I bought a Robart Electric Retract Conversion Kit for my TF Mustang at Joe Nall. Wasting no time when I got home, I assembled all the components/ hooked up all the leads and.................nothing. The status light on the retract control box remained red (no signal or low battery). The instructions say to remove a jumper in the Aux Battery receptacle and the plug the battery plug, via a charging switch into that receptacle. The A123 battery I have has two leads, one is a two wire lead and the other a three wire. I normally use the three wire lead for charging and the two wire for the battery plug. Out of desperation I finally plugged in the three wire plug and the system worked as advertised. However it is also powering the receiver and servos as well, even if the receiver switch is off. So....what's up? Why does the retract system require a three wire lead to operate? What is the recommended battery harness setup?

Unfortunately, the retract system instructions offer no battery hook up recommendations. Just says to remove the jumper and use a switch between the Aux Battery and the control box. My hope is somebody reading this forum has gone through this and figured out a fix.
