I am completely stumped with an alternator light
problem.  The idiot light stays weakly lit constantly
and I can't find a short anywhere.  The alternator is
new and kept the light out temporarily but began to
weakly light again.  Does anyone know how the Bosch
voltage sensing system in the alternator works and is
it prone to isolated failure?  I suspect that faulty
wiring somewhere caused the failure of the sensing
circuitry and now the alternator has a voltage output
of higher than the battery and creates 2 different
potentials across the idiot light. I have ruled out
the starter and refer as short suspects.  Could a
short in the battery cause this?

Thanks
