Ok, I have been noticing an issue with the Indy. It seems that when I have some accessories on in the car (headlight, heat and wipers) that when it gets to 900rpm/idle my voltage drops to 11v, according to the gauge. I believe the gauge because the headlights get dim when the gauge drops. When the rpms increase, by just a couple hundred, the voltage is back around 14v.
My question, is this typical in the 4cyl auto or is there a fix for this?
