engine wont turn over

i have a 97 shinoda boss and the fan recently fried....after it did everyday the batt was weaker and weaker now all it does is click repeatedly when i turn the key....had batt and alt tested both are good...figure the batt problem was the bad fan constantly pullin on the batt.....still cant figure out why it wont start...unless i push it off the it runs fine..

Something is draining the battery. With a multimeter to measure mini-amps (you have to remove one battery cable and attach the meter between the cable and the terminal), remove the fuses one at a time until you get no draw. Electrical gremlins are a realy pain!!

Good luck....
