Hey guys Im having a problem find the negative side for my battery.A while back and its been a long while back I found to black wires with connections on them that either looked like they would fit the battery or body ground wires.The info i got at the time is they were body ground wires.So yesterday I put the battery in and i found the poistive terminal ok but I cant find anything that resembles the negative battery terminal.Im wondering if I have it bolted on the back of my engine block.Anyway someone can take a pic of the wiring harness so I can find the negitive battery terminals?I also found a small black wire thats been cut and in the front of the engine and have no idea what it is or where it goes.Any help greatly appreciated.
PS I read through 10 pages in the electrical and lighting section looking for help but notta.

 

Nevermind I`ll ask this the wire is a seperate ground that goes from the battery to the from or engine correct?

 

i have three wires on my neg terminal
thickest to the front of the pass side of block.
one to frame and one to rad core support.

 

As far as I know I only have 2 unless the two others I found a while back that bolted to the back of the engine are in the wrong place.warthogdriver would you mind taking a pic of what you got?Thanks

 

Ok I connected the wire to the frame and found the black wire that comes from the core support.I mounted on the frame by the engine.Is this correct?

 

i will take some pics later today for ya.
what you did sounds right. i would think biggest thing is having the engine ground and at least one frame ground.

 

[Thread Jack] does the big three ground go to the engine or core support? Use copper or steel lugs? [Thread unjack]

 

ok, here are some pics...hope they help

battery connection


block at front pass


frame near abs connector...pass side


i couldnt get the core support...it is below the battery tray.

 

Sorry I cant tell much by the pics but if the ground is bolted to the battery to the frame its a ground right?My wiring harness is such a mess I cant tell heads or tails of it.I have a diagram I down loaded so it should help.I`ll see if I can get some pics and uploaded tomorrow.Also in last post I mis spoke.The black wire coming from the core support I fastened it to the smaller black wire coming from the new ground cable I bought.

 

yes, in the battery pic it shows three wires on the neg connection.
thickest goes to the block, the two small ones go to the frame and one to the core support.
yes, the engine must be grounded. in my stang the block is just grounded directly to the frame by a grounding strap. as long as you have the ground with a good connection i dont think it matters where as long as its made.
