Yeah, all you get is a spark that will mar the caps terminal though.Spencey said:use a resistor, if you hook it directly with the cap fully discharged it shorts your electrical system
you do realize when you don't charge them if they aren't already holding charge, power flows un-impeded through the cap creating a short? Charging a cap up to a certain voltage isn't going to insure it stays at that voltage, its always going to be at the voltage of your battery, it just works to oppose a change in voltage between the two devices.MySiIzFaster said:i never heard of having to charge a cap before u put it in. I have an audiobahn 3 Farad cap and it didnt need charged.
Well, Im not sure what to say. I didnt charge mine, and it keeps the voltage a lot more stable than it did....maybe I lucked out.Spencey said:you do realize when you don't charge them if they aren't already holding charge, power flows un-impeded through the cap creating a short?
