Tekin G12 esc keeps blinking, nothing else?
 

So, been out of the sport for a few years, decided to hook up a Tekin g12 in my sons truck. Wired it just like I did for my g9, but with the g12 the red light blinks constantly, can't program and nothing else is showing signs of life? Any idea of what it could be? It is used, so Im not the original owner. Looks to be fine, but who knows. Thanks!

I believe steady blinking with no response means no radio signal. Make sure the black wire is to the outside of the receiver at the plug
