Generator Issues

[jwaldrich]

My 1940 LaSalle has a new generator and new voltage regulator. On a test bench, as a pair, they work as advertised. Put them in the car and I get about 1 volt out.

I've patched in another gauge but same story... not working.

Ideas??

You have covered 2 legs of the stool. The third leg is Whyr.

What do you mean you've got about 1 volt out? Did you actually test is with a multimeter, straight after the regulator? If exactly the same setup was tested good on the bench, was installed together and the wiring was not messed-up, it is generally expected to work, unless it is a really bad coincident...
Do you see any changes in if you increase the RPMs?

Does this have an amp meter?  If so those in general seem to often cause problems and would be one thing different than your bench setup.
