My conversion looks as though it'll need the battery elsewhere, not sure what the rules are for the mot, my mrs's old ex mil landy had 2 batterys under the centre seat, would it be acceptable to the examiner if I were to stick the batery under the drivers seat, would I need ventilation?, I have a load of bits left from a rover 218D trike project, one piece of which is the battery tray, I was thinking of welding this to a bracket on the chassis.
Then going to mi welding supplies place and getting them to crimp a couple of lugs onto a length of 50mm2 earth cable and connect this up to the series solenoid which I'm planning to leave in and just use it as a terminal block, and lead t'other end to the battery with a few p clips holding it secure.

Under the passenger seat is more normal, after all that is where they are as standard on 90s & 110s.
 
Cant see it being a problem for MOT. The only thing they ask for is that the battery is securly clamped into position and wont move about. Another thing is that the terminals are not going to come into contact with any metal objects that would cause a short between the terminals........
 
moved mine under the passenger seat but had to buy a smaller batteries to fit and i used the 200 tdi wiering loom as reach`s and just made a new earth lead to go from the batterie to the gear box, ill get you a pic if you want one
 
My experience of Land Rovers, as distinct from any electrical knowledge, would say earth to the chassis.
 
manufacturers earth to the chassis and thats probably for a reason, however the starter is on the engine, and an earth direct would be a lower resistance connection and less places for corrosion to ruin things.
Must be another reason.
 
Not on a Land Rover!
I think it is something to do with the material the flywheel housing is made of. I've seen it many times when the earth lead from the stater bolt to the chassis had got missed off, even if they had put an earth directly from a head bolt to the battery.
When I was a delivery driver we had standing instructions to check that if there was ever a warrenty claim about a starter, and we were virtually allways right. Made us wonder if they needed to replace their original starter in the first place!
 
Incidentally, you obviously know a bit about vehicles, but wisely joined a Land Rover forum, then when 3 experienced LR owners give you some advise, one quite strongly, you think you know better!
 
Apologies to anyone else's toes I stepped on, but Dave, if your gonna say anything, advise me not critcise me, this is the third time now.

I know very little about very little.
 
Dave I'm not arguing, find someone else to winge at.

Ian notts, you were right not to earth the 'box, I wasnt going to earth at the box, more the bellhousing, even so the issue is, spose the bellhousing to engine electrical connection were to fail which is unlikely but possible, then the return current path for the starter would go the other way down the prop shaft, possibly welding the needle rollers, and through the diff/suspension if the rubbers are not in great condition, not an ideal situation, the chassis earth should it fail would just make you a dead duck.
