[Amel Yacht Owners] Alternator pulley

Bill & Judy Rouse <yahoogroups@...>
 

Paul,

Did the supplier assure you that the alternator is an isolated ground alternator?

What is the country of origin? If China, forget about it...in my opinion.

The pulley size is critical because RPMs for your motor RPM gauge come from the engine's 12VDC alternator.

Hi, I am about to buy a non-genuine 12v alternator for Volvo D3-110i-C (Amel 54). The supplier has advised me this:

The alternator is 50Amp and is identical in every other way, you will however have to exchange your pulley from your old alternator to the new alternator in order for it to have the correct rotation speed as the volvo alternators also drive the tachometer reading and the pUlley speed is critical for an accurate reading. So the pulley must match your engine. The genuine volvo alternator would also need your pulley exchanging as they also do not come with the correct pulley fitted.


Does anyone have any experience of this? I am very surprised that a replacement alternator, even a genuine Volvo one, comes with the wrong pulley wheel attached!

Cheers,
Paul

The Alternator is a Valdo from Turkey (60A 24v), it was on the boat when we bought hear, I assume it's the original one as the 12 v alternator also is a Valdo (60A 12V).
The problem I think is that we have a "dump" regulator and not a smart one, the only smart regulator I have found in Greece are the Sterling one, which I have heard mixed verdict about, so hesitate to purchase one.
I had the alternator overlooked at a local workshop who cleaned it and change the bearing etc, he said it work fine. what does mean?, he could not supply any smart regulator unfortunately. now it  start to charge at 1800 rpm and give good amps at least in the beginning. If I reduce rpm it still charge but Amps goes down rather quick. We have had rather good charge rate on our batteries most of the time as we have the solar panels, but still it should start to charge at least at 1300 rpm.

Sorry Bill I thought you answer on one of my previous issues concerning my Alternator, in Sweden not many have the name Paul, so I react instinctively on that name

Paul the amps has to go down; because that is an intelligent system since 80 Years . Your batteries are full! Periode! Learn more to google it ; alternator...
smart regulator gives you more input during the time the voltage is under 27.8 volt, them any regulator stops charching your bat. makes sens
Valdo is french

Sorry if I offended you with the word "dumb" regulator it was an analogy from smart phone and dumb phone I thought it was fun to use the analogy, not intention to complain on any French product, besides, my Alternator has Valeo Made in Turkey stamped on it, but it might be a French Alternator made in Turkey.

Bill,
I don't know where its made, but its being sold by YachtBoatParts.com in the UK. I don't know about isolated ground either! I guess I'll find out. It is supposed to be the exact same part.

Paul,

You should ask the country of origin and about isolated ground. This is not a part that I would risk on randomly good and bad manufacturing in China.

Good luck!
