Wh1t, the starter battery is a Diehard Gold, purchased about 2 weeks after I bought the rig and I had every light on my dashboard going off. Luckily, I had frequented the Land Rover section and knew the probable root cause (touchy lr3's). I just went and got a battery which fixed all the problems. I Did not do the voltmeter yet but purchased all the wiring to do 2 runs to remote blue sea fuse boxes, 1 in front and 1 in the rear. Volt meter will tie into front one and that will be a easy install once I've breached th firewall and set up remote boxes.
Btw: planning on using 5025 boxes and 6awg wiring. That allows a lot of capacity. Rather spend a little more and then never need to redo it later.
