No accessories that I know of...it had an alarm system on it but I disconnected it (I'll check to make sure nothing else is lingering somewhere. So it's really normal for the regulator to be warm even with the car hibernating ?? Wouldn't that draw down the battery over time?

The voltage is the same on the back of the alternator input as the battery itself, the feed comes off the junction block.

I am a quick learner, but I guess need more education on how the regulator/alternator work together. I thought the altenator put out a constant voltage and the regulator adjusted it's own output to the fuse block. So does the regulator adjust the altenator output on one of the 2 wires (Dark Blue) going to/from it?
