Hi Volks,
    I'm still plaqued buy generator problems on my 84 bus.  2 weeks ago
I put in a new generator because tthe dash lights failed to light and it
turned out it wasn't charging.  Up until lunch today its been working
great.  Now the lights come on bright and then goes dim after I start
it.  I checked to output and its right on 14.5 volts at the output stud
and 13.5 volts at the battery.  The output at the blue wire  is 13.5
volts as well.  I  turn the key on and remove the blue wire  the lights
go out.  I ground the wire out and it lights up.  I'm at a loss. Tech at
work said he thought that the blue wire output was only supposed to be 5
volts.  For shits and giggles tonite I checked the output of the
generator on the Syncro I've been working on and its 14 volts at the
output stud and 13.5 volts at the blue wire too.  Any ideas?

    As I understand the dash battery lite system, the light gets its
ground from the generator and then when it starts charging it sends
current through the blue wire and since current is already flow in it
cancels each other puting the dash lite out.
   Since I'm getting current out of the generator, I'm thinking I'm
getting a poor ground somewhere feeding back on the system and turning
the light on.
    If anyone has an idea, let me know thanks.
