What is this off?

What car is the alternator on the right of the picture from?

On the left is my RHD 924 alternator.
The route of the heavy duty cable goes from the large post with the insulator, then between the central boss and the voltage regulator and then over the top of the small triangular opening.
This is when the 'normal' heat shield is bolted on.

The alternator on the right has the cable connections in a more sensible place but it doesn't work with that heat shield.

Don't know what it is from, but the front and rear of these alternators can be "spun" in relation to each other - do that to either of these and it will be identical to the other - then it should all fit correctly, including the heat-shield.

Regards,

Tref.

I'll second that-it has just been assembled an!alternate"way.[]

Ho ho very droll

why didn't I think of that one . . .

And Tref yes the rear casting needs to be turned round, but do you know if the internal wiring to the diode plate will be long enough? Maybe I'll have to strip it down and find out . . . I could do with using it as the rotor pickup points are in much better condition.

What I don't understand is why Porsche would design the heatshield so that the cable has to be routed right across the back of the alternator?

In the past I have removed the three or four long bolts, and without any further dismantling spun the two halfs of the casing, and reassembled without problem. The alternator even still worked afterwards! I was shown this trick, but do not know if it is the "correct" procedure. I have just done it more than once without problem... the result is I never bother looking to see which way round it is for a particular vehicle, because I haven't ever found a problem changing it!

The same same applies to the old Lucas ACR series alternators if anyone remembers those...

HTH,

Tref.

Cheers for that - good to know its possible. I might also have to get the pulley off the front as its on the huh - as we say round here.
