Putting my correct use of the meter aside and during further inspection, I heard air escaping near the front wheels but the rain kept me from getting underneath to discover the source. Could the amp draw be from the air compressor running - which doesn't start until after the engine is running? The Freightliner/Fleetwood interface electrical drawings are incomplete, erroneous, and downright confusing. Btw, the daytime temperatures here are in the 60's and 70's and the diesel batteries were fully charged before starting so the alternator output should minimize within a reasonable amount of time.
