Works > perfectly, problem fixed...? I suspect that the problem with these are a few shorted turns in the field winding. This will bring the winding resistance down a bit, but probably not enough to detect with an Ohmmeter. I suspect that the only real test would be with an inductance meter, since that should show a high Dissipation factor for a coil with a shorted turn. The problem with all of this is that automotive shops are seldom set up with the instruments necessary for this kind of testing, although I'd expect that an automotive electronics rebuilding place SHOULD have something that would pick out shorted field windings. I've personally never tried this, but I have a meter that MIGHT be able to test for this. It would be interesting to find out.
