Brocken receiver
Hi, I have just broken my receiver and I am not entirely sure how, either I shorted it by putting it in my metal robot and shorting it across the pins. Or it could be because I plugged 2 electronizers in so it could be they both tried to power the receiver giving it twice the power it needs overloading it and making it fry. Which do you think it could be?

Re: Brocken receiver
Do both Electronize's have BECs? That wont normally blow it anyway, normally messses up the speedos/BECs. Shorting the pins is more likely it, especially if it was a signal pin. If it has blown, chances are its not worth bothering trying to get it fixed, only easy fix is if its burnt out the track on either the + or - rails (assuming its not taken anything else out).

Re: Brocken receiver
Turns out receiver is fine! Unfortunately that means something else is broken, I hope it is not my electronizers. Do electronizers have becs?
-
Re: Brocken receiver
depends if you bought the ones with BECs, if not what are your powering your RX by?
-
Re: Brocken receiver
You only want to power the reciever from ONE of the Electronize controllers ...
-
Re: Brocken receiver
How do I stop power coming from the other?

Re: Brocken receiver
This is a pic from another thread.
Joining the orange and red leads turns ON the BEC ( Battery Eliminator Circuit ) .... simply disconnect one pair IF you have two Controllers with built in BEC's.

Re: Brocken receiver
I don't think I have one with a bec, that is anoying-I will have to use my receiver battery. I wonder what happened to the receiver if there wasn't any power going to it-it definately smells of burning
-
Re: Brocken receiver
The reciever definitely shouldn't smell of burning.
Just to reiterate only ONE reciever power supply is wanted.
Here's another pic showing the internal track connections of the reciever...note ALL the negatives are connected as are ALL the positives ...only the signal pins are seperate.

Re: Brocken receiver
It could have shorted across the positive and negative pins, but if there is no bec then there would have been no power at the receiver so it couldn't short circuit

Re: Brocken receiver
Have you actually powered it up?
-
Re: Brocken receiver
I wired them up to the motors and receiver and plugged in the batteries but I was unable to control the motors and the receiver sparked and smelt of burning and got hot so I unplugged the batteries
-
Re: Brocken receiver
did you plug them in the right way round?
-
Re: Brocken receiver
Wire up the controllers to the receiver with just the yellow signal wires and the black.. NO red ... and a seperate receiver battery.
-
Re: Brocken receiver
I think I plugged the batteries the right way round, I will have to check on Thursday as I left it at school. I will also bring in a receiver battery and try just plugging one in and see if that works
-
Re: Brocken receiver
did you plug the things the right way up in the rx?
-
Re: Brocken receiver
If your speedos don't have BECs i cant see how you can have blown the RX, unless something has been wired very wrong, even the power to the speedos will only blow them and not the RX.
-
Re: Brocken receiver
The rx is fine, just smells of burning. I've got the FR30HX so I don't think it has a bec. I will have to test. Maybe the becs have blown in the electronizes if they have one.
-
Re: Brocken receiver
I am 95% sure the 30a model doesn't have a BEC.

Re: Brocken receiver
I did more tests, I used a rx battery and everything kind of worked. But tue rx and the wires going to the rx from the electronizers. I tried removing the red wires but then the motors wouldnt turn. I am not sure if the receiver is the problem or there is a problem else where which affects the receiever. Towards the end of my tests one of the channels stoppe working properly and then stopped all together and the other channel also went odd.
The electronizers made a clicking sound when the motors turned, is this normal?
-
Re: Brocken receiver
yes, thats what they are ment to do
-
Re: Brocken receiver
The clicking is the relays inside, they will click when you change direction. Which red wire did you cut, the power wire or the signal wire? Depending how the electronizes are made, the chance are it will need power form the RX to run the logic side of the controller. Regarding it cutting out at the end, have you checked the batteries? A picture would be helpful of your setup wired up.

Re: Brocken receiver
The batteries may be running low on charge but it still doesn't explain why the receiver and wires got so hot
