A while ago I committed the horrible sin of plugging a battery in backwards. A single puff of smoke came out of the esc and just as soon unplugged it. I corrected the problem and miraculously the esc turned on and functioned well.
The truck has been sitting for a year and I just got it out to try and sell. I took it for a test run and it ran ok. There was some motor clogging, so I unplugged and re plugged in the sensor wire and for good measure, put in a brand new tekin capacitor.
Plugged in a battery and turned on the esc. Cogging seemed to be gone! Then tried a better battery (higher C rating and mah) and the esc wouldn't even turn on. Charged the battery, but it only took a few minutes on the charger. Plugged it in, the esc turned on, then when applied some throttle, esc turned off and when released throttle, it came back on again. Then when I would turn the wheel, it is like the system is "browning" out. So I am scared the BEC is just about fried. Am I right, or am I not thinking of something. No shorts anywhere, all solder joints are good and battery polarity is correct. Problem seems to be worse with my two "race" packs than my practice packs.
Thanks for any and all help, and sorry for long post.
