Need HELP wiring CC BEC into battery wires

I'm really bad with electrical stuff and wiring..

I just got a Hitec 7955 and a Castle BEC and I'm very excited! However I need help..

I'm running a Traxxas XL-5 ESC so it's got the Traxxas high current connector.. How do I wire the BEC into that battery wire?? Can I take apart the connector and put the BEC wires right into it and close it back up or????

Also the diagram shows plugging the BEC into the 2nd channel on my reciever.. but then what do I do with my servo plug???

You can splice on the wires outside of the Traxxas connector. The BEC cable can then plug into the batt port of the receiver. Either take the red wire out of the cable from your ESC or DO NOT turn on the ESC. It will power up when you plug the battery in via the CC BEC. Confused yet?
 
There are several threads regarding this issue already, but here's how I did mine. I made a small extension with plugs on either end (I use Deans),which I refer to as a jumper, between the esc and the battery. I removed a portion of the insulation around the wires in the middle of the jumper and soldered the bec wires to it and shrink wrapped it. This way I didn't effect the battery or the esc and if I ever want to remove the bec I can just remove the jumper.

Also, I bought a 3" jumper for my servo wires. I did this so that when I removed the red wire I didn't mess up my bec wires. I just removed the red wire from my 3" extension. I plugged the bec into the 'batt' input, not the #2 input.

You have to buy some wire, connectors and the servo extension but it makes it easy to remove if for some reason the bec goes bad and doesn't effect the battery and esc lines.
 
Hope you have better luck than I do. Ive had 2 of them and neither has made it thru one battery pack, and yes it was wired right. Even took it to a electronics genius I know and he said it was wired right so did hobby shop owner. I wont use one again. Was told you really dont need them anyway.
 
I've never had a problem with my Castle BEC....I hooked it up the Rocksmith way, not the Castle way.
Works great"thumbsup"
 
I got home from work at 1:45am. (2nd shift) and I just finished soldering the wires on and pulled the red wire from the ESC and plugged it back in, and finally plugged in the BEC.. I don't like that the servo now has power as soon as I plug the battery in, but that's ok.. Because HOLY COW!!!! That servo moves those wheels with AUTHORITY! Hah. :shock::shock::shock::shock::shock::shock::shock:

It's even faster.. A LOT faster lock to lock.. There is no binding of the steering from lock to lock so I guess I don't have to woryr about burning it out, seeing as how I'm using a POS radio with a digital servo.. I adjusted the center so that the knuckles are an even space from those little screws on the Axial axle that holds on the axle "C's" so I should be good to go.

I also ordered the Castle link so I can adjust the voltage output. I'm safe upto 6 volts from what I understand.. I think I'm going to try it at the default 5.1v to start with.. Though as an experiment I also want to try my old Hitec 645 at 6 volts to see just what a difference this BEC might be making.
 
I have the CC BEC plugged into the batt port on the RX, and the ESC's red wire is disconnected and heat shrinked out of the way. However, every time I connect my 3S Lipo, the RX and servo are immediately powered up. This essentially makes the switch on the ESC useless. More concerning to me is that I hear a faint "pop" noise from the Deans connector each time I connect it, and I'm worried that the sparking that might be occurring is hazardous to my Lipo's (and my own) health!

Has anyone wired up a switch on the battery input wires to the BEC so that you don't get any sparking when connecting the battery?
