A capacitor of 0.5 Farad should have screw or spade terminals, with clear polarity markings. POLARITY IS EXTREMELY IMPORTANT!

The "-"/negative terminal needs to be connected to ground, while the +/positive is connected to the vehicle power. Reversing polarity will cause the capacitor to explode.

You will also want to charge the capacitor initially through a resistor to prevent blowing a fuse/breaker. A 100 ohm resistor will keep the current below roughly 100mA during charging. Let capacitor charge 15-20 minutes if it is a fully discharged capacitor. Once charged remove resistor and connect power cable directly to capacitor.

Once charged, large capacitors can dump large amounts of current, creating a fire hazard! Ensure all connections are well insulated once connected, and the power cable is sized to match the power of the component.

How do you hook up scosche 500k micro farad digital stiffening capacitor?

assuming you have an amp. run the hotwire from your battery directly to the POSOTIVE terminal of the cap. the run another wire from the POSOTIVE cap terminal to the amps power input( where the wire went before) and the run a third wire from the caps NEGATIVE terminal to the car body(as a ground) i have one in my car it wrks good for about 500 watts after that u need stronger cap. good luck

Why does the Fuel pump keeps running on your 92 explorer?

have you checked your computer? If your pump stays on when you first turn the ignition; without turning on the engine, the pump usually turns off after a few seconds. If your pump stays on then you can suspect the computer. Remove the computer. Remove the two Torx screws and open up the box. Then look for three capacitors. Two will be 47 micro farad 16 volt and the other will be a 10 micro farad 63 volt. If they look bloated or like they are leaking some black stuff or if the leads are detached from the PC board; replace them. You can get the capacitors at the radio shack. The trick will be that you have to buy two 4.7 micro farad capacitors in the place of the 10 micro farad capacitor and wire them in a parallel configuration. The reason for this is that they do not sell a 10 micro farad with the VOLTAGE rating that is required (63 volts). This is the only capacitor that requires a 63 volt rating. MAKE SURE THAT YOU BUY "POLARIZED" CAPACITORS. Hope this helps

How do you hook up a 3 farad capacitor to two amps?

**** caution**** very much danger......on the cap there should be 2 terminals....+ and a - .....first thing is to undo the power supply the cap goins inline on the (+) side of the power supply and also hook the (-) to the ground inlined with the amp......do NOT EVER EVER EVER TOUCH OR ARC ACROSS THE CAPS TERMINALS....THIS CAN BURN UP THE CARS ELECTICAL SYSTEM AND OR KILL YOU BY STOPPING YOUR HEART.......SO HOOK THE CAP IN BEFORE YOU HOOK UP THE (+) POWER TO THE SYSTEM
