Here is a Pic of the under side of the Bms
I have circled the possible cracked connections .
Hello people,
It has been more than 300kms since the fix I showed you and the bike is running fine with absolutely no problems with the battery. So, be aware that there might be bad solder connections on the BMS board if you experience problems.
Regards
If it seems to be a general error with faulty solderings on the BMS you can get a new BMS as a Goodwill Warranty from the supplier, they rather takes som extra small costs in the beginning , will cost more if lots of customers start to spread that fact that the circuit boards is of inadequate quality.
I am SOOOOOO annoyed that people who have dealerships with those bikes have absolutely no idea about them...
A couple of weeks ago I went to help a friend who sells the E-go2 by goodyear. They had tried all ECUs of the bike and couldn't find anything. It appeared that there was no power in the front of the bike because of a bad cable. Problems in them are easy to be fixed. Just use your head and a multimeter.
If you are a dealer you can take parts from another bike and test in the troublesome one. So you end up with logical conclusions to the problem and get it fixed...
