49 Battery not sure but could be alternator.
57 Low voltage usally means no power getting through so make sure everything is plug in propley.

I'am sure more experianced people will be along soon to help. :y

Measure the battery voltage at a fast idle with not too many electrical loads on. If it's over about 14.5 volts you probably have a failed regulator module on the alternator.

Do the battery check as Kevin Wood says :y

Is the idle rock solid, or does it fluctuate?
