I have a 2000 Ford F250 with a 7.3 Diesel engine. 153K miles, twin 1,000 amp red top batteries. First alternator lasted 8 years before it
quit. I went through 13 new alternators before I got one that worked. it is a single alternator system with the regulator built in. 30 months later it is alternator time again. Anyone experiencing the same issues?
