Hello

As the title really, I have to replace my alternator because I think at least one of the diodes has gone. I have seen various types of alternator about but just wanted to know what most people go for when its time for a change. I have seen high Amp versions like 65-70amp and just wondered if I should go for one of those?

I can get a replacement alternator for 45.00 + vat but get £13.50 back at the Motor Factors if I give them my old one for refurb but i guess that will be a standard unit thus lower Amp. Not sure about the brand at the Motor Factors but my car has a Valeo unit at the moment as I am running a metro 1.3 carb engine. I have seen 65 amp units unknown brand for £55.00 delivered on ebay.

Bascially just want some advice as to which to go for

Cheers

Rob

Well this one looks promising: -

But there's been some debate here on whether it will effect engine performance and whether it could overload the standard wiring loom?

91 car would have been 55 amp as standard. I have a 70 amp running on my 92 carb car, with no issues in regard to overloading the loom.

Well guess thats my answer

Cheers Simon and good old taffy again with the answers!

I will ask my motor factors what the amp is on their unit if its low I will get one of the high output ones

Cheers

Look just to make it clear...

Yes a 70amp will work (up to a point) without updating the loom - no doubt about it..


But: to get the *best* out of the big alternators. to give them an easier time.. . upgrade the loom...

note also that that the alt will only produce what the battery needs anyway... so if you arent running heavy ICE or fog lights then a 45 amp job will work the same as a 70 amp job..

My 90 Mainstream Cooper has an A/127 45 amp alternator.
