I have a 1984 Chevy pickup (carbureted) that I plow the yard with in the winter and it sits and rots the rest of the year. Lately it has to be jump started because the battery doesn't have what it takes (click click click).
The battery is an 1100 CCA Duralast Gold from Autozone, maybe 5 years or older (my memory sucks). It's been neglected by my forgetfulness to maintain it during the summer months. The alternator is a re-manufacture from Autozone that I installed maybe 5-7? years ago. The truck probably runs about 20 hours a year.
After the truck sat unused for 5 days the battery measured 11.9v. I jumped it and with the truck running it measures 15v. With the truck running and battery disconnected the leads that would hook to the battery measure 15.8v. I'm trying to determine if there is a battery or alternator problem.
EDIT: The 15v+ measurements were while the motor idling but cold, so RPM's were higher than a normal warm idle.
I don't mind replacing the battery and/or alternator but would appreciate opinions on the matter. I don't want to put in a new battery if the alternator is going to assassinate it. 15v sounds high to me, what says you? Thanks.
