I have a thunder ac6 and every time I turn it on it doesn't show any thing but squares what can I do to fix it
Throw it away and get a better charger. Sorry if that sounds rude, but that's my honest opinion. Is it really worth trying to repair a $30 charger?
BTW, support for non-Traxxas products doesn't fly here. This thread will be locked soon.
This is not Traxxas related in any way. You need to contact the manufacturer or vendor you got it from for help with support for their product.
