    Post what needs a fuse?

    hey guys im going to make a mp3puter for my car. I was wondering though, has anyone messed up their electrical system while doing this? Do I need to put an inline fuse on the inverter or does it have its own shutdown system? I have a camera that I am going to be attaching to the battery. should i put a fuse on this? Also, when I shut down the car, will the camera still be turned on since it will be hooked straight to the battery? Maybe I should hook the camera to the power on wire of the cd player so it turns on and off with the ignition. Oh ya, I also have a Santeca TV tuner thats an actual car tuner. Should this be hooked straight to the battery or to the power on wire of the cd player?

    pardon my ignorance, thanks!

    Cool

    Everything needs a fuse. You should never connect anything in any electrical system without being fused. To do so is to invite hazard.

    oh ya, does it matter what kind of fuse i use. I mean should i just use a 30 amp fuse if something only needs a 15 amp fuse?

    Cool

    Connect the camera through a 12V regulator so you don't kill it with an over voltage. You didn't mention what kind of camera it was, but odds are you can get away with a 5A fuse.

    Are you saying that the odds are his camera draws 60Watts of power?!

    hello to aaron cake--one of the pioneers here!

    i would put a fuse for everything i added as close to the power source as possible not the unit being powered. remember fuses protect THE WIRE

    Comeon guys, this thread is 4 and 1/2 years old and was dragged up cause the guy said he could use a 5A fuse? (When yes, he could probably do 1A or less)..
