Unfortunately for our new racing class we´re forced to switch to the LRP X12 motor, which is a mess in my eyes.
Well, I bought a used one from 2011, which should not have the actual problems (another theme).
So I tried it today on the table, motor came with the 4 dot insert.
Adjusted the esc, test the gas, everything seemed normal, with or without sensor cable, only the r.p.m. seemed to be a bit low (from the sound).
Suddenly I smeeled something burning, and my capacitor smoked up and the motor began to rev slowly without getting a signal. End of my beloved esc, probably.
Please, if you had similar problems, what could it be?
Is the sensor cable from LRP any different to SP? Also running GM motor on it and never had an issue! Sh** LRP stuff...
Help very much appreciated, as I don´t dare to connect it to my GT pro now...
Best regard,
Matthias
If I were to guess I'd have to say that there was probably a short somewhere in windings on the motor.
And as far as it being cooked, it could just be the cap, it could be the whole ESC.
First thing I'd try is running a different motor, doesn't matter the wind as long as it's within the limit, on that ESC. Replace the cap with a new one and wire up as per usual. If that's not the ticket then next I would test the motor with a voltmeter to check the wires.
If one reads funny, the motor cooked the ESC, and it will probably continue to do so on every unit you use it with. If it reads fine, might have just been a short elsewhere, make sure when you re wire it all that everything is by itself, nothing visibly touching.
