Alternator Identification

[Dougal]

About 5 years ago our alternator was replaced and I've lost all the paperwork. I can see no markings on it at all Might there be a way to identify it, or is likely to be some poor generic thing?

It will probably have identification on it somewhere, although you may need to remove the alternator to see it.

You could post a photo of it, and someone might suggest what it is.

I recently had the same problem, but the identification plate was on the engine side and could only be seen once the alternator was off. That applied to both Lucas and Prestolec alternators! Not very convenient!

If there is nothing wrong with it then why do you want to know
If it is playing up then take it to a repairer and they will sort ot in a couple of days.
When my one on my volvo went i took it to a repairer and he told me the manufacturer in seconds
£ 110-00 for new bearings, regulator , new studs for connections etc
Many marine engine alternators are just auto ones so i am lead to believe

THAT is exactly why i want to know;-)

The Adverc installation instructs have some useful pictures of different makes of alternator and can be downloaded from http://www.adverc.co.uk/cm/files/pdf/Adverc_installation_basic.pdf

Give us a clue, something like a picture may help.

Every yacht should have one

I do, but I am not sure there is much point, since my alternator is regulated to 14.4V anyway. The Adverc can only ever do anything when temperature compensation gets that below 14.2V.

the Adverc actually senses the battery voltage & adjusts the charge to suit what it ( the battery ) can accept

It cannot reduce the alternator output, only increase it, and it won't increase it above 14.2V.

It can & does ramp up the amps if the battery can accept that level of charge. I have seen 40 amps going in

There are all i can get for now...

I have a copy of the Alternator handbook on my website under downloads. It gives info for identification.

That looks great, only it's dated 1986!!!!! Surely they've changed a little since then?

I think it is an Iskra. Something like this:

They are called Letrika now, I believe.

Indeed it can, but only by raising the alternator voltage to 14.2V maximum. If the alternator's internal regulator already produces more than that, and many modern ones do, then the Adverc does absolutely nothing at all.
