I am trying to install larger better lights inside my car, it runs at 3.5volts sometimes, and at 10.25volts sometimes. I am trying to take the voltage up to 12+volts so I can use a relay. I used a 32v 4700uf capictor and it gave it enough power to activate the relay, but then the car doesn't get enough resistance so it turns off the power thinking the original bulb burned out. So at this point I installed a .005 Ohm 50 watt resistor, and it didn't work. When I remove the capictor and only have the resistor connected it takes the load and the car doesn't error. So my question here is, how can I bump the power to 12+volts to get a signal to turn the relay on, and take the load coming from the car so the car doesn't think the bulb burned out and turn the signal off. Is there a way to make the power only go one direction into the capictor, would a diode do that? I am thinking the capictor sends power back into the direction of the resistor/car. Thank you guys in advance.
