Ok, here's the situation. When I start the car cold I get 13.2 volts across the battery terminals. Perfect, right?
As the temperature gauge moves towards the middle of the gauge I slowly loose more voltage until I'm down to 12.2 volts. Is this normal? I'm thinking that at full operating temperature with no accessores (lights, brake lights, etc) I should have full charging voltage. It seems that something is kicking in as the engine warms up and draws a full volt. Are there any D-Jet components that would draw voltage as the car warms up. The voltage drop is gradual. As the temperature gauge goes up the voltage gauge drops in sync. And this is not a faulty voltage gauge issue. I've verified this with a volt meter across the battery terminals. |
