Club 80-90 Forums

Hi All
How do I tell which alternator I have on my van? Ropey bearings, and it'll either be a new alternator or maybe replace the bearings...

So how I know if it's 65A or 90A? Best place to look for part no?

Thanks in advance...

There is usually a sticker on it,the info you want is on there.

assuming it's origional Bosch, and assuming petrol and diesel look alike, the 65 and 90 look different 90A on the left

Thanks both for those quick replies, I'm hoping for a sticker but the difference in the end plates is a clear giveaway.

in my experience stickers are usually long gone or illegible

If you are stll unsure get a pic up.

In that case,sorry for trying to help.

Just my experience, yours is different, no right no wrong, no need to get upset

Im not upset.I was just going off the two i have here.Maybe im lucky that both of mine can still be read.

As I said your experience is different.
I have never been that lucky.

TBH.Lately im thinking if i didn't have bad luck,i would have no luck at all.

Gentlemen, you are both helpful, and have been for many years to many people.

I didn't find a sticker, but the backplate is clearly 65A. I didn't take the alternator off as slipping the belt off revealed that the bearing is spinning smoothly, a trace of lateral play but about 0.5 mm of fore-and-aft play, which is what I had first noticed on a cursory look-over. The water pump is also smooth, and no play.

So I shall resume my watchful waiting...

Why do you think you need a 90A?
unless you have fitted lots of extras a 65A will be fine.

I thought the 90A one made your van go faster

Only if you are lucky

Yes that desirable "upgrade" has always amused me.
45 amps is more than enough for these old ladies electricals.
