ANSWERED Sondors X Fat tire not working after replacing LCD/Controller

Recommended Posts

Hi,

I purchased a new color LCD/25A controller for my Sondors X but it had no throttle function as I inadvertently purchased a single speed unit. I returned this to Sondors and re-installed the old original unit. It now does not work. My LCD comes live, I can change the pedal assist level but the motor is not working at all.  The motor is not providing  any assistance when I pedal or when I use the throttle. The battery is fully charged and there are no error codes displayed. I have checked all the electrical connections.

Can someone please guide me with basic trouble shooting. Thanks for your help.

Update, it has now thrown an error code No.22, Throttle Abnormality. Could the wrong controller have fried the throttle in some way?

Found the problem. A pin on the throttle connector was bent over. I was unable to straighten it, so need a new throttle. Is this the correct replacement for the Sondors X?

The Bafang 500W motor has the following written on it:

No, that throttle is for a Bafang  Mid Drive BBS 01/02/03 . Your Bafang 8Fun is a Geared Rear Dirve Hub motor. How many pins inside your Higo Throttle connector?

That newer model throttle has not been supported by any known regular aftermarket Sellers. There must be some Aliexpress supplier, Pasion eBike, is one of our Sondors, has the 3 conductor replacment but it does not have the correct Higo connector.  Since the pins in yours are damaged you can’t just splice in the Higo. You can Hard Wire it,  eliminating the connectors.

The Direct Replacment is avalable from Sondors.
