Just as an FYI I've searched and there is nothing this vague on this topic so I'll create it. My battery terminals have seen better days espicially the one closest to the front of the car so it's time to replace them. I'd like to replace them with OEM terminals but I'm thinking that the terminals are not sold seperately so I'd be interested in what many of you have done to replace your terminals. I'd like to keep the OEM look if possible.

thanks

 

That's a good question! I dug through the parts diagram - you can buy the whole positive terminal assembly with the fuse block and fuse block cover. Part is FD02-66-760C, and it's about $60 - I think it may even come with new fuses.

Haven't found the negative terminal - I think it's considered part of the starting/charging harness, which is well over $500 - eek!

The negative will be trickier, definitely. There may be an OEM-style crimp-on connector out there, but you'll have to dig.

I think I found the negative battery terminal

I moved my battery to the back many years ago so have newer terminals, but this is definitely a useful thread for owners with the original terminals still in place .

 

Is there any place to order just the positive terminal connection? Mine is cracked in the part around the actual battery terminal, and I'm certain its days are numbered. Hopefully enough detail can be seen in this picture.

 

I bought a positive terminal from walmart. It connects to the fuse box using a wing nut just like the stock one and even looks stock. Walmart sells them for ~3 dollars if I remember correctly.

 

Aces! I'm heading that way in a few minutes, I'll check there.

Honestly, Walmart is the last place I think of for FD parts most of the time.

 

Wal-mart is alright. Try Autozone or whatnot.

 

I just ordered the part that Dale Spoke of for the positive terminal, and I have the negative terminal coming in from the company I posted the link for. Now all I have to figure out is what type of crimper I need to use to crimp the new terminal.

 

it's shown on the parts diagram but i ordered that part number and unfortunately it didn't come with the +ve terminal.

 

I just received mine from Malloy and it came with the positive terminal.

 

I'm coming back to this thread because this was the best lead I found on getting and OEM-like negative battery terminal, and I want to close the loop for anyone going down a similar path.

The Del City link above no longer works, but you can still purchase a negative terminal from them. It's called a "lead-free OEM style terminal", and true to the name, it's the same style as the OEM Mazda terminal, but not an exact match. The part number I purchased was 909095.

Here's how it looks on the website:


You need a specific tool to crimp open-barrel terminals. The proper crimper puts a sort of "B" shape into the terminal. I went with the Sargent Tools 6225 CT. It costs about $150.

And here's how it looks on the car:

 

I'm not a big fan of these cheap parts store terminals as they are made of thin metal that easily bends and often the fastening mechanism loses effectiveness over time. I bought these for my Z32 and was very happy with them:

 

That looks great!

BIG question - does it use a 10mm wrench on the nut or is it a weird size?

Mine is in so-so shape but I'd love to have a new looking one.

For the positive terminal, it’s OEM...just not Mazda —->

It uses a 10 mm socket. I'm happy with the results.

 

I had the same problem and used an RX-8 terminal. It's pretty damn close to the original. Part #F151-67-TB1, $24 from Atkins.
