Re: Re: Re: How to tell if a Capacitor is good ?
Huh? Do you know what a cap is for? If not, don't use one. Originally posted by pioneer y ?
right now i am gettin a small voltage drop...at idle...about 0.03 volts
You can test a cap by charging it up to 12 V off your battery (use a light bulb or resistor), then put a load on it and time how long it takes to discharge. There should be more than 37% of the voltage you started with after 1 time-constant.
t = R*C
ex. 1 time constant for 1 farad with a 100 ohm load = 100 seconds. So after 100 seconds there should be at least .37 x 12 = 4.44 volts on the cap.
