Optima RedTop steaming after drive
I've been reading around, and getting mixed reports. Some say the battery is shot, others say the alternator is overcharging, and some saying it is the fault of a bad voltage regulator.
Where should I start? I don't want to buy a new battery and ruin it because the fault lies elsewhere.
same thing happened to the battery in the Trailblazer I bought, the guy left it sitting dead for a week then jumped it off and after noticing the odor during the test drive I spotted the battery hissing and steaming, used it to get him down on his asking price and bought a new battery, been 2 months with the new battery and NO issue since.
