I have some lights behind my grill.. they have been working fine.. and i also have a backup camera attatched to the line of power.. and now my fuse keeps blowing, like the lights will work for a while, and then the fuse blows.
its currently on 15a, what should i do??

their not powerful lights like the hella lights etc, just small rectangles

 

need more information to actually help. Where is the power coming from? are they direct power to the battery with a toggle switch inline and the fuse to the lights? Water in the backup camera? When the lights go out, does the camera still work? anything else go out? with something like this, the more details you can give the better.

 

If you don't have a multimeter disconnect the camera temporarily and see if that stops it. That will give you an idea where the problem is, if they work for a while before it blows it's probably not a short, unless they blow when you put it in reverse? Why not tap into the trailer power for the camera? That's a long distance to run the wires when it's accessible right back there.

 

For the camera, you should tap into the reverse light circuit. When your backing up is when you need it on anyway. That is what I am tapped into for mine.

 

Power is coming direct from the battery, and through a relay that works from the cargo light and the cargo light button.

I will hookup the camera into the reverse line and see what happens.

 

And where can i tap into to get it to automatically switch, right now its on manual but i have the wire to hookup to the reverse line feed, where could that be??? thanks.
