Need help with my throttle!?!?

[ekline309]

Hey guys,

I'm having some problems getting my Hall-Effect throttle to control my brushed DC motor. Both the throttle and controller were ordered from here: http://www.electricscooterparts.com/throttles.html.

The controller has 3 input wires colored red, black, and blue.

The throttle has 4 outputs colored red, yellow, green, and blue.

Currently I have the controller hooked up to my motor, battery, and on/off switch. With the switch on, I insert the throttle tabs into the controller and with one configuration the motor spins slow, another it spins medium, and with the opposite of slow, it spins fast. Regardless of configuration twisting the throttle does nothing to change speed.

You could call this speed control, but rolling down the street swapping throttle wires is not my idea of a smooth ride.

Any ideas??

how about filling in a couple more blanks like for instance which controler?

add to that which combination produces what effect?

have you tried emailing tech support at Scooter parts?

The controller is the 24 Volt 500 Watt unit from the same vendor.

Here are the effects:



Emailed tech support and here is their reply:

Hello,
Not sure what the problem is. You do need a switch wired in for the controller to operate.

Your controller has three wires. I think they are:

Red = 5V (approx) output to power hall sensor in throttle.
Black = Ground (0V) reference.
Blue = 0-5V input. 0V = motor off, 5V = full speed, intermediate voltages
result in in-between speeds.

Your throttle has four wires. I think they are:

Red = 5V input to power hall sensor.
Yellow = Ground reference.
Green = throttle output signal. Should vary between 0-5 V or 1-4 V or similar.
Blue = LED battery gauge input signal. Not used with your controller.

So, you should hook:

controller throttle
------------ ----------
red red
black yellow
blue green

Give it a try anyway. It would be much easier to confirm with a DMM (Digital Multi Meter).
A test you can do is to secure the bike off the ground, then short the red and blue wires from
the controller together (no throttle connected). This should run the motor at full speed.
Another thing you can do to test the controller independent of the throttle is to hook a 1K Ohm
potentiometer to the controller. Red and black to the outside terminals, blue to the center (wiper)
terminal. This should allow you to vary the motor speed from 0-100%.
