Dymamos/Alternator

[Rosanne]

I was told recently that older cars (I.e 50 years or more) may have alternators that are unable to put any charge into the car battery, whilst the engine is just ticking over and that the engine has to be running at higher revs in order to do this.

Is this correct?

Thanks for your helpful replies. The car in question is a 1960 Ford Anglia 105 e which was converted from positive to negative earth at some stage. It also had its Dynamo replaced with an alternator, but I don't know when.

Could the fitting of a modern type of alternator improve things re battery charging ?
