voltage regulator question

[Guest imported_PackardV8]

Good question JT. We mite conjecture that by 1929 to 32 that American driving demands had certainly began to graduate from the model T hand crank era into something that actualy resembles a car. Therefore, more electrical demands as well as HIGHER ENGINE RPM. Trending away from mag ignition to coil y battery. These more 'modern' factors probably resulted in a need for finer control of the charging systems.

However note, that 47-48 model year transition of Indina motorcycles saw a 3 brush gen with 2 stage REGULATOR in 48 as opposed to a 2 brush gen and cutout in 47. The Packard transition seems to be in the opposite direction.

SPEEDSTER:

HOW is this 3rd brush actualy adjusted??????? Does it require removal of a band around the generator or is there a small lever on the end of the gen that can be moved by hand????????

I think there were about 4 different models of 3-brush generators , made by Owen-Dyneto, that were used by Packard during the '20s. Some had a small metal knob protruding from back end of generator and some only had a sloted screw that you turned. These moved a small rack and pinion type assembly, that moved the brush slightly. I think there is only about .3" maximum movement of the rack. (The '29 had a screw type adjuster)

There is a dome shaped cover over back end of generator that is removed by loosening 1 screw and rotating the cover slightly, to get to the adjuster. The model # of the '29 version is CD-840.

There is also an Internal Fuse in those generators, that needs to be checked. I forgot all about the fuse until just now. <img src="http://forums.aaca.org/images/graemlins/blush.gif" alt="" /> <img src="http://forums.aaca.org/images/graemlins/grin.gif" alt="" /> (It's under a small metal cap)

Some voltage regulators (especialy pre 55) also have a fuse under a small cap that can be easily overlooked too.
