what aftermarket ones are close to a direct bolt on?

im running 3 batts, a twin motor hi-mount, fridge, driving llights and stereo and the stock one doesnt seem to be keeping up too well

I reckon Hitachi are good, you may just need higher output, what's yours about 90 to 100 amp?

Yours is a later model so it has no integral vacuum pump so that opens your options right up. :)

I'd just pull yours off and take it into Deerings or the like and get them to match up a higher output one.

don't disregard Hitachi though, they seal them up really well in comparrison to some and i just pulled one out of my GU ute last year that finally died after 350,000kms of dust mud and water, bloody brilliant i reckon :armsup:

is there such a thing as too high output? If i'm changing, i'd want to go a big as possible like 350amp or so.

That way she'd never die even with everything running... like winching a steep climb at night with all lights a-blaze and the fridge in the back!

umm as far as I know there is such thing as too high. Something to do with boiling batteries or something. Please don't qoute me, can't remember the exact details
