i have a optima red cap its about 3 months old now
new alternator replaced yesterday
i have a cobra radar that shows voltage as the car sits it will lose .1volts every 5-10 minutes
when the car runs
its charging at average
12.8-13.1
according to the radar detector
i have tried the simple stuff
rip out the trunk light thinking the merc switch was bad
disconnected the power wire leading to the back of the trunk
STILL DEAD
sooooooooooooooooooo
tomorrow im going to test with electric tester i was told to disconnect -battery cable
and use the tester to connect ground from cable to terminal i was told that there should only be a reading of 0.2-0.4
if its any higher i need to pull fuses until i find the one the causing the draw
sooo
i was wondering if anyone has any ideas of where i should start tomorrow like what things should i check first
btw the voltage is @ 8.8 in the morning

My 94 olds 88 would have a dead battery in 2 hours or less. After pulling fuses until the drain stopped, I found it to be in the trunk. I found the power antenea wasn't retracting all the way and it would look as if it were all the way down. It would continue to draw power but wouldn't hit the limit switch. I lubed it up and it works fine. The drain on the battery went away with that fix.
