Pardon me if this has been convered previously.
I seem to have a slow battery drain on my 82 300SD. I have found that the relay in the "A" position is always clicked on (removing negative battery cable causes it to click off) and remains consistently hot to the touch. I will see if I can decipher what that goes to and whether or not that is normal (doubtful). If anyone has any input it would be greatly apprciated. I'm off to decipher the wiring diagram and try to get this sorted.
This is my wife's car and she's already needed to get it jump started twice

. I don't feel like getting another car, so help is apprciated...
