I've had an intermittent dull glow from the charging light on the dash recently which strangely seemed worse at higher revs. Anyway out in the dark and rain 50 miles from home yesterday evening it was glowing like a good 'un so might be time to swap the alternator. I have an old spare but, as Christmas is coming (so I've heard), I thought I might treat the old girl to a new one! However there's lots of output ratings available 35A, 45A, 55A even 75A. Any thoughts on the best one to go for?
It's for the 2.0 with a couple of extras like electric fan and fog lights.

Re: Alternator rating
Standard is a 45amp but with the extras it can't hurt going to a 55amp so long as your battery is also up to it. My Laser has an 097 battery with a 54 amp rating.

I think the 35 amp alternator would have only suited a 1.6 base with no heated rear window or rear wash/wipe and other electrical toys.

I 'borrowed' a battery from the 2.8 a couple of years back so 55A sounds the way to go.

Re: Alternator rating
Hi Peter, I got a 55A one too on my Pinto as a couple of years back I remember I was deciding between either the 45a or 55a and decided to go 'up' as I have Bosch battery at a higher rating than standard.Peter-S wrote:I 'borrowed' a battery from the 2.8 a couple of years back so 55A sounds the way to go.

Almost surprised that the old girl started this morning so I guess the old alternator must be doing something but a shiny new one is on the way

Re: Alternator rating
I remember in the late 80s the alternator went on the 1.6L I had and I replaced it with a 2nd hand one from a Mk2 Granada Ghia. It was a much larger unit but the mounting points were the same so I just swapped over the pulley. It charged the battery better and coped with all the electrics on at the same time without dimming the lights. For the minimal extra weight I'd recommend increasing alternator size rather than a like for like replacement.

Re: Alternator rating
55a is fine for what you require there Peter.
