I have throttle with 3 position switch
gashandle.png

These 3 position switch works different than grin technologies

blue share wire
white cable high gear
brown low gear

Can I use these 3 position switch :?:
How to connect?

From section "5.6 Auxiliary Pot" of the [strike]Un[/strike]official Users Guide (page 38):

Unfortunately, your wire color description does not match the posted "7-wire" photo...
So - two answers:


  1. By the photo: from the throttle "3-Gears Public Wire":
    • red -> CA-5V
    • grn -> CA-POT
    • blk -> CA-Gnd
  2. By your description:
    • wht -> CA-5V
    • blu -> CA-POT
    • brn -> CA-Gnd

You can place the resistors anywhere convenient: Directly across the connector, in-line in the throttle wiring, inside the CA case across the cable pads on PCB, inside the throttle housing, etc.
 
Red, green, black are the wires for the throttle

White, blue, brown are for the 3 pos switch

Red and white >= CA +5v
Green and blue => ca line
Brown and black >= ca gnd

Red+white resistor green+blue
Green+blue resistor brown+black

Correct? :?:

[strike]Red+white resistor green+blue[/strike] ???

I don't understand the references to resistors and the throttle connections... The other stuff looks ok.

Here's how to hook up the 3-pos switch using the colors you report:

I bought a generic 3 position switch on AliExpress only to find that it wouldn’t work with CA3. Bought a $7 selection of resistors online, cut the wire, then spliced it all together as per the drawing in Appendix G, section 2, custom DIY 3 position switch. Works perfectly with CA3, plug and play. Fiddly soldering, but worth it!
 
Is not working :oops:

red (throttle) + white (high gear) Ca +5V
resistor 10K
green (throttle line) + blue (share wire) Ca pot
resistor 4.7K
brown (low gear)
resistor 4.7K
black (throttle Gnd) Ca Gnd

What is wrong? :?:
 
You sure that you have no shorts in your resistor wiring? Mine didn’t work first time - that’s how I learnt that heat shrink tubing exerts a lot of force on the wires and had managed to push a soldered joint through the insulating tape so that it shorted out on the next wire.

Did you test your circuit by plugging into CA3 or measuring the output voltages before wrapping it up?
 
Appendix G2 gives the interpin resistances to check before you “wrap” your circuit. Did they check out ok?
 
I have connect everything to the throttle connector, three pole switch and throttle
that was wrong I think
now I have connect 3 pole switch to CA aux
and throttle to throttle
it work but I can see no other power change, when switch to low/high gear
but this is maybe because the bike stands free
I have measure the voltage of the aux pot and this is not what in appendix G2
Low 0v in the manual stay 1.6v
mid 2.5v in the manual 2.42v
high 3.3v in the manual 4.99v
Is there something wrong?

I measure the resistance 3 pol switch its like in the manual
I do not understand what I need to change in the CA setup
aux setup 3 pol switch that is what I changed
 
I have tried with the orginal 3 pos switch
I get the same result
I think the config is wrong in the ca3
I'm study the manual, and changed the config
not good I think :oops:
can you give me what I have to change in config for aux 3 pos switch
 
Well if the test voltages don’t come close to matching what is listed as the required outputs for that circuit then something isn’t right.

In CA3, set up Aux Analog, 3 pos switch, power lim (that’s what I chose to use, other options available). By default high is 99% at 4.99 V, I.e. 99% motor power output. I put medium at 25% (around 30 mph) and low at 8% (around 20 mph).

Once I’d got the circuit with the resistors right, the set up was very easy, sorry that you’re still having a hard time with this.
 
the problem is not gone
Pos 1 1.60V 31% PWR (good)
View attachment 7

Pos 2 2.42V 31% PWR (not good!)
the first fault, pos two, that must be 66% :warn:

Pos 3 4.98V 99% PWR (good)

I gave set to 3 pos switch, and I get only two setups!

NO SETUP FOR HIGH
When I switch to low or med I get no change, it give
20181115_085116 (Groot).jpg
1119 Watt
20181115_084944 (Groot).jpg
3500 Watt
Pos switch 1 and 2 give 1119watt
Pos switch change to 3500 watt
:?:
 
I have also 2 button aux digital switch.
When I switch this on, I get only 2 pos switch on 3 pos switch!

When I switch aux dig off it works! :confused:

What is wrong?
 
the dig aux switch is better, so I shall remove these :lol:
