120 amp alternator

[dieselsmoke]

I have my 1.9 aaz td engine and I was looking at getting my 90 amp alternator rebuilt and have the clutched pulley put on it. Before I do the rebuild, does a 120 amp alternator bolt directly on or is there modifications needed???

its a direct swap but with no w terminal for the tach.

there is a way to make your own W terminal by opening the Alt and adding a diode or something.. like that..

Search for it on here.. someone wrote about it. or google adding W terminal to alternator or something.

Easy - the W is a lead between one of the coils and the bridge rectifier (diode).

i am running a 120 amp Alt. on my AAZ with a working tach....

i got the alt. from a VR6 Corrado its a 120 amp i switched the pully and its direct bolt on

works great!

perfect. My only other question is, part of the reason I want to go this route is for the clutched pulley. Will the clutched pulley work and line up properly??

I have a 120 amp alternator on my aaz motor from a 98 golf with an aba motor....has provisions for w terminal....not sure what else to tell you...

Were your lower amp core returns accepted for the 120 amp?

Just wait a week or two before returning the core. They won't remember won't came in the box. Most of the time they pitch the boxes and ALL cores go into the same 55 gallon drum in the back.

Will the clutched pulley on AAZ alternators and "w terminal" driven tachometers give you RPM drop on deceleration?

no... you do not see pully in tach...

90% of the time no but mine has done funny things once or twice.
