Brand: Auto Meter Gauges
You have to disconnect the battery before working on your car to avoid shorting and frying sensitive electronics. But when you cut power, those sensitive electronics lose their memory. Everything from throttle maps to shift points to your favorite radio stations has to be re-learned or reprogrammed. The Auto Meter Smart Power System is the answer!
Simply plug the SPS-12 into your OBDII port before disconnecting the battery. The SPS-12 not only provides a constant power supply to preserve settings and memory, it can even alert you to a parasitic draw or short circuit! Ten LEDs indicate power in, status, and the level of current being drawn. Runs on AC power (110-240 VAC, 50/60Hz) and supplies regulated 14 volt power at a maximum of 4 Amps, enough to keep electronics awake but low enough to be safe. The included OBDII port works with all OBDII-compliant vehicles (generally street cars built after 1995).
