Hey guys,
as a bettery tech I would recomend against running 2 batteries paralleled together but by all means go to a 4WD shop and get a quote on a dual battery system. They should be about $200au but this will let you monitor both batteries and you can isolate them as well. Why isolate them? If you stereo battery dies or goes flat you can still start your engine. Once your engine has started you can then switch to charge your secondary battery. On the off chance both batteries are as low as about 20% there is a button you push while cranking your engine and this will parallel both batteries together so you can get home. The duel battery system will automatically charge your primary battery 1st then your secondary. These are great systems and worth the $.
On anouther note if your system seems fine, and everything tests ok, have a look at your harmonic ballancer. I didn't realise that on most cars these are 2 pieces joined by a rubber spacer. When the spacer perishes your ballancer will spin inside you crank pulley. I have recently welded mine while I waite for a replacement and my head lights are brighter, power windows go up faster, and the power steering is lighter. The ballancer is really easy to get to from the drivers (for right hand drive) wheel arch. just take off the splash gard and there it is. Get a good hold of it and try wobble it. If it moves take it off (it's only 6 bolts) and inspct the rubber, Preferably from the engine side as this side will perish faster. I can't give you a price yet as most of the shops in townsville here say " What the hell is an MX-6" or "don't you mean MX-5". But we are educating them slowly.
As for altinators have a look at running 2. 1 for each circuit, but realistically go the DBS, it's smaller, possiblycheaper and I know it works.
Hope this helps.
