Need Help with single FSESC running a BDUAV 6384 120KV & 12v SLA Batt Setup

Greetings to All,   


First time post and quite a newbie so please forgive is this is not the correct location to post.  I'm working on a project for a slow-moving "push" vehicle and have issues gettiing the motor to spin.   I've using a FSESC 4.12 ESC, BDUAV 6384 120kv motor and a 12v 20Ah SLA battery.  


For starters, the BDUAV motor has only 5 for a sensor wire.  From some research, I found that it does not have a temp sensor, so I've changed the motor sensor wires to reflect the following:  +5v(red) TMP (blank/no wire attached)  H1(orange) H2(white) H3(yellow) and -(black).

From there, I ran the VESC Tool and attempted to set up the esc.  I'm using a hobby grade Futaba T14 radio and FMR-02 receiver.  I can connect to the esc successfully, choose the PPM input option (with the icon of a RC radio) and see the PPM mapping when I move the proper stick on the radio associated with that channel.  For this application, I wish to use the esc as FWD-REV, as such I tried to use the PID speed control option.  When I'm finished with setup, the motor will not spin, only a bit of a whine and what seems like an attempt to move in either direction.  


I'll add that I tried to do the SETUP Motors FOC, where I also set up the battery type and 3S  with 20.0Ah but cannot complete as it gives an error that there is a connection missing when attempting to spin the motors.


Any help would be greatly appreciated,

while unloaded motor, use motor setup wizard. you could update fw to the latest one, if you like.
