[QUOTE="tamrat, post: 459098, member: 29874"] Hello John, its not mF (milli farads), it's uF (micro farads). 6600uF is the total capacitance I used (as per the steps in the link). I couldn't find a single 6600uF unit therefore I also purchased 3 capacitors each having a capacitance of 2200uF ([I]but they were marked with 16V on them [hmm....][/I]) and wired them in parallel to get a total capacitance of 6600uF. I don't know much about capacitors so I don't know what their voltage rating play here. Maybe its the maximum potential difference that can be stored on the capacitor. When I tested it, the values were perfect, I have no other word for it. A brief tap on the positive terminal of the battery was enough to charge up the capacitors to 12V and they kept the relay energized for about 2 seconds. Which is more than enough considering power will come and go in about 0.5s (maybe) intervals when turn indicators are being used. Tamrat, [/QUOTE]
