The other day I was charging my batteries and my power supply let out a little "puff." I cracked open the power supply and discovered one of the capacitors was shot (blew out the top, the "puff" sound).
I went over to radio shack and picked up a 1000uf 35vdc capacitor to replace the 1000uf 10vdc capacitor that had blown. Initially I soldered it in reverse polarity and tested, no dice, I switched it to the correct way, still no luck. I also replaced one of the wire bridges as it had blown along with the rectifier. I am about to throw it in the trash but I thought I would post to see if anyone has another idea on how to fix it.
The second picture shows the new capacitor in place, reverse polarity. I don't know anything about capacitors and if they would be damaged being reversed. Also, I noted that a wire looked as if it bridged over a resistor and was cut or if it was also blown out like before. I just don't know why someone would put a wire bridging a resistor, why put the resistor in at all?
Weather is great and I would like to get flying, otherwise I would just wait the few weeks to get a new one.
