Step 3Test the circuit!
Test the circuit:
If you have a 12 volt power source at this point, you should hook it up to the inputs of the cigarette lighter adapter and measure your output with a multimeter to make sure your circuit is working correctly. If you don't have a 12v power source, you can put everything back in the charger casing and plug it in your car and test the output.
BUT BE WARNED:
If you messed up the circuit (grounded power for example) and hook it up to the car, you may blow a fuse (I admit, I've done this once or twice : ). If this happens it's not a big deal, all you'll have to do is replace your (likely) 10 Amp "Accessory" fuse, refer to your car's documentation for location.
