I have a arrma infraction all stock cept optional pinion and motor fan. So It was just a regular day and running the car with a 6s high voltage battery for a few runs and then car dies out. Thought it was the battery going dead so charged the battery, and saw that it had a good enough charge . Switchit on and nothing turns on. Tried multiple good batteries , nothing turns on. Open the esc and see a black liquidy substance near the capaciters. No hard impacts at all had a small one with another rc but kept running. Could it be the switch or is the esc bad. Specially does anyone have the black looking gluely substance near the capacitor when you open up the esc? Just wondering if this this normal. Any help is appreciated. Thanks in advance
