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:
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!
