Regarding A0014840AAH

Dear Dary
I bought the above said model(A0014840AAH) from your indian agent.I would like to use it with my system voltage of 80volts.since it seems a Ac alternator could you tell how to connect it with Dc rectifier.(i can convert it to dc 80volts by connecting dc to dc conerter from the dc rectifier
I have seen three poles.
like this

ac? 1 f+(?) ac?(which pole)2

ac(which pole)3
Diagram of the rear view of alternator
assume ac pole 1 and 2 are between f+ f- cabin
pole three is against these two poles.

could you please tell me what poles they belong (1 2 3).
and also what is meant by f+ f- .I need to know
what is its ac voltage(ac 220 0r 110) and frequency(50/60hertz) without connecting rectifier or converter.

With regards

How conect my prestolite alternator?


I'm changing to new wires in my Volvo Penta AQ171A. The Alternator is a Prestolite, and the label where to find series nr, part nr etc is empty??

And I have search at your website but I have not find my alternator there.


B+ is market on the alternator.

Then I have D- , and I have heard that B- could be named as D-. But D- is very fussy, so I'm not sure , perhaps its D+??? I need D+, so I can connect the charging control lamp and the external current limit relay (Bosch).


Then its a connection that has no label?!


I have attached there pictures, that perhaps could help you to say what alternator this is. And how to connect it. I would be very glad if you could help me. So I can connect the alternator right, before it was wrong, for example the charging control lamp was connect to W....


Is it something more you recommend me to do with the alternator when I have an extern current limit relay? Best Regards Marcus Alm, in Sweden

Leece-Neville regulator

I would like to update the regulator on my 1961 B Mack. Currently there is a Leece-Neville 3476-R6 regulator, 14 volt, 125 amp, positive ground. What is a good replacement for this?

8LHA2023Y what amp output?

I have figured out wiring, but have no idea what this large alternator puts out for amps. It is replacing a 70 amp Motorola, which wasn't enough. I now have this Leece*Nevelle, bracketed and wire connected, it was building from 14.2 volts upon start-up and climbing. I only ran it 10 minutes, the 70 old amp alt never got above 13.5 connecting the three 185 amp hour, Rolls batteries.

Obviously, the original glue stick-on labels identifying name, model, and dimensions, fell off from over the years making it difficult to identify this alternator. Thankfully, the previous owner etched a model number on the body of the alternator, but only that. I had to gleen the web to find myself here.

I'd like to know what this alt output is rated at? Anyone know? 8LHA2023Y

Wiring diagram needed.

I believe I have a Leece*Neville, Model 8LHA2023Y as it was scribed by hand into the alt. body by the previous owner.

The alternator was removed from the 1977 Perkins 4108 marine diesel eng and sent out to be refurbished over a year ago. I need now to install it back onto the Perkins. I need to know the wiring diagram. Unlike some of the later 8LH series, mine is more similar to the current 8LHP2170V.
looking at the back of my alt, there are 3 terminal posts on top, the NEG OUT on left, POS OUT on right and a single terminal post at the bottom.

I am aware that one wire will connect for the tachometer and the other to the ignition switch, and of course Neg to the block and Pos to the battery, assuming this is correct. I need to know which terminal post is for tach and which is for ign.

Can you help me?

Thank You........Steve
