For a couple of months now, as I drive, the voltage appears to get lower. The headlights dim a little or the wipers slow down.
Then, today after driving about 15 miles, and stopping at a store, I needed a jump to get it started again.
I got it home and did some diagnosing.
After some rest, the battery was 12.7 volts.
I started the engine and the voltage was immediately 12.4.
I let it idle and the voltage kept coming down. After about 1/2 hour, it was 11.6.
Could it be anything other than the alternator?
Thanks.
