Actually, there is a load on the engine. The alternator has to supply all of the necessary current for all of the electrical loads that are "on". There are the radiator fans (20 amps), A/C condenser fan (9.5 amps), A/C compressor clutch (2.8 amps), plus the gauges and the ignition. There is also the load of the A/C compressor. All of these items add load to the engine, and each reduces the idle speed of the engine (as noted in the test results), which slows the water pump.
