The third relay in the voltage regulator is called the cut-out relay and it's suppose to open when the engine is turned off which opens the connection between battery and generator.
If this doesn't happen, the battery 'motors' the generator...turns it into a small DC motor and turn its.
This contact can weld itself shut causing this problem. I don't know if you can repair or file the contact back to life!
More knowledgeable folks will be along soon.

This can happen when you have disconnected/replaced the generator or voltage regulator; or, if your battery has been recently replaced (and your truck had not been run in a long time). | | |
