Hi guys.
I'm after a new alternator for my 1.8si cabriolet as on full load (lights heated screen and stereo on) it can only put out about 11.4v's. so my question whats the highest amp alternator that will fit it ? , and if not a escort one what car does it come from so i know which one to quote when ordering it, as while I'm changing it i might aswell upgrade it ready for the stereo upgrades i have planned.
cheers

Are you sure the alternator just isnt faulty mate

You will need a high output, the heated screen draws massive current, I assume you added this?

80A I would say you need, a Mondeo one would fit, as I guess yours has the same "Zetec-E engine".

why don't you use one off a diesel escort they have a much higher voltage done this many times over the years and always works with no problems

Amperage, not voltage

OP, you need to establish what one you already have, with that screen you will want one sutiable, the Escort Diesel (70A, IIRC?) may not be suffice.

update on this went for the 90a non power steering alternator which fitted fine only difference was the wiring layout was slightly different.
