Moving battery to boot

[anonymous-user]

Part way through moving the battery to the boot and have run the live lead down the inner sill and into the boot all well.

Before I do the negative one, what does the negative lead in the foot well connect to ? Is it onto the chassis or into the loom. If it just goes to the chassis I need not bother and I can find an earth from the boot ...

Many thanks

David

Where did it go when it was at the front?
I'd say you could go to chassis but I'm not a TVR owner so it might be wrong.

Having a bit of a problem with a leaky heater dripping over the fuse box and thinking of moving the electrics away from there how have you done it and was it easy?

When I did mine I took an earth cable down behind the fuel tank and out of the fuel pipe hole then earthed to a convinient place on the chassis. Can't recall exactly where but was a flat section part rather than a tube, clean to bare metal for good contact then re-painted when cable attached.

Thanks, does that mean you did not extend the cable in the foot well at all ?

Thanks

Think the original battery earth cable on mine went to the body mounting bolt under the front of the centre console ? I dis-carded it but did clean up and secure all the other earths that are there.

On mine the earth from the batt went to the body mount up on the transmission tunnel along with a lot of loom earths. While I had the whole dash out fitting a new body loom I cleaned up all the earth points then sealed the terminals with a coat of silicone grease to try to stop further problems.

If your putting the batt in the boot then you would want to run a new heavy duty cable from the batt to chassis trying to keep the lead as short as you can.

Hi All

Just about to move my battery to the boot. Is there any reason why I wouldn't want to put the battery in the middle of the boot, just above the fuel tank. I'm going to make a battery tray over the next couple of days and bolt it through the rear bulk head. I'm using one of the smaller race batteries to save weight and space.

Cheers

Mine is going in the middle too, still gives room to get the roof in.

All done, cables extended down sill with 3m lengths of 25mm sq new cables joined with a cable joiner, all heatshrinked and then wrapped in plastic hose. Battery in centre of boot floor for now, so I can get the roof in and out easily.
ECU and assorted gubbins, on a wood plate I made and fixed to bulkhead with bolts on rubber blocks.

Just went for a 20 min test drive and car goes great, must be not using it for last three weeks that makes it go so well. Lots of nice cars out this afternoon by the way.

Added bonus at least 6'' more passenger foot room.

Hi David, when you say "cable joiner" what did you use ? I may have been tempted to go 35mm or even 50mm given the extra length.

I used a brass sleeve with four grub screws, and I filled it with solder in addition. All parts came from a company called vehicle wiring products, that I have used for many years when building kit cars, they are really excellent by the way ( not connected)

You are welcome to use heavier cable if you do yours by the way..........

I'm about to use 40mm cable as advised here-

My car has 20mm square on it as original and I have gone to 25mm square.
It works fine, car turns over same speed and starts as it did before .

Thanks David, sounds like a good job, it's on the to do list !

[SILICONE KID]

Can you see the cable behind the carpet..

[anonymous-user]

Only if you are behind the carpet..........

No actually you can't , there is a ledge on the inner sill, I taped them up on here before I re did the carpet and it can't be seen

Hi David

What did you do with the other cable to goes directly to the battery (brown in colour), did you extend this one to reach the new battery position as it sounds like you have left the ECU etc in the footwell? What cables and connectors did you use?

Cheers

Hi
I used two lenghts of 25mm sq battery cable and a pair of 'but' connectors( brass tubes with 4 grub screws in each from a company called Vehicle Wiring Products

Both cables full lenght along the inside sill of the car.

Moved my battery to the boot recently. I used the left side of the boot, first laminating a wooden board in to create a flat surface. Used a polypropylene battery box from a ship chandler with a lid and strapped the complete contraption to the wooden board. The filt innerliner of the boot can be used to cover it all up. Looks good and was approved in the APK (Your MOT). The roof still fits easy. Used two 40 mm2 leads to connect to the original leads. I used the footwell battery box to make the connection pionts by removing most of the box sides except for the backpart. That way you can fit everything nice and secure and still have room for the ECU. I'm 1.90 mtr but have more than enough room to stretch my legs (not being at that side of the car much, though...prefer the fun side).
