Thanks for all the replies to my question about TD 100 cruser a few days ago.
My mate is going t install a 950 cold cranking amp battery as the cranker but before setting up the whole system we need to know what the cables are that come off the positive side of the drivers side battery, will we need to divert them back to the cranking side.
Again thanks for your thorts and feed back..

Yes, you have to move them to the new 950CCA Cranker battery, what they are is not relevant, as they will NOT be used on a Deep Cycle battery, because Toyota had them originally connected to a Cranking battery.

The cranking battery will be the passenger side one and all you need to divert is the feed wire from the alternator with some 6 b&s cable from where it joins the drivers side battery across to the other battery.
You then remove the heavy wire connecting the two positives and put your isolator on the inner guard just behind pass battery. Run no 1 to that battery and no2 to the drivers side one. All your accessories then come off the driver side battery
A N70 is heavy enough to crank it anyway and its best to have two similar capacity batteries as well. or you may well have duelling batteries instead of Dual batteries

Yes it is on the passengers side but the alternator feed is on the drivers side hence the need to extend it to the other side.

If its still standard they are both linked anyway and it doesnt become the ONLY cranking battery till u split them

I watched my mechanic fit a Redarc battery isolator when instead of routing cables all of the engine bay he simply terminates a length of cable with a lug and connects it to the rear of the alternator for the positive of the second battery. If you have a look at the REDARC www site you wil see the wiring diagram/fitting instructions.
