My 1997 grand cherokee has a draw that drains my battery every 3 days, grounding from the neg. post to the neg ground with a test light goes on brite, pulled all the fuses and relays still have draw?????

OK this should be simple to locate - you will need a ammeter. Disconnect the negative lead on the battery. Connect the ammeter in series between the disconnect lead and the battery terminal and with everything off take a note of the current draw. Switch on an interior and note the extra current drawn. With everything off (door closed etc) check the current. Ordinarily this should be very low, perhaps just enough to keep the clock running and the anti theft system active. Open the fuse box lid and remove and replace each fuse in turn noting any change to the current reading. Each fuse corresponds to an electrical circuit and by a process of elimination you will hit on the culprit circuit, the one drawing current and killing the charge in the battery. Most times the guilty party is a glove box light that fails to go off when the glove box lid is closed, the problem here is that when the lid is closed you cannot see if it switches off as it should. If it is a short you will have to locate the break in the insulation and fix this. In the mean time you can assess if you can run the car safely without the offending circuit having its fuse left in, better to have car that starts than say having a sun roof that is temporarily out of action
