hie guys just a quick one.... what are the implications of fitting a higher amp rated alternator? i mean like fitting a 120 amp alternator marked for a 2.5 v6 on a 2.2 CD which originally had a 70 amp unit

thanks in advance

Not a conversion I am familiar with, but Physical shape and size and connections are the only things I would want to check.

I do not see that the increased output would cause any concern.

thanks Dave
im thinkin of upgrading the alternator reason being if i have the rear demister on as well as the headlights coupled with the heated seats my battery light on the dash comes on but very faintly(Only noticed it by chance). on second thoughts should i replace the battery instead?

The fact you light comes on under high load suggests you have problems with your existing alternator, the standard alternator should be capable of keeping up. I can't see you should have problems by putting a bigger alternator on though.

might be worth going throu the electrical checks as in the maintenance guide to find the real fault.

Voltage regulator playing up. See guide for replacing
