Sea King 180 up in smoke

[sanyijr]

The motor could have shorted out internally and fried the ESC too. If that's the case, you'll fry the next ESC you hook it up to as well.

Be careful. If the motor stutters when you try it on another ESC with fully charged batteries STOP right away. You may wind up letting the smoke out of that ESC as well.

Stinger9D9, is that the Offical way to test if a motot is shorted out? Any other ways to confirm before you risk frying an ECS?

I don't know if there is an "official" way to test if a motor is shorted, I just know that's how it happened to me on a new AQ 1800 kv motor with 2 runs on it. It fried the ESC, which then overvolted the receiver and took that out too (with a tremendous flash I might add).

You can buy some Multimeters with an Inductor Testing feature, then you check between each phase, I had an Ammo 2300KV let go, and when I checked it, you can see that one phase had shorted by the difference in readings from the other phases. Take a reading of your new motor first, write them down and keep them somewhere, then if later you think your motor is bad, compare the readings.

Can you elaborate on this ; step by step ? I have a Fluke 77 but am not savy on what an Inductor Testing feature is. Be good info to have on hand.

Thanks,
