760 b27e alternator problems

[Victor]

G'day all

Just a question regarding my wifes '86 760.
It seems that the alternator is dead, using a voltmeter to read
directly off the battery, I get a reading of roughly 12V. Once I start
the car it drops to 9V AND no matter of revving will make go higher.

I'm thinking that the regulator may be stuffed but am open to other
ideas.

Otherwise can I just replace the alternator with one from a 4 cylinder?
(The 760 has the B27E).

cheers

The regulator should be screwed to the back of the alternator. It looks like
a large power transistor with plastic covering. The alternator brushes are
part of the regulator. Take it to a Bosch agent who can test the alternator
and regulator and supply the correct type of either. Alternator is on
exchange basis but do not know if reguilator is also. I reckon that the
brushes need replacing but just as quick to replace regulator complete with
brushes. Anyway your Bosch man should be able to solve your problem.

All the best, Peter.

Thanks Peter

I've got it in a the shop now so hopefully everything will turn out
alright.

The regulator may be a bit hard to get hold of here and the only(?)
replacement alternator Bosch had in Australia was 650AUD!, so hopefully
this guy can work some magic for a bit less than that, otherwise I'll
have to call some friends over in Sweden to do some junkyard hunting
for me

Has anybody in Aus had luck swapping a unit from a another make ie
Commodore or Falcon?

cheers

Just an update.

The alternator had a burnt stator winding so I ended up calling up
several faraway wreckers and got hold of a used unit (95AUD).
