Check battery voltage, car running, is 14 volts or above. If that's OK you could have something draining, check the dome lights above the rearview mirror, those are easy to leave on (some cars may not have these). The radar detector will drain the battery if it's cold weather, although newer stuff draws less power than my old Passport!
Checked the battery voltage the first time this happened. Went up to 12 maybe 13 volts then towards the end of the test cycle (had it done at Advance Auto) the volts went down to 4-5.
The dome lights are off and have been. I have had my radar detector for 2-3 years now and it has never drained my battery, that I know of. It hasn't been very cold here but in the middle of winter I left it on all the time and my car still started in -40 weather. What are the diodes in the alternator? My dad doesn't think it can be the alternator. For awhile my subs have been popping at high volumes, prolly from lack of battery power. I am puzzled! More ideas please.
