no power...to anything...nothing.

I was driving my car for a couple hours last weekend and after pulling into the garage and turning it off i have no power to anything. None of the lights work, nothing happens when putting the key in. Absolutely nothing.

I am getting 10v from the battery so at least the lights should turn on. I also tried the battery from my daily driver and still nothing.

I checked the main fuse which was good and also replaced it and still nothing. I assume I should be getting battery voltage at the black wire on the main fuse? I wasn't.

I have the battery relocated to the driver side bin and it's been working fine this whole time. I removed the battery terminals and touched the wires directly to the battery to see if that would make any difference and it didn't.

I ran a new ground for the battery and still nothing.

I am out of ideas. What else could it be? As I said, I was driving it last weekend and everything was fine. I swear to god this car hates me

check your power wires coming from the battery i had a similar issue the wires had burnt up internally so if i disconnected the battery and hooked it back up it show voltage but as soon as i tried to turn anything on it would drop to zero and nothing would work. i would try that since you have a relocation.

what do you mean "check your power wires"?

JPG ATTACHED; The black wire shown in the jpg is the wire from the battery to the engine bay fuse box. It feeds all the fuses in that box. The Main fuse can be out and all the other fuses still have power. Like your headlights will work etc.

So. THAT black wire should have power. And IF the main fuse is any good, the black wire on the OTHER side of the fuse box should have power. IF the front one has power and the one on the other side does not, then the main fuse is bad.

That wire on the aft side also goes directly to the large output wire on the alternator (and also to the ignition switch leads). Touch that large terminal and it should also have batt power if the Main fuse is good.

Don't know what else there is to say. Except the words on the jpg were for another post.

Thanks Hailers. I am not getting any voltage at that wire.

Is there any where else between the main fuse and the battery to check for voltage?

what i am saying is mine burnt up internally everything was hooked up right but the wires i used for some reason couldn't handle the amperage after a while everything worked fine for a good amount of time while i did my relocation then one day nothing couldn't figure it out. then i just decided to change my wires with taylor wires and no more problems

if the wire going from your battery to your fuse box can't handle the amperage i may not necessarily burn through the insulation but burn up internally and break the connection just like a fuse.

i have 0GA wires so i hope that didnt happen. I guess ill just have to cut the wire somewhere and see if its getting voltage in the middle. I was hoping there would be an easier way.

don't cut the wire just use the point on the volt meter to pierce the insulation. with 0g wire i doubt this is going to be your problem. but its a suggestion.

IF your talking about the wire shown in MY jpg, the answer is no. The battery positive cable should have two cables. The smaller goes directly to the BLACK wire shown in MY jpg.

It runs inside the cable connected to the batt, but *somewhere* in that harness it breaksout and goes to the place in my Jpg.

OR did you mean the black wire on the back side of the engine bay fuse box?

You said your headlights worked, so there has to be power on that black wire on the fwd side of the engine bay fuse box.

Fuse box installed 180* out?

Some part of me thinks the wire/cable from the batt is connected to the aft side of the engine bay fuse box and that is a problem MAYBE, maybe not.

I am not getting power to the black wire that goes to the main fuse as in the above picture.

My headlights do not work. Nothing works.

How about the black wire on the aft side of the engine bay fuse box?

On a stock car I'd say follow that wire back to the battery positive post where it combines with the Larger wire that goes to the starter. But you've moved the battery and I know not where the wires are routed.

well i think i found the problem... that wire going to the fuse block got twisted around my steering rack somehow up by the firewall and wasn't connected to anything. Also, one of the main grounds is getting really rusty, so i'm going to fix that as well. its too dark to get under the car and re-attach it right now but that's gotta be it. thanks for the help guys! ill try and wake up early and fix it before i go to work tomorrow.
