Thank you, Dave.  Perfect, I will find a shop.  All the best.

For my 2003 Lexus RX overnight battery drain, mechanic determined in was a constant 4.2 amp draw coming from somewhere INSIDE the vehicle.   But, it was NOT the Multiplex Body Control Module said to be the specific problem by some.  I have checked the full diagram of the vehicle's electric system but it does not break down specific sources, likely since they probably all go thru large amp points.   Is there a way to find single sources of a 4.2 amp electrical draw, which I might be able to fix or disconnect??

Thank you for any suggestions.  John L.
