ESC wires cooked

Hi there,

i would like to know if anyone had the same problem as me in regards to a new Turnigy TrackStar 1/10th Scale 60A ESC i had to replace on my HPI Porsche 911 GT3 as the original ESC failed and the wires keep melting at the ends where they connect together, so i keep soldering them back on
is there too much current flowing through those wires or whats going on???

HELP

What motor? What gearing? What battery? It's either a cold solder joint, or you're pulling too many amps through the wire.

Where exactly?
At the ESC, at the connectors (3.5 mm bullets), at the motor?

BTW what do you mean writing @HK: "it cooked the hell out of my motor wires conected to the ESC wires also keeps coming loose everytime from each other"?

I lost somewhere my magnifying glass and I'm not quite sure what your tiny picture presents but I bet on a bad soldering or connector mismatch.

Not too familiar with that car, but a 32T pinion sounds very large for a 5900kv motor... how were the motor temps?

Define "quite hot, but ok to run"... sounds like it's too hot, but not quite into thermal shut down on the ESC?

In any case, it's either cold solder joints (or crappy solder), or you're pulling more amps than the connectors can handle. I would remove all the old solder and solder it all back together with high quality silver solder. If that doesn't fix it you'll either have to drop a few teeth on the pinion to keep temps down, or get connectors capable of handling more amps.
