Charging Problem 87 5ktq

[JJK1204 at aol.com]

John here, the original poster, I should try to straighten this mess out. I 
was only trying to explain the symptoms of my problem. I believe that the 
alternator is fine, the blower motor is not the culprit since it happens with 
any device to greater or lesser extent, i.e., the rear defogger, the radio, 
the interior lights, the headlights, the blower motor, the seat heater, the 
emergency flashers. I am looking for direction as what can cause this other 
than the fine alternator and the small wire that breaks and was repaired. I 
haven't checked some of the recommendations, but they include bad battery, 
recheck the alt belt and I have not ruled out the ISV etc, although it seems 
to run fine on a fully charged battery. A question for DeWitt is where is the 
feed back wire in the fuse box? Also where is/how do you get to the "infamous 
passenger footwell splice" location? I would appreciate some opinions on 
whether this is an electrical or ISV/intake type of problem. In fact the 
reason I got the new alternator is for similar symptoms last winter.

Respectfully,
