While driving at night recently I noticed that my lights were pulsing
ever so lightly. Hardly noticable but when I looked at the amp meter I
saw that it was pulsing also. The needle ticks back and forth across
the + side. It also looked to me like it pegged on the + side when I
used the retarder.
Thanks for your help,

I notice the same thing when the primary power is coming from the
engine alternator -- some of the lights pulse -- especially the 120 v
incandescent lights in the bathroom -- this is particularly
noticeable when the engine is at idle. I presume that the alternator
output is varying slightly at low RPM. I assume that the variation is
below the level that the regulator can control... However, I haven't
noticed any movement in the gauge needles when this is occurring...
(My retarder is not electric, so that isn't an issue for me.)
