Just to clarify this is what I mean- Image

I haven't done it in the engine bay but same principal- and you can treat the stud as an extended battery terminal if you like!- Just make sure that both studs on the bobbin aren't connected somehow before you wire it up!

With starter cable I just use the biggest I can find, less voltage drop then and won't get hot if you have to keep cranking or jump start- I think my jump leads are 40mmsq which is fairly big, and my starter cable on my landy is about the same.

Ah just managed to get a bad picture!
Image

ps those cables do not include my starter cable- but no reason why you couldn't do it so long as you make a good connection!

Can a 24v alternator be used to charge a pair of bats in series, and then take a feed off the split between the batteries to pick up 12v??? Im probably talking gonads, but its just an idea,

Hi Ian
yes you can, only two things to be carfull of
1/ use good condition batteries, if a cell goes short cct you could boil the rest of the battery
2/ if you fully dicaharge a battery don't charge the pair up off the alternator as the other will see 24 volts and big amps, it will boil and go pop (with the interesting effects of boiling sulphuric acid can have on your day, I saw this on a UPS battery once and it was a bit untidy to say the least :lol: :lol: :shock:
If you are using the two batteries to drive isolated CCTs you should have no problems but I would have a volt meter across each in the dash so you can check them before you hit the starter.
