You right, I think same way.
But I found that wire from dash to alternator excite circuit is too small to drive excite current. So it have to be, somewhere under the hood, power unit that controlled by little wire from a dash and make excite current to alternator circuit.
After I turn key to MAR position on exciter connection of alternator voltage about 1V. So Alternator LED (it is LED in dash) have to light up, but it did not.
I will disconnect exciter connection from alternator and short it to ground, but I think result will be the same - no light.
p.s. After start, on idle, voltage is about 14V. No need to rev up for alternator.
