I had a problem where my battery was draining. Charged it fully and disconnected it. Battery stayed charged. reconnected battery and voltage was pulled down to 10.5 volts. Started pulling fuses to find circuit that was the culprit. Pulled 15 A fuse for dome circuit under hood and voltage went back up immediately. Where is dimming circuit module for dome lights so I can replace it?

update - thought the dome circuit was the culprit but after 2 days the nattery is back down to 10.8 volts. Battery is only 2 weeks old also. could it be the alternator?

Use your voltmeter to see what the voltage is at the battery with the engine running roughly 1700 + RPM with the defroster on high and headlights on. report back.
