alex,

as i mentioned on the phone the other day, im no expert but the relays do click when powered up.

On all my robots when you put the link in the fire solenooids fire. Hence I never put my link in with the gas turned on, or i end up killing myself.

Ive done it once with the old ripper and learnt the hard way.


2 solutions as far as im aware,

1) wire it up so it sits on the lower limit switch.
2) fit an seperate receiver battery, when this is turned on , it will power the relays, ready for then safely putting the link in

Maybe woody can help?

[tom_kane]

didnt you do that yesterday Jonno, when ripper fired?

[robotwars]

no, in the words of jethro...

what happened waz...

I had a gas leak, so I place my shiney metal adjustable spanner inside the robot, and caught it on the spec receiver shorting out the exposed non used pins where the reciever wires go in....
saw a spark, and heard a bang !!

Scarey but another lesson learned!!

Alex ..Try something simple first and let me know the result.

Swap over the wires going to your lifter motor.

Note that Ive never owned an Electronize switcher.
But they should have 3 functions...BOTH RELAYS OFF with the stick/Switch central being the one that appears to be failing.

This is indicative IMO of the Spektrum failsafe being wrongly set...there shouldnt be any signal sent to the switcher by the reciever other than the OFF or neutral signal untill the transmitter binds to it and tells it otherwise.

What happens when you failsafe in Tech check?

One more thing that you could try just to make completely sure that its a duff reciever signal and not some other random event.
Disconnect the Electronize switcher from the reciever...then try powering up.
NOTHING should happen at all with the Switcher disconnected from the reciever.

they have two relays,

each relay has a common pin, normally open, and normally closed.

Its not a spectrum thing as it has always done it for me while using 40meg.

I know there is a fix, as someone told me years ago but i dont remember.

maybe something to do with how you wire into the switch, swapping inputs and outputs.

they failsafe normally, no clicks or anything,

Its just when you power them up ( via a reciever ) that it clicks.
Its like a pulse goes through the switcher and fires the relay.
