All 3 batteries are now installed and charging etc, they are all isolated from each other :D , however if anyone else plans to do this 1 problem that did arise is that having 2 split charge relays being "tripped" or activated by the alternator isn`t ideal as the current draw for the 2 relays is a bit to much for the alternator and when starting the engine I had to rev it up to about 4500 rpm before the alternator would "kick in" and start charging, so to overcome this I have added another relay :roll: which is tripped/activated by the alternator....this additional relay then activates the 2 split charge relays, and so now all works well and when engine is started a quick rev to about 1200 rpm and alternator starts charging all 3 batteries........ if anyone else wants to do it this way and wants a wiring diagram or assistance, just let me know :D

Hey Leeday, I know this post is getting on a bit now but is there any chance I might be able to take you up on that offer of a wiring diagram? :)
Cheers,
