Hello, I hope someone can help me with this. I would like to add a 3 way switch to my capacitor. EG. position A would be off. Position B would be on, and Position C would charge the cap. Is this possible?, How would you go about and wire this?? This will be used in my car, the Cap is 16 volt, 20 volt surge with digital top. The cap will not be inline to the amps, It will be connected to a fused distrobution block. I would like to interupt the power line from the distrobution block to the cap with the switch. I am assuming you would need a heavy duty switch to handle the amperage load. Any information would be great.

Thanks Greg

thats possible, but im not sure why you would want to do that. A simple heavy duty SPDT switch would do that, but you really need the cap connected in parallel to the load to be effective.

I have installed a switch on one cap, due to weird driver. He would play his radio with the truck off, and w/o the cap, it was enough to cause his amp to start turning off when the batt was about dead. (but truck would start)

But when he added a cap, it would discharge the battery enough that the truck would not crank over. So he put a switch on it so he could turn it off so he knew when the battery was going dead.

Me personally would not do it if it was my vehicle, but thats what he wanted.
