1980 CJ7 battery questions

What side of the battery are the positive and negative posts when looking at the battery holder? Also, where does the negative cable ground to?

The negative is generally on the right side depending on the battery. You can tell because the negative terminal is smaller in diameter than the positive terminal. The negative cable connects to the engine block on the passenger side. There is a bolt hole specifically for it

Stock battery was a "Group 24". Assuming that if you are looking at the battery from the FRONT, the posts would be at the rear corners, Positive would be on the right and Negative on the Left.

There is also a Group 24F (for Ford) where the terminals are reversed. Looking at the battery the same way as above, Positive is on the left.

If you wound up with the wrong "24", flipping the battery around would put the terminals where they belong, but the cables might not reach. Sometimes they do, sometimes they don't...

There are other battery groups that will fit, but the one called out for was Group 24, the good old standard work horse of the day for trucks. The other battery might have the same width & depth, but might not be as tall or could be taller.

I put a dual battery tray in my Jeep. There's a 24 & a 24F hooked up in [s]series[/s] parallel. That way the cables are shorter to connect them. In the picture below as you view it, the 24 is on the left and the 24F is on the right.



Because the terminals are reversed the 24F, they line up with the same poles right next to each other making for shorter cables.

I should have added that the previous owner had two black cables. What I was looking for was something maybe original. Also, I have the 4 cylinder Iron Duke motor. And, on the ground cable is there a small black wire coming off of the ground, and if so, where does it bolt on?

How has that battery setup served you and is that an aftermarket tray?
Thanks

Hopefully they are in parallel, not in series.

WHOOPS! You're right! It would explain the smoke though...

Home built based on the factory. I just "grew" the dimensions, flipped it 90º, used angle iron and the floor is expanded steel plate. Factory supports. Works great, been in place for years. I doubled up on the batteries for the winch. sometimes you can't winch and run the motor at the same time.

This is a frame up restoration. Previous owners probably did what they had to do keeping the Jeep going. It ran when I bought the Jeep, but it needed work. Being retired, this was a good project. I'd like to restore as close to originality as possible, but am willing to do what is necessary to get it going. Thanks for your imput.

For reference, this appears to be a fairly unmolested Iron Duke in a CJ.

Hope this helps,

Matt

Thanks. I like the dual battery setup.
