Default blown esc or receiver???

Hey guys I was try to install a fan for my motor but i needed to cut a three prong fitting to connect to the fan so it would connect to my receiver. I had the one connection in my receiver with the wires exposed and was testing the fan to see if it worked by touching the wires together. Well i guess the neg and pos wires connected to the receiver touched because nothing turns on anymore. Are both the esc and receiver blown or can it just be one of them.

Try a new or different receiver. If you get power to steering and throttle, then you'll know the problem.

Unplug the ESC from the receiver. If the ESC is still dead then start there.

If your radio came with a battery harness (like for Nitro use), or you've got a friend (or your LHS) with a receiver pack or battery harness, try using that and leaving the ESC unplugged. If you get steering, the receiver is probably OK.

If your were testing with the ESC on, then you shorted the pos and neg together. The result is fired BEC in the ESC. if nothing else was fired the esc would still turn on but there will be no power to the receiver and servo. So in this case there is more damaged done to the ESC other than the BEC and it is not quite user serviceable. probably the ESC need to be send for serviced.

The pos and neg of all the slots in the receiver are soldered together.If you shorted them together, it was a direct short at the input , thus the receiver should still be fine.

dude, is your receiver 2.4Ghz? i find these new receivers not robust like the Ams and FMs of yesteryears..i blown a receiver recently, latest airtronics one coomes with the MX3, just by accidently short circuiting the batteries.
a few months ago when i was using FM receiver, i accidently short ciruited the batteries, and my receiver was fine, but i blew the ESC cable going to the receiver, simple enough, i removed the ESC, opened the casing, and desoldered the 3 wires and changed to a new one with a new connector, it was working again.
