Just fitting my new alternator, replacing the old Sevy Marchal.

Three of the four connections are obvious (I hope)

The positive, and negative and the green field connector are indentified.

At the same time I am re-fitting the Adverc charger control.

This identifies the 4th connection as a low current output called one of the following -- Ind, D+,61, Lterminal.

Lookiing at the picture above, the Positive Negative and field seem to be obvious.

Its this low current output that I am not clever enough (I wish) to indentify.

The Adverc wiring diagram might be indicating its the AC TAP connector.

But their diagram is really only for fitting their system, and not fitting the alternator to the engine.

I can ring Adverc on Monday, but hope to get it up an srunning before then.

Any ideas?
 
D61 on mine, (and it seems quite common with all alternators, having googled it), is the wire that activates the warning light, and possibly excites the alternator, (whatever that means).

Mine is a brown wire which, (after some tortuous route), ends up going into the engine control panel PCB.

This thread might help?

VicS seems to identify all/most of the wires/connections very well if you scroll down



Hope this helps

Not feeling in the mood for trouble shooting alternator problems at the moment. Knackered after an afternoon in the garden!

I expect Ac Tap is as suggested the connection for a tach ... normally labelled W

The warning light connection may be the terminal labelled EXC on the basis that the warning light provides the initial excitation current to get the thing going.

Have you looked at the Leece Neville website. there seems to be a lot of info there. I have not studied it but maybe there's a wiring diagram on there someplace.

Get the new alternator installed and running before you start fitting the Adverc or you wont know where you are.


Note to Richard.
Just like you and I alternators need a little bit of stimulation or excitation to get them up and performing. This is provided by a small current flow provided by the warning light .... a little foreplay /forums/images/graemlins/grin.gif

Well off you go and have your foreplay and whatever..... see you in about 5 minutes /forums/images/graemlins/laugh.gif
 
Thanks all.

Eventually went for the Excite lug.

But am really fed up at the new alternator is just too big to fit!

The terminals are just fractions of a millimetre from the exhaust manifold! Being clever is not my forte, so having detached the regulator to give more room, the terminals were still to close to the manifold.

Back to the drawing board!!

But some like it a bit rough too!!!!!!! Can always try a 5 pound lump if no 12 volts around...It worked for me /forums/images/graemlins/smile.gif Mind it was a 300 hp Bellis and Morcom jobby delivering 240 volts DC.
