Hello,
My wife's 94 Lexus ran into a strange problem yesterday. She went to a meeting and after the meeting the car was completely dead - no power, no
lights and had to enter with the key. I wasn't there but the tow truck driver said he jumped the car but the car still had no electrical power. I'm not sure.
The car was towed to the dealer and the dealer mechanic jumped the car (
while I was there) and it started. The mechanic said you have a bad battery. This was my initial guess. Since the car started, we drove home. I measured the battery voltage and it was 12.5V with the engine off and 14.0V with engine running (bad battery?). The car starts OK now
with the 'bad' battery, but I changed the battery anyway.
My question is: Can a completely appeared to be dead battery come back to life or partial life? Or is there a power cutoff feature in the Lexus?
Thanks -
