Simple Q: Reconnected battery wrong but not sure where. (2 Viewers)

[rc51kid]

I'm a total noobie to the world of wrenching so I apologize if this is a stupid question. I pulled the battery and put it back in today, but now the truck won't start. I get aircon and lights but no ignition. I realize I should have just taken a picture of the battery before I began.

Here's the battery "reconnected". What did I do wrong?

Just noticed you pos lead clamp doesnt have a nut on the clamp. You cant at all get a good contact without it being tight. A poor conection will give power to the system. But the minute you try to pull any real current like starting the truck itwont do it. The same thing will hapen with bad grounds like we talked about.

With a bad conection it will act kind of like a weak batt, power but then just a "click" when you turn the key or nothing.

Not saying my s*** is perfect. I have a ratty old truck with 358,XXX miles on it. But here is a picture to give you an idea of what size and quality battery cables you would want. This is my Aux batt so it has fewer wires going to it but you get any idea. What i have is probably overkill but i sleep better at night.

Also you might notice my batt is backwards. I did that intentional. I wanted the Pos mounted to the inside and i wanted to run two of the same 27 batt in both sides. Not a 27 and a 27F. But just my way of doing it. More than one way to skin a cat.

The "empty hole" (crossed out in pic) on the ground terminal is designed to have the main chassis ground wire crimped in to it, but it appears that there still is a large, thick main chassis ground (circled in pic) that just goes to the bolt on the terminal instead of the empty hole.

Make sure that chassis ground is securely attached to the frame or chassis (i think it's below the A/C compressor on my 91) and that your positive side thickest cable (the one going to the starter) is securely fastened to the starter and not damaged. If you have no power at all, like no lights or horn or dome lights, check that your fusible link is still attached. It's a small black box with two ring terminals in it and a standard plastic connector (make sure that connector is connected) that's supposed to be attached to the positive post on the battery. If the fusible link isnt attached or faulty, you'll have no power. Wouldnt be bad to replace it anyways. I think @NLXTACY sells new ones. They look like this.

Does the 3F-E even have the same fusible links?

That's what they look like on my 3FE. OP's truck is also a 3FE.

Edit for clarity: the pic i attached in my original response is what they look like on my 3FE. Idk what 77mustard40 posted

The 3FE in an FJ80 uses the same links as the FZJ80. what @77mustard40 posted is a fusible link from an FJ62.
