Biff, did you get lost today?  I waited til noon and you didn't show up!!  crack

So anyways, after biff didnt show up I had to tackle it on my own.  After much sweat, tears and blood, I finally got the *beeping* *beep* of a *beepin* *beep* *beep* out from under her belly.  The weather decided to help by lucubrating proceedings.  Now need to pick more brains.

What is this loop of pipes for?  There is one left and right in the centre of the battery?

It could well be the battery top up system as mentioned in your link on the previous page.

"The first vehicles required these to be removed to allow them to be topped up with distilled water but this was a long and laborious job so Chloride invented the centralized watering system known as Autofil"

Yes, I guess thats what the 3 auto fillers and pipework is for but what are the two extra white things for?

If your van needs a new controller then check this out. It's only a 500 page thread but a fine read.
http://ecomodder.com/forum/showthread.php/paul-sabrinas-cheap-diy-144v-motor-controller-6404.html

The only trouble is it will probably take as much time to read that thread as it will to weld that van of yours back to MOT standard.  hysteria

I am pretty sure somebody will be interested in the electrical gubbins in your van. It would be nice to see at least some of it recycled in some way rather than scrapped.

There's not much of the electrics any good.  I think a bird has tried nesting in it!!  The back axle and DC motor would probably be useful to someone thought or some of the internal controls, knobs and buttons!

Yes it would.  I've found two problems and they both with the battery.  One was that a pole on one of the batteries was damaged, the other was there is a fuse at the back of the battery bank has been damaged too.  Once I sorted these I got a voltage of 4v across the 216v bank!  I have two cut out and on pulse charging at the moment, they seem to be holding the charge ok and maxing out the trickle charger.

Anyone any ideas how to remove the battery connections, I've tried a blow torch to melt the solder but its damaging the battery.  There must be a better way!

The only way I can get the batteries out is to cut the interconnections. They seem to be manufactured like this.  Unfortunately the cable tails are too short to reconnect in a tidy way.

I've cut off the insulation and seals from around the terminals (see photo), but now I need a nice tidy and electrically sound way to connect them up again in their new home.  Anyone got any ideas?

Hi Clive,
         You can use a hole saw and drill down vertically from the top leaving a nice round pole that will take the ordinary battery connector,
       the hole saw is a hollow drill like a hacksaw blade and you can have different pole sizes for N  and P.
      You best do it while the batts are flat.

emmm I dont think I could !!  How do I keep it drilling vertical, wouldn't I need a bench and rig/jig or something?  This is the part of engineering were I fail!

Its simple enough Clive.
                       Just pick the diameter of the pole you want and choose the hole saw to match,The hole saw has a little pilot bit inside and the lead is soft.It will only take a few minutes with each one useing a good cordless and a steady hand.
       You could try it out on one of the dud batts to get the hang of it.

What diameter are the terminal poles? You could hacksaw off the angled tails and with a few strokes with a rough file be left with nice round poles that may accept the standard positive or negative pole terminal. The posts are normally tapered but the connections may deform enough to create a suitable contact area depending on design.
Careful use of a marker pen to mark the battery's positive and negative terminals to avoid confusion at a later date may be prudent.

Hey camilitech, I'm checking out your Funk D'void (Original Disc Jockey & purveyor of the Luxury Techno sound) flyer in the back ground. Are you guilty of chucking shapes or dad dancing in the past?

I would have thought Gary Numan with his Are Friends Electric track would be more applicable to this battery derived thread.  hysteria
