Hypothetical question...
 

Okay, so I sell a working Prostock ESC on here.
I popped the fan back on, but in my haste put the connectors in the wrong terminals - easily done, they are unmarked.

The buyer hasn't checked the connections himself on plugging in, and has released some magic smoke.

He's blaming me it would seem.

Personally I would have googled it first, but that's just me - been burn't (pardon the pun), like this with second hand gear myself - the most memorable being a wrongly wired crawler esc...

What's your take on it?

cheers

Has he fried just the fan or the whole ESC? If it's just the fan I've probably got a spare knocking around somewhere here - drop me a PM.

Nah, turns out he had a duff servo AND sensor wire.

Thought it was odd as the output from the ESC for fan and RX is likely only 5-6v and a low amperage - and unlikely to work at all if connected reverse polarity - suppose the fan might run backwards, but the RX wire would simply not work as the signal and -ve are reversed.

Seen my nephew do this dozens of times after using his programming card.

"Uncle Julian, it's not working again..."
