red charge light in dash

[strictlypersonl]

IMHO, 11V is way too low to be useful. It means the battery hasn't been charged in a long while. ~12.2V (engine above idle speed) is a good indication that the system is malfunctioning, either from a a super-high draw or low output from the alternator.

You do realize that you have an ammeter gauge that will let you know if your charging system is or isn’t working properly?
