My 98 saturn sl has had a slow battery drain problem for a year and usually starts up with a small jump if not driven for 2 or 3 days, but now the problem has gotten larger and drains a fully charged battery in ten mins and won't take a jump easily to get started. i tested the battery which is ok and the alternator is working and keeps the electric system running when the engine is on. do you know any possible solutions or common problems associated with shorts in these models?, i don't know these cars very well as it was handed down from my parents.
If you connect a 12VDC test light in line, between your + battery post & + battery cable,(cable off battery obviously) the light will stay lit brightly as long as there is a draw. Keep in mind your radio will cause some due to memory function, clock etc. Pull stereo/radio fuse to eliminate that draw, then start removing fuses, and putting them back, watch light. If it dims, or goes out, you've found the source of your current draw. I have had to resort to pulling them all,(after making notes for anything I needed to remember about where they were) to get light to go out, then re-installing one by one & watching light. When it comes on nice & bright, note which fuse slot, and pull it back out and continue on, in case of more than one draw.
