kev, how are batteries and capacitors not loads, they are part of the circuit and create resistance , specially capacitors all be it a very minimal resistance.

I may be wrong here and I apologize if i sound like I'm telling you how it is, I'm just looking for some clarification.

Just being part of a circuit does not make a component a load. For example capacitors and inductors are energy storage devices and do not consume any appreciable amount of power. Some energy is consumed through leakage and in moving energy into and out of them but it's laughable. I'm not sure what you mean by a capacitor adding resistance. The ESR (Equivalent Series Resistance) of a capacitor is extremely small. Negligible really. A properly connected cap will not add resistance of any considerable amount. Proper gauge wire and termination will make the junction resistance inconsequential. It will simply store charge when the system voltage rises and release it when the voltage drops (albeit not very much). Same with a battery but the method is different (chemical). Large batteries like found in a car also have extremely small ESR and again are negligible regarding power loss. Unless the battery is aging and needs replacement of course. Otherwise they just store and release. Hope that explains my position.

Sounds like a reasonable explanation, thanks. I'm still pretty new to installation and was just looking for some clarification
thanks

I dont doubt that someone has already done this lol.
