Rear Battery Box Conversion

Since Photobucket hosed my pics, I have wanted to redo my thread, but haven't been able to edit the original, and repost the pics. I think that the best method will be to just create a new thread. It will take me a while, so please don't post any comments, until I get it completed.

This is the link to the old thread, in case you want to look at it:

Re: Rear Battery Box Conversion

When I finally decided to relocate the battery, to the rear of my Laser, I couldn't find much info on how to do the entire conversion, so I decided to post this here. I'll eventually post the parts and price list. I'm sure there are better ways to do the conversion, but at least this will show one method.

My car is an '86 Laser, but a lot of the hatchbacks should be pretty close. I wanted to mount it passenger rear, to move weight to the opposite side, but the wheel well doesn't leave enough room. There is just enough room on the driver's side, so that's where I put it. I used the Morosso box, but did not buy the complete kit, because I went with a longer ground cable. If I did it again, I would just get the kit, with the short black cable.

The last pic shows the amount of space you gain, which works great as a cool air box.

Re: Rear Battery Box Conversion

The first pic shows how I mounted the terminals, near where the old battery was located. This allows you to keep the original wiring pretty much unmodified. My wiring is heavily modified, because I converted the fusible links over to the Power Distribution box.

The 2nd shows how the inside of the box looks, with the battery in it.

Re: Rear Battery Box Conversion

This is where I mounted the box.

This is how the hold down clamp mounts.

I added a bar underneath, to fill in the groove in the deck.

The cables are routed through the sides, using grommets.

Re: Rear Battery Box Conversion

I had to find a good place to mount the ground cable. I decided to drill a hole through the frame, just in front of the driver's side rear spring mount.

I used a piece of threaded rod and put nuts on both sides.

Re: Rear Battery Box Conversion

I decided to mount the cutoff switch above the battery.

I made a box for it.

A short positive cable mounts on the inside.

Re: Rear Battery Box Conversion

One of the hardest jobs was finding a place to route the positive cable through the firewall.

I decided to make the hole next to the hood release cable, using a drill and knockout cutter.

This pic shows the tool and cable pass through that the cable will connect to.

On the engine side, it comes out below the brake booster.

This is the engine side. A nut will lock it down.

When you route the cable, make sure that it will not chafe on anything.

This brings up another issue. Some of you may have noticed that if the cable shorts, it could be disastrous. I will cover adding a circuit breaker, to prevent a short from doing damage.
