1989 Grand Prix SE drain on battery
Fully charged battery will discharge
after a few days with nothing running
except the clock. I notice that all the
gauges on the dash show a reading
when the car is entered but key is
not in ignition. When key is inserted
and turned, the gauges return to '0'
there is a good vid on youtube at scottykilmer.com about finding a parasitic draw on your battery
From your description I would suspect a faulty ignition switch that is failing to shut everything off when it is in the off position, but that is only a guess. As always troubleshoot first, buy parts later, and always remember that free advice (like mine) is often worth exactly what you paid for it.
