ready to run new boat. when i hook up neg to complete circuit there is no snap. sequence for startup is as follows: turn on transmitter . plug in bec to one of the packs. servo is on. neg of one pack to pos of other on each bank of batteries. connect remaining pos from each bank to t on esc. then hook up neg on each bank. there is no snap when i hook up the first neg to the esc. what's wrong? see picture. the esc arms and beeps 10 times and motor turns with throttle. no snap worries me.
