Hello, I purchased an ETWOW S2 Booster+ which is known to not power on. I am attempting to troubleshoot the scooter. The scooter will not turn on with battery power or if plugged into the charger. So far I have replaced the connector module, data wire, and LCD display. After replacing the parts the charger functions properly (turns red when charging battery, then changed to green when fully powered). The voltage output of the 33V 6.5A battery is 36.6V. Since I have replaced nearly all of the electronic components I am a bit puzzled as to why the scooter is still not turning on and am seeking additional support. I did not there seems to be 2 LCD screen batteries which could potentially be replaced or perhaps there is an issue with improper wiring of the components. Thank you in advance.
