The alternator in my Cherokee has been whining lately. Whining as in whistling, not whining from a bad bearing.
Voltage has been around 13.5 or so running (correct) 12/11.5 off.
The battery was bought in 2008, a Napa Gold. Due to some electrical issues my Jeep had this time last year, the battery has been killed 4 or 5 times. Plus, being a 4 year old battery, it's due for replacement anyway.
The last time it randomly went dead, I installed it wrong and crushed the top of the case in and it kept leaking. It ate some plastic stuff and corroded the terminals.
Sunday night at 1130, I was at Walmart buying some stuff on my way home from a huge jeep show. Went to start to leave and I got the clickclickclickclickclickclickclickclick.
I ended up getting some baking soda and water, cleaned the terminals and got it started. Figured that was the problem.
Last night it did the same thing on me at Tractor Supply. Cleaned off the terminals in a parking lot, sanded them, best I could get was about 10 volts at the battery cable. Went to Advance to look at battery cables and it did the same thing again except I couldn't get it to do anything.
Bought a battery there (out of desparation) and put it in.
Voltage on the new battery was about 12 (it's been sitting 2 months). After driving around for a bit, I checked with the vehicle OFF and it was about 13.5 ... which I couldn't achieve any more with the old battery.
Anyway, my alternator is not whining anymore, especially after a start.
