Wiring a Battleswtich

[Mouldy]

put a multimeter across the motor when u fire the switcher- whats the before and after voltage?

[ChrisKazoo]

0v across the motor, 15.4v across the switch which doesn't make sense? That's when it's being fired and when it's not

I don't think you should really be powering a large motor directly off a battleswitch. I think you need the battleswitch to turn on an automotive relay which then controls the motor.
I'd try connecting the motor directly to the battery to check both work.

[ChrisKazoo]

Only using the motor with the Turnigy switch cos I know it works straight off the battery and the solenoid is soldered to the Dimension switch. The solenoid didn't work on the Turnigy either

That is exactly what I would expect if the switch was wired correctly and in the off state. Just to be sure, does the motor run if you bypass the switch output with a length of wire? If it does, the power wiring is definitely OK.

The Turnigy switch instructions mention that it turns on when the radio channel its connected to passes 50%. Can you plug a servo into that channel and see it move fully in both directions?

With the battleswitch make sure you are wiring it like this: https://www.dimensionengineering.com...ch-diagram.jpg. Just replace the motor with your automotive relay.

The motor ran when I bypassed the switch, made a video of testing the servo and both switches:

Already done that. My only guess is that this connection is wrong but I'm not sure how else I could do it:

OK, that seems to eliminate everything apart from the switches

[ChrisKazoo]

I'll order another one, see if it is the switch :/

[Max]

For some odd reason all the diagrams I can find about the turnigy switch want the receiver and the main load to have a "common ground"- maybe that's an issue
With the battleswitch, could you upload a clear picture showing how it is wired to the complete system? I can't quite wrap my head around how you've done it.

There's a wiring diagram that Nick did for me on my build diary, might be worth a look to see if there's anything you can do differently.

I don't think a common earth is *required* for the Turnigy switch, but it couldn't hurt to try it at this point. This is the diagram that Chris refereed to:



Its pretty much the same as the diagram on the HK site. I always use a BEC to power the receiver so there is always a common earth whether its needed or not.

Chris,

Had the same problem, connecting all earth wires from battery(ies) reciever and switch should sort the problem.

Hi guys, also having a problem with the turnigy switch, I've wired it to an 850 motor via an automotive relay following Nick's diagram as best I could. Not getting anything at all so either I've wired it wrong or there's something wrong with the switch or relay, any help would be great. The relay I'm using is http://www.sunhold.com/product_2.php...O3=59&Vcode=31and here's a pic of how I've wired it all up, not all that clear but if you can spot any problems with it that's a help.

So after a bit of testing still nothing, it's not the tx or rx and I've tried with 2 different batteries, it's either that I've wired it wrong or there's a problem with the relay or switch. Here's a top view of the relay with the numbers and symbols, if anybody can tell me how to wire it up using that so I can see if I've done it right that would be great.
