Hi Jim,

Had this on my car only more extreme.  The idle was varying with the turn 
signals and I couldn't exceed 3000 rpm with the headlights on!  Spent about 
3 weeks sorting out the wiring and wrote a couple of posts on the 
subject.  Even after this, I still had a faint alt. light at 
times.  Careful voltage measurements showed that the voltage coming from 
the "61" terminal was higher than the power at the instrument cluster.  In 
other words, a small reverse current was causing the bulb to glow dimly.  A 
3 amp diode placed in series after the alt. light solved the problem 
completely.  Electrical system is very reliable now (fingers crossed!) and 
I haven't put in the fuel pump relay mod yet.

If you'd like to see the what I went through to shut off the alt. light, I 
can dig up the post and send it to you.

Regards,


-Tony
