Electronic failing

[SpaniardCrawler]

Hello guys,

I will try to explain my problem as good as I can...

Ive a waterproof esc like goolrc, from China.

After months with the rig stopped due axles upgrades, the esc doesnt beep when I switch it on as usual, it sounds like a going down beep... also the tactic receiver is blinking and it’s not possible to do anything to pair or whatever...

I guess I blew up everything but still don’t know how, why...

Do you know the meaning of this go down beep?? I didn’t find anything like this in the esc manual.

Unplug the servo, then check if motor works.
Look in motor holes for black wire, that's generally bad.

Try to isolate components as best you can to eliminate problems.

Unfortunately, the no name esc's are very hit & miss. My son had a brushless "GoolRC" esc fail after 2 outings, several other friends have had them die in short order too... but their motors seem fine (not much to them.) I've had bad luck with the pre-installed T plugs that don't seem to make a good connection until you plug/unplug the battery several times, switching to genuine Deans plugs (or your plug of choice) cures that issue. That being said, there's still a chance that it's just a faulty power switch, in which case, you can just cut it off, solder the 2 wires together, and it will effectively always be switched on (your battery will become your power switch.) I'd start there.
