What causes a check transmission light to come on the airbag light to come on and the volt meter to climb all the way to 16 in a 1995 Isuzu Trooper?

Just fixed the same problem with mine and its a bad alt . the votage regulator goes out on them and causes a bad ground to the rest of the system kepping the battery light on o2 light and brake light on also causes the trany light to flash. change the alt and it should be fine Just fixed the same problem with mine and its a bad alt . the votage regulator goes out on them and causes a bad ground to the rest of the system kepping the battery light on o2 light and brake light on also causes the trany light to flash. change the alt and it should be fine
