Hi Mirl, two suggested sources for constant power:Where did you tap into power? Did you maybe tap into something that is timed like the courtesy dome light that turns off after a minute?
On my car, the cig lighter only has power when the ignition key is turned to Accessory or On. In other key positions, the cig lighter has no power. (This is typical for import cars. On some domestic cars, the cig lighter has power all the time.)i tapped into the fuse for the cig lighter.
