That's not good... :( Looks like a fair bit of research is going to be required then...

And does anyone know the max you could fit to a B? :)

	Ya reckon? If so, furry muff :) You know what I'm gonna ask next though... :thumbs:
Richie	posted on 13th Nov 03 at 20:02
	Trotty, just get a 70a one and get it uprated, will work out much cheaper.
Trotty	posted on 13th Nov 03 at 20:00
	I've got a 1.2 as well, just trying to fudge a bigger one on from a higher model :) AFAIK one from one of the higher end diesels should be ideal, just need to know if it'll fit or not... :boggle:

Sorry to nick the thread, anyone know whats the max size alt i can get for a 1.2? Just want to replace it even before i start wacking amps in my car :) (sorry about the hijack) [Edited on 13-11-2003 by VisibleMan]

	where is the alternator how much are they and what does it do??
Richie	posted on 13th Nov 03 at 14:31
	Your gonna want one with around a 70a output or higher. Dave, if you dont get a better alternator ect the second battery will never get a decent charge anyway.
Dave_Gordon	posted on 13th Nov 03 at 14:17
	Why dont you get one of those optima batterys for your boot should do the job nicely!!!!!!!! easier wiring for amp aswell!!!

	:look: :(
Trotty	posted on 10th Nov 03 at 14:50
	Ah righty, okey doke peeps, thanks for the help. Time to look into getting a better alternator then. You think one from a 1.8 or the 1.7d would be a suitable choice?
TOMAS	posted on 7th Nov 03 at 17:37
	Yes cap is always last. Without the alternator their would be NO power in the first place! Bigger batteries always seem to show as a good result as they have a higher capacity and dont flatten as quick but often wont last that long, well not as long as if they had a GOOD altenator charging them :thumbs:

	i woulld have thought u'd upgrade the battery and alternator before u start considering a cap?
Richie	posted on 7th Nov 03 at 15:13
	Well in most cases try and upgrade the standard battery too, get a diesel battery. My Exide one has 650CCA's and helped greatly powering the headunit, fogs ect. Was only £27.99, defo worth it. Upgrading the alternator is indeed the first thing. It supplies much more power than a battery, much quicker.
Trotty	posted on 7th Nov 03 at 15:01
	m-dot - I read it last night! :P Just forgot to reply to your U2U... :( TOMAS - ah ok, so you'd recommend a better altenator before changing the std battery?
TOMAS	posted on 7th Nov 03 at 10:01
	Bigger altenator first (if possible) and then upgrade to a bigger battery OR split charge with another battery (sealed jelly battery) in the boot :thumbs:

	I get dimming lights aswell :( Read your emails you cunt :mad:
Trotty	posted on 7th Nov 03 at 08:58
	Erm, actually, no I haven't :( Running a single JL 500/1 at the moment, and 2 JL 12" W3V2-D2's I've got a Directed 1.2 farad power cap but even with that, I'm still getting dimming lights on big drops. Is this down to needing a bigger cap, or a meatier battery in the first place? If so, recommendations.. ;) Optima Red Top? That Exide jobby? Also, if I do change the battery, is it worth changing the alternator too? Ta in advance folks :)
