Power Issues

revised diagram with additions.[attachment=0:35pf65wk]bat%20motor%20controller2.JPG[/attachment:35pf65wk]

I am measuring 18v on the red and orange wires coming out of the ESC on both.

My wiring matches your 2nd diagram except that one of the BEC's is connected to the reciever.

Emailed the seller, said he had only disconnected one BEC (although both produce and voltage) and had made no other modifications. Have now emailed Electronize to see if they can figure this out.

what do you mean by one of the BECs is connected to the RX?

Am I missing something here?

I thought the BEC on the ESC suppiled a 5v output that you then connect to the battery input of the RX, eliminating the need for another battery pack?

Hmmmmmm...possibly

My 2nd diagram is correct....and the BEC IS CONNECTED ON ONE CONTROLLER ...the other is OFF.

OFF = red and orange wires not connected together.

How does yours differ?


NOTE :-
Joining the red and orange wires together simply turns on the Battery Eliminator Circuit
The 5v from the BEC is then supplied to the receiver via the small red and black leads......If you put a switch between the red and orange wires you could turn the BEC output ON and OFF


So ...just to be sure

The orange and red wires are NOT the BEC ... they are the means to turn the controllers BEC ON

I have the red black and white leads from each esc connected to the RX and then the yellow and orange wires from teh BEC connected to the battery input of the RX. In your diagram one of the BEC's has the yellow and orange leads connected together.

You don't need to plug your yellow/orange BEC wires into the receiver. Just join one pair of them together and leave them like that. This activates the BEC function on the speed controller (just think of it as a jumper that uses wires instead of a little black connector) The 5V supply that provides the power to your receiver is then supplied to the receiver through the standard red/black/white RC connection cable from the speed controller.

Really! How strange............ Ok, well I hope my RX is intelligent enough to take power from one of the output ports...... Strikes me as a very odd design, but does answer a few things....

So I'll try that then. Is it likely that, that will have something to do with only 5v coming from the motor leads?

The negative pins on your RX are all joined to a common rail ..likewise the positive pins are also on a common rail.

The signal pins are however seperate.[attachment=0:fxaljwyq]Bz78636.jpg[/attachment:fxaljwyq]

As per my drawing you only want one positive and one negative from your controller/s to the receiver....and both whites ( shown/drawn as yellow in my pic )

Right! I get it now! Thanks everyone.

Ok well Ill have a change around and get everything wired as it should be.

I'll see if this helps the low output from the ESC. Process of elimination, one thing at a time.......
