Simple question, I think. With engine running and no extra electrical loads turned on, my voltmeter reads a bit over 13 Volts. Turn on headlights and voltage drops to a bit above 12 Volts. Is that a normal drop or is something going on with the voltage regulator or alternator?

Almost ALL old car alternators make little or no output below 1500 rpm. The exception is some old Dodge units make power at 1100 rpm. Newer cars are different with all the electronic systems many can make power at idle.
Your reading is normal at idle. |
