Our track uses PT's (amb) for house transponders, plugged one in today that had very questionable wires going into the case.( didn't notice till it was too late) Well guess what all my servo and esc leads went up in smoke. Question~ if the PT wires short is this the end result?? Everything else was the same from the prior heat other than the PT with the bare wires....

Man that sucks bad. You know if I do something silly like put a 20s lipo on a controller meant for no more than 2s and I cook it I can smile because I had fun and I knew what I was doing. But hooking up club equipment and having it melt my car, I think I would be furious. That could definitely cook some things if the wires were shorted. Im sorry to hear about that. Im sure if the stuff that fried was good equipment then the company may help you out. I wouldnt expect them to replace anything for free, but maybe they will cut you a break.

Yikes, condolences. The servo part is weird, problems with the esc is understandable since it’s supplying the power, even though I would of guessed the BEC would blow before melting wires. I could see possible problems with the receiver power connections too.

But the servo, would of thought it would basically act like it was not powered/under powered, that’s weird. Unless damage to the receiver dumped voltage to the signal wire?

Suggest being careful with the receiver, try to check the voltages on it before connecting a servo. Perhaps the same with the ESC without the receiver, take it one step at a time. Maybe start the receiver checks with the AA receiver battery instead of the ESC for power, and feel for heat as you go. Good luck.

Ouch!! Know you didn't need that happening!!

My bad, I need to clarify a little. The wires all melted because of how tight they pack into the receiver case on a slash (cover was off but wires still bunched together). lead on the ESC was fried the worst, and the lead on the PT was next. PT lead was plugged into a servo extention and it melted together to the point that when I pulled it out it stripped the ends off the wires. Yes I was pissed but the track owner is a good friend of mine so I just kind of let it go. Honestly I'm normaly pretty anal about my stuff AND I knew the wires on the PT were a little questionable but in the rush to get both kids ready torace I just let it go...OOPS. I'll give an update once I test everything, only part I really care about would be the receiver...

outch!
What ESC has that much BEC ?

Sorry to hear, if the BEC on the ESC isn't toast, there may be some hope.
The only bad part would have been if a + or - got into the "sensing" wire on the servo or ESC...

If it were me, I'd get a volt meter & hook to the red & black leads on the ESC receiver connection & check for "normal" voltage 5.5, 5.7, 6volts?

If the ESC tests good, then connect to the receiver (no servo) & test.
If the ESC gets signal, then try the servo...

Like Dave H was saying...
If you really don't trust the receiver, a RX pack & a servo will tell you if the receiver is good, & you can test the servo...
The regulator in the ESC may not take another hit like that if something is still shorted...

Update! PT leads were fried the most (that's where the short was) all the other wires seemed to melt from being in contact with PT leads and not from shorting out themselves. The receiver is fine (sr3000) and esc is fine with a new lead on it. Servo is also fine. PT is dead but that's o.k. because that's the only part that wasn't mine..

I assume thats your newest family member??

Took me a little while to make the connection....duh....



Congrats!!
