Greetings,

I?m trying to get my Radwagon 4 working with an upgraded 35a controller.  So far can?t get PAS working.  The red LED on tge sensor immediately comes on upon connection and stays on, I thought it would only be on (and blinking not constant) only if the pedals are actually moving.

Is this an incompatibility issue?

Thanks,

Tim

Greetings,

I bought the 35a controller from Electro Bike World. it appears to be the same unit sold on several sites and I basically followed the steps in this youtube video.   https://tinyurl.com/b6atmurk

Pretty straightforward, except the PAS sensor wasn't working, and when I went back to the stock controller, I had an error 30 as soon as I plugged in the PAS so that seemed to narrow it down.  I ordered another PAS sensor from RAD and connected the wire before installing it to verify the red light was on. It was. 

Since I don't have a crank puller and bottom bracket remover, I took it to my neighborhood bike shop for install.  They soon called me to say it was installed but the PAS feature wasn't working.  The red light no longer comes on.

Neither sensor works with the original stock RAD controller now either, so it would seem the 35a controller fried them both.  But this is weird as I can't imagine the volts/amps to the sensor are much.

I don't want to order a third PAS sensor w/o a better strategy. 

The company I bought the controller from states that sometimes the Rad PAS sensor doesn't work, but the one they sell will, but in the picture on their website it looks identical or close.

In the meantime, the bike still works in "throttle mode," but I never wanted to loaf completely, I just wanted some help on the hills when I have my two kids on board.

Info, thoughts, experiences?

Thanks in advance,

Tim
