durning summer months, the charging indicator reads 11-15v

This problem only shows up durning the summer months.The outside temp is 88 degrees or above. the charging indicator starts out reading 15.5 v which is normal then its drops to about 11.0v or somewhere in between. As you drtive it varies between 11v and 15.5 . I can not make it read any certain way , good or bad. It appears that the voltage regulator is not working properly. I exchanged the altanator 4 times because the regulator is located in the alternator. The truck never failed to start, so I gave up. It is a scarry feeling to look down at your indicator and see your gauge reading 11 volts and you are i8n the middle of nowhere on a Sunday morning. apparently the problem is not in the regulator or the alternator and the truck is still working.
