Alternator wiring
I know there are many threads on this but none of them seem to answer my problem.
On my alternator (dont have the make to hand, I'm at work) there are the normal two large blade connectors and the one small blade. Two large
ones are a common connection and go to Batt, small blade accepts the wire from warning light / ignition.
Question is, my alternator also has one large stud type connection (marked B+) and one small stud connection (marked W) so can I use these as the Batt
/ warning light connection instead of the blade terminal ones ?
I checked the continuity between the large blade Batt ones and they are connected so will it be ok ?
By the way, reason for using these instead of blades is I dont have large spade connectors to connect to them

you really need the large terminals and right size wire to carry the current,smaller ones could overheat and burn your loom out

I maybe didnt make my question clear.
I know the cable sizes etc, question is, can I use the stud connections on the Alternator instead of the Blade ones ? i.e. are they the same
connections ? as my alternator has both types

My escort TD alternator had threaded connectors as well as spade type but it used a round push on connector with a spring clip in it. If the output is
there it should be o.k. to use it. It's easier to use two thinner wires than a thick one to connect to the battery and it achieves the same end.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

i dont see a problem with this as long as there is continuity between them and the one you want to use is not any less substantial than the blade
(which i very much doubt).

B+ is for the battery charging, stud is prefered to the blades, due to lower resistance, better connection.
W is normally internally connected to one of the alternator coils, providing a drive to for examle a rev counter.
D+ is the normal marking for the connection to the charging lamp. Without this lamp connected, the charging may not start.

So, I have one large stud B+ (connect to battery) one small stud W (dont use as it is for accesory) two large blades (same as large stud) and one
small blade (cant see a marking near it), do I use this for warning light connection then from ignition etc ????
Confused

Correct,
Use the small remaining blade to the charging lamp, then going to ignition on, normally called 15.
Even if the marking on the small remaining blade is unreadable, this is likely to the right one for the charging lamp.
If not, I don´t think you can brake anything with just the small charging lamp (3W or so) in the circuit.
