garystocker Member Jan 2, 2005 305 0 17 New Jersey Dec 30, 2005 #1 Dec 30, 2005 #1 I just picked up a 68 GT Coupe with digital gauges. It was driving well for a couple of days. Digital voltmeter read 14.0 steady. Now it reads 11.5.. Is it the battery, voltage regulator, or alternator, and how can I tell? They all look newer to me...
