I don't want to complicate this thread too much but, I received my charging/battery voltage indicator LED , and it is just want I wanted. If the static battery voltage is really low, it will show red. If it is slightly down it will show yellow and once the charging system provides a proper voltage, it registers green. It has other features to monitor extreme high voltages etc. Since I have taken delivery of my 1957 Skyliner, and it is outfitted with an alternator with no charging light indicator, I am going to install this in the dahs, in it's place.
