I have just received a new Alternator for my 1988 Quad from Classic Alfa in the UK.
The original alternator (see pic 1) Has the red positive wire connected to the "B+" terminal and the green wire connected to the "D+. There is no "W" terminal
terminal. This is correct per the service manual wiring diagram.The black capacitor is connected to the + terminal.

Now look at picture 2, the new alternator. Out of the box the capacitor is connected to the "D+" terminal and there is no "+" terminal but there is the "W" terminal which I think is a tachometer connection for a diesel engined vehicle.
I know I have to connect the green wire to the "D+" terminal. Should I also connect the capacitor to the "D+" terminal?
I know the capacitor is only there to cut down RF transmissions from the alternator so I could just remove it as I never listen to radio stations in the car any more.
Thoughts guys?
