Hey guys just an update I did buy a replacement motor from electro bike world it's the exact befang motor replacement

I hooked it up turned it on and lo and behold I just have no battery bars on my area 13 bolt-on motor controller screen. So this leads me to believe that it's the battery??

What are you guys think thanks for all the help cheers!

Hey everyone new to this forum and looking for help.

I currently just bought a rad wagon 4 (April 2023). And just like Tim the toolman Taylor I had to upgrade it! So I bought the bolton/area 13   35 amp motor controller with screen. It worked great for a long time however the PAS wasn't working at all. so Area13  sent me a whole new motor controller with screen and everything I hooked it up and the PAS still didn't work. Then I hooked up all the original stock Rad stuff to take a video to show them that the pas does in fact work with the stock components.

When I hooked everything back up to the area 13 motor controller I got a weird warning on my screen it said?Motor position sensor fault? or ?Motor controller short circuit fault!?

It started to work all of a sudden so I loaded up for a ride and when I walked it to the street I had nothing.
Right now it actually  shows no battery bars on the area 13 screen but does show 52.3 volts beside it. There's no throttle response also it doesn't even show that I have pulled the throttle which it normally does on the area 13 screen. So I hooked back up the old Rad motor controller and screen and that one says full battery but it also gives me nothing when I turn the throttle.

So with all that information do you guys think that possibly the motor could be blown? I did read on forums that the 35 amp motor controller is too powerful for the stock b Fang 500/ 750 peak motor that comes on this bike. 

Later I read I should have had the C setting on a 5 for less wattage and it was set to C10 maybe that blew the motor or is it the battery?

Never had an issues before I started swapping the controllers and screens around.

I shouldn't have touched it!! Going to a cottage In 3 weeks HELP!!

How can I diagnose what's wrong and get it fixed in time
