Quick alternator question (w114)
Just bought nice reman. Beck Arnley alternator.
Fits perfect but the wiring kind of stumps me (see attached). Outside of the 3 prong voltage regulator (which goes to my external voltage reg; pretty straight forward) how do I hook up the other two (b+) ones.

Oh, also here is the wire that it hooks up too (notice how it has 3 wires/3 female hook up). Two wires look pretty fat (gauge), and one blu one is thin.

Humm...could it be that I have actually stumped everyone (40 views no takers)?
I was fishing around and came across a similar question posted on a VW site: TheSamba.com :: View topic - B+ B+ Alternator with pics Bottom line: the two red (thick gauge) wires both go to the B+, and the thin blue line is the one that goes to my dash warning light (which I'll hook up to the spare B+ terminal). For whatever reason, my new Beck/Arnley alternator has two B+ terminals (one marked B+ and the other marked B+B+); they are exactly the same. Aside: that little black doohickey attached to middle is to reduce radio interference (ever since my alternator was on the fritz my radio has been making humming noises); cool.

Just my two cents....but the reman alternator that you have there looks like a Bosch AL64X 35 Amp alternator and the alternator that you took off your car looks like a Bosch AL74X 55 Amp alternator.
I don't know the W114/W115's as well as w108/W109's , but the 1966 through about 1969 w108's had a 35 amp alternator. The later model years w108's had a 55 amp alternator If I were you i would go back to the place you purchased the reman alternator and see if they have the 55 AMP alternator. John |

It looks to me like ALL the connections are different on the new alternator.
You'd have to cut off your old connector and install ring terminals to connect to the B+. Take it back and ask for the right one, or take your old one to a local rebuilder.

Well, the good news is my radio sounds perfect (no interference).
Bad news is I have a 35 amp alternator when I should have a 55 amp (cripes!!!) Well, re-ordered a Bosch 55 amp-er (overnight delivery). Hopefully be here for install by my day off Wednesday.

Update...nasty squeeling noise comming from engine early in the morning...sounded exactly like what has been described as a "loose alternator belt".
Sure enough, pulled off side of road, loosened alternator adjustor bolt, tightened belt: smooth sailing since then.
