Mex, what accounts for the initial 37 amps I saw and the quick taper to 28?
Starting (chassis) battery voltage only got measured at 14.59v after the quick decline. Was starting battery voltage higher at first and I missed that? If so, I can set up a test on that but I will need an assistant ( such as DW in the driver's seat with me at the battery)
The voltage regulator controls the output voltage (and therefore the charging current) by comparing a engine battery voltage to the preset voltage of the voltage regulator. If the battery has a lower voltage than the output of the alternator current will flow. Large difference will means MORE current will flow.
It is hard to understand but, there ARE two different voltages when the battery and alternator are connected by the same wire, but THERE ARE. If you don't understand Ohm's Law and how a simple (not smart) automotive alternator works you are just going to be fighting ghosts.
