Normal, DTC free amperage draw, engine running

Yes, have conducted various diagnostic tests and have not discovered any numerical values, per my request, and assigned factory specs, and my question has yet to be answered and my quest for the answer. I am searching for the DCA output when all systems are operating normally and correctly, and measured at the battery terminal. Simply a ball park figure would suffice just fine, thank you for your time, sir.

Greetings Steve, Many thanks for all of your combined experience and valuable info you freely passed on to me. Obviously, I do not have access to a break out box where I could monitor the amperage draw of each individual circuit and component, especially those like the fuel pump that draw 5-7 amps. I realize the amount of amps measured on the positive battery wire is the summation of all devices powered while the auto is parked and running at idle with all accessories in the off mode. You would think that the factory would have published an established base line of consumed current measured when the car is brand new, operating under the mode mentioned. As stated in my original question, the Battery and Alternator are brand new; plus the car has been garage kept, totally enclosed in a HVAC environment; and relatively well maintained. Connectors and wiring termination points have been inspected and tested for corrosion from moisture, complete with voltage drop tests made to verify the results. No electrical problems have occurred since the original owner purchased the Lincoln brand new in 2003, the car has never been abused; and most of the accumulated mileage are highway miles. I will agree with your assessment that the electrical/electronic components should draw no more than 10 amps, maybe a bit more, but not more than 13. I have been searching for a ball park figure of amperage draw and I realize the answer is subjective to numerous operational variables. As you mentioned, the fuel pump draws at least 5 amps, plus other components like the digital dash info center, the new alternator, the PCM; and the alternator field windings/internal voltage regulator are the main power consuming devices under the parked/idle mode. When I find nameplate data tags on new components such as those mentioned, I can refine the estimated, or calculated amperage draw number anticipated. For example, on the new alternator, the PCM feeds a PWM signal of 400 Hz at a continuous 2 amp rating into the voltage regulator within. Have read the nameplate data on a new fuel pump, ect, although the amperage value printed are max amp consumption values. I can easily construct a fuse extension module that allows easy access with my DVOM to measure individual circuits amperage draw; and eliminate[disconnect] components I do not wish to measure that may be wired in parallel with the component in question. Some electronic modules, though not operating during my tests, draw small amounts of current in their standby, quiescent mode. As you mentioned, all of these factors have to evaluated under various testing modes in an attempt to acquire an 'average' consumption level. You, sir, are the only mechanic who responded to me after numerous inquiries. It appears no one, except for you Steve, can even begin to fathom an answer to my question, I considered my question to be quiet simple as I assumed someone with IATN or similar[ identifix] access would have a base line value stored within their vast database. You have been most helpful Steve; and I sincerely appreciate your input and the time it takes to sit down and answer my question[s]. Please feel free to add any additional info or insight to the question, if time permits; and once again, Thank you, sir! Marshall

Greetings PRP,
Thank you for your response to my question. I have been looking for a baseline figure[ number] of the amperage consumed in the test mode described. There are no alarms indicated of any kind on the communication screen, no lights, warnings or DTC's stored in rom. Experiencing no electrical/electronic problems with engine components, simply seeking out a number from someone who may have stored this figure in the back of their mind while diagnosing a Lincoln DC charging system. Your information was incorrect regarding the factory announcement of discontinuing the Lincoln after 2002. Town Cars were manufactured and sold in the year 2003; and were not discontinued as you may have read. I have a 2007 Lincoln in my driveway at the moment. Thanks for your help and the questions you posed.
