Hi Guys, I am new here, i want to buy a new Thumb Throttle.
I wanted to know, what is the signal wire means?
How can I know the exact cables i need to connect with out any glitch, is there any device that i can check with? or i need to check it from the controller? is the colors of the wires are reliable?
The signal wire is the wire that the throttle's output signal is carried through. Most electric scooter signal wires will output between 0.8 and 4.2 Volt depending on the position of the throttle.
On most three wire throttles the Red wire is for +5V DC input, the Black wire is for Ground/Negative, and the Green/Blue/White wire is for the Signal. Most throttle manufacturers follow these wiring standards however there may be one that does not which I am not aware of.
The output of the throttle connector on the controller can be tested as well as the signal output of the throttle. Here is a guide showing how to do that.
Please let us know if you have any questions.
