I honestly don't know where to go from here

So I bought this akez king kong over the summer 2nd hand with about 400 miles and it worked great for about 4 months where I managed to put about 700 more miles on it the only exception being that the lights did not work which I didn't really care about as I was riding mostly during the day. One day I tried to connect the lights and that's when all the issues started. As soon as I tried to connect them I was met with an E06 and E07 error that would seemingly randomly swap sometimes even changing to E10. I bought a new controller thinking it might be a controller issue straight from akez. I connected the new controller and the same issues occurred. I then thought it might be the motor or a sensor in the motor and I connected it to a spare motor I had which i know works just fine and it had the same issue. I then ordered the screen thinking that might be the issue and now the screen won't even show anything. Any advice would be greatly appreciated as I dont know where to go from here and I really need this bike to commute to and from university.

You can google the model number of that screen and you should be able to find an instruction book for what the error codes mean.

I know this is dumb, but did you disconnect the lights with the new controller?
pablosanchezzzzz@reddit (OP)
I have not tried that.
VelVeetaLasVegas@reddit
Reason I axe is if the harness wasn't plugged in to the other, it worked(bike), plugged it gives errors that persist to a new controller seems like their wiring may be the fault.

Chain seems ok. Consider adding guards to prevent tetanus maybe
pablosanchezzzzz@reddit (OP)
I'm gonna replace it.
black-rifle-veteran@reddit
Your problem is put some damn oil on that chain it will run alot better
pablosanchezzzzz@reddit (OP)
Ok

The batteries are exceeding the max amp draw
Airzone_@reddit
This sounds pretty on point, should ask what’s the max battery output for amps on the bms
Refills323@reddit
Sounds like short when you plugged the lights back on perhaps it was drawing to much energy thats why the previous owner had them disconnected it, in the long run it couldve damage some cells in the battery ? does the bike run? Try disconnecting what you connected set the old screen and reset all the settings perhaps youll jump start it lol

Wiring harness must be damaged somewhere, is there any visible damage?
MickyBee73@reddit
I was thinking this too, or there's an issue with the battery
pablosanchezzzzz@reddit (OP)
What wires specifically should I swap out?
Alone-Season-7972@reddit
Should be able to contact manufacturer and get a complete wiring harness. If your headlight is causing errors i have to assume there's a compromised wire that's shorting something. It's fairly common
MickyBee73@reddit
Ask a local bike shop if they can take a look at it for you to see if there's a problem with the battery.
pablosanchezzzzz@reddit (OP)
I didn't see any noticeable damage when I did a check on it and it was working fine before I tried to connect the lights
Alone-Season-7972@reddit
Yeah I'd replace wiring harness. Usually pretty cheap
Murky_Interaction688@reddit
Oh weird your's has different connectors then mine
pablosanchezzzzz@reddit (OP)
What's the controller model # on yours?
Murky_Interaction688@reddit
8347Y with waterproof connectors
pablosanchezzzzz@reddit (OP)
Your connections are so much nicer wow.
MickyBee73@reddit
Try hooking it up to another Battery, E06 & E010 appear to be either a battery discharge issue, or a faulty connection to the battery.
pablosanchezzzzz@reddit (OP)
Battery is probably the thing I didn't want to replace lol they're so expensive.
MickyBee73@reddit
Usually the most expensive part of the whole E-bike.
If you can get hold of a battery (same voltage as what's in your bike now) to hook up to just try it first then you will know for sure, but these "E" error codes are all suggesting it's the battery.
If I power up my ebike build and switch off the battery the display will flash up "Error E06" just before the display dies (due to no power coming from the battery).

Did you check the lights to confirm they are working as they should?
pablosanchezzzzz@reddit (OP)
Yes the lights work fine and have no issues. Big one in the front turns on and the back one even has its turn signals working.
