[Roadsters] Datsun Alternator

[Jim Gammon]

Tom
 
12 dvc everywhere. Not more with engine running.
 
Same at back of alternator.
 
Turn on lights, needle shows more discharge.
 
BUT, the white wire feeding down to the starter is not connected to anything.
I assume this must be the problem, but WHAT does it connect to?
 
I must have missed it during installation. I don't know how, there is so much
room to work with in there..... Hah.
 
Many thanks for all this help.
 
Jim

Jim,

The diodes are mounted on plates inside of the alternator case.

There are brushes to make contact with the armature.  When you reassemble
the alternator you should look for small holes in the alternator case
through which you insert wires to hole the brushes away from the armature
util you have the case reassembled.  Then pull the wires to release the
brushes.  Clean the armature up with very fine emmery cloth.  The diodes
require an ohmeter to check.  Assembling the alternator should be pretty
straight forward with brush wires in place.

I guess I need to finish the Leece/Neville alternator training manual
published in 1959 as a training manual for the introduction of alternators
in the 1960 Chrysler products.  There is some good info there.  The scans
are done, but I have not had time to get it into PDF format.

Thanks to all who advised.

I checked all connections. I took the cover off the regulator and lightly
cleaned the contacts with 600 grit.

I can't find anything on 311 unless I want to change alternators. I
don't
know
where the diodes are, and one suggestion was to look at the brushes, which I
don't know anything about at all. I thought only generators had brushes.

I did find this on the internet, but I'm not sure which drawing applied to
a
69 311.

I really would like to figure this out without replacing parts. I really
don't
want to go to the GM alternator if I don't have to.

The charging system worked fine until I took the engine out and rebuilt it.
I
know I connected the wires correctly, but it simply does not charge.
