tried to do this? It seems like with so many Chinese controllers not having the on off switch that knowing of the unit is functional as is would save me some grief. So hooking up on the 12volt rail on psu amnd measuring throttle for power would seem to indicate the controller is good as is if Ido get a reading...if not then I need to connect one of these other unamed wires to a power source.
