Hiya,

I am at the testing stage of the controller and i have a small issue with the throttle potientomer. I have got a poteniometer from a golf cart that seems to work fine. When i check the output of the PWM it only works in a small range of the potienimeter . Do i need to change the resistor in the logic board to make the range better?

Cheers Barry :D

Without having to dig into any previous threads you wrote, maybe you can share "What controller" you're using?

This is a general forum for all controllers, not a specific one, so new threads likely need some reference point.

sorry about that. I am making one of Damian's DC controllers. From his github site.

If you need any other info let me know.

Cheers Barry

That's good info.

What is the resistance value of the potentiometer you're using?

Does it match the value required by Damian's controller?

i.e. is it a 10k throttle, but the controller expects 5k?

How many wires go into damian's controller?

Was it a cheap chinese potbox? I had one that was wired really weird and did not work.

Hiya,

It asks for a three wire pot. I have a 5 k one from a golf cart and i have a 100k from a mobility scooter. I will try and find out what size the controller is set up for .

Thanks Barry

Hiya,

Think i have the answer, should be a hall effect pedal and not a throttle pot. Will get one and see what happens.

Cheers Barry

Hey, nice. Looks like my LTC circuit design.

Succes story number 2. And I haven't even started my build yet.


Yeah, it's all hardware, so you have to tweak part values to get it to work properly.
