//// Any damage if a 4700uf capacitor with power & signal?
I have an important question:
I was experimenting to see if a 4700uf capacitor would help. I accidentally plug it backwards with the capacitor negative lead to the signal side servo lead of the HC3-SX (4th cyclic servo port).
I've never used that port and don't know if that port is damage but the the rest of the cyclic is working.

The HC3-SX itself didn't initialize but tried a few times.

Could I have damaged anything by plugging it in backwards?

This is if you reverse the Glitch Buster's + with the FBL's - completely.

I just plugged the Glitch Buster's - to FBL's Signal.

The cap is probably damaged...I'd replace it.

Did it "pop"?

Usually an electrolytic cap(which is polarized) will pop or the can will be distorted.

I doubt you hurt anything else.

FWIW

Again ... The capacitor's input polarity WAS NOT reverse.

I understand that part. The cap's positive still saw center pin (+) and instead of ground pin ... I plugged the other side in the signal pin of FBL instead

Hence ... The capacitor did not pop and still functional.

BTW
I was told by some that since the capacitor was not charge, no harm could be done.

Even tho the capacitor is not charged, it may well caused a surge current into the control port and damaged it due to the cap charging from the Vcc (center pin +) to the control port.
That size cap would be like connecting Vcc to the control port directly for a 1/2 sec or so.

EDIT: I don't know if connecting Vcc to the control port would cause damage, but that cap may have done the same thing.
I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Misread you post, sorry.

I would agree with the above.

Most output signals that originate from internal microcontrollers etc. will usually include series termination resistors of a few 100 Ohms.

Often one of the functions of these resistors is to limit the output current in the case of a short (if chosen appropriately) to a value within the maximum spec of the microcontroller etc. So generally speaking these types of "accident" don't cause any damage...
