thread I was only planning on running stuff
(other than internal lights) with the engine on, or when we're hooked up to mains.

Do I still need a beefier alternator?
sam at cowjam.net if you want to give me some idiot proof advice :)
permalink an alternator will only charge when the engine
is revving, I'll sort out some details for you in the morning when I'm a little less monged ;o)
permalink cheers
