LI Unit won't turn on

[Tony Romo]

So I've connected everything as I was instructed. I ran the power cable into the fusebox, and attached it to an "add-a-circuit," where you pull out an existing fuse, plug it in the "add-a-circuit," plug in the additional matching fuse, plug in the red cable, and put it back into the fuse slot... then I grounded the black wire, and I don't get any power. I've tried many different slots.

You need to get a simple voltage tester, even the one with light only should work. You can then get more info on what is going on.
More than likey it is a ground problem.

Agree, a simple test light will tell you if you got good pwr or not. Worst case go via direct to the battery, thats how I set up mine.

why do I need to test it with some meter... shouldnt I know if it's enough by whether my system turns on or not? I've tried different fuses too...

does it matter how many amps? 7.5? 10?

I attached the ground to a black screw under the cockpit.... is that not ok?

How would I attach it to my battery?

Do what I did: Get a blue wire tap and that teal looking adapter that goes into the wire tap and where you can splice the red wire and crimp it onto that connector. Then I stripped the ground wire and found a bolt to ground to. Powered up first shot.

Is this to hook up to the battery?

No, I used the wire tap to tap into the wire that goes into the cigarette lighter socket.

Your ground wire must be something attached to a metal screw attached to a large piece of metal. My suggestion is to take that ground and open your door. Touch that ground wire to one of the big bolts inside the door frame, then see if you can get power to the unit. That is one way to tell if you have a bad ground which you most likely do. If you get power to the unit, find a different ground under the dash. The other is to get a multimeter and test for continuity.

For the ground, get a metal ring end and crimp it to the wire, then make sure to find a bolt that goes into the chasis to get a good solid ground.
