Re: Battery light '06 Denali
I got home last night and put the digital voltmeter on the battery, it read 12.7v with the engine off for about half an hour. I put the smart charger on and it said 97% charged and only took 15 min to get fully charged. Battery light still on while running. I unhooked the negative cable at the battery (was not real tight) and reconnected in 10 min, no light on dash, no issues driving the treacherous 2.25 mile commute to work either.
