154 Starter Generator Question
Posted: Thu Dec 27, 2007 7:33 pm
Hi - I was trying to work my way through the generator / regulator flowchart on Rudi's website and I have a dumb question.

As you progress through the tree, do you keep adding jumpers, ie after step 2, do you keep that jumper there and then add the next jumper?
The reason I'm asking is that I've been measuring the voltage at the armature terminal back to battery ground and the voltage decreases from around 3 volts at idle to almost 0 at full speed. I have polarized the generator, even though I suspect it does it each time since it is a starter/ generator.
Perhaps I just ended up with a dog of a new starter/generator but I can't figure out why voltage would seem to drop with an increase of RPMS?
Thanks - Lance
