Re: Alternator brushes?
Thanks for the advice. It has been baffling me. It seems to have sorted itself out for now, but I know that it is merely lulling me into complacency. Heard about pre-excitation of the alternator? found this on a alfa site...."A power diode and an exciter diode are connected in series for each phase of the excitation circuit. Self-excitation can only take place when the alternator voltage exceeds the voltage drop across the two diodes (2 x 0 7 =3D 1.4 V). It generates a magnetic field in the rotor which results in increasing generator voltage in the stator and so to speak, helps the self-excitation to "get going"."
Does this sound feasible? If so, it still points to the voltage regulator.
It seems to be an absolute mission to get to the alternator, so I will nurse it along...for now!
