It is most unlikely that such an alternator change will materially affect your charging time. Increasing the charge voltage however will. The existing unit together with an alternator controller (or adjustment of the regulator setting) would be a better option. IMHO the only justification for such large alternators is where large loads are imposed whilst running. Typically the use of an inverter for vacuuming, or cooking. The above assumes that you have a twin alternator setup with NO diodes in the system. Infact if you do have a twin setup then incorporate a system to link the alternators. Take a look at www.smartgauge.co.uk for alternator control and linking. > >I have read that fitting such a big alt. could/ would damage the batteries and >other advice says that it would not. > It should not. >Any advice as to advisability or not would be appreciated. > >Richard Tanner >NB Cartref The above advise is worth what you paid for it! -- Richard
