By the way, this is my problem:
Here are the symptoms
1. Engine tends to get hot in stop & go traffic especially at night.
A. Constant cruising speed - temp is ok.
B. System voltage with fans off is about 14 volts.
C. Turn fans on (day) - 13 volts initially but will drop another 1/2 volt with lots of stop & go.
D. Lights on, fans on - 11.5-12 volts over time in stop & go.
E. Light switch body gets prett warm with lights on.
F. Some wires under dash get pretty warm, especially in the white plastic connector near ignition switch.

I've already swapped in a 100 Amp alternator, checked all grounds I could find, checked battery terminals. When the system is reading around 12 volts on the dash I have put a digital meter on the battery and found approx 13 volts there.
Has anyone else had a similar problem?
