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!
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?
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
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.
