1996 z28 mystery battery drain - any leads?
I have a 1996 z28 with 42k miles on it. Suddenly has a battery drain that will discharge the battery in about 24hrs to the point where the car won't start. Put a charge on it for a few minutes and the car starts right up. Alternator putting out 14.7 volts while charging the battery.
looking for leads. I have a mustang which has a factory service notice about air conditioner relays that remain on even when the car is off and will cause a battery drain...sure enough my mustang has the issue..and we just have to make sure we turn off the heater/ac, else the battery drains.
So I'm wondering if there are phantom drains in the 1996 camaro. I read that some folks think the alarm can be a cause of a drain so after charging it today, I'll lock the car up with out setting on the alarm and see if it starts tommorrow.
Any other leads would be greatly appreciated.
Battery is six months old or less.

Turn everything off including the ignition key. Disconnect one of the cables from the battery and insert an Ohm meter between the battery cable and the battery terminal. You should be reading no more than 0.5-0.7 amp. If the reading is higher start removing fuses, one at a time, and keep looking at the meter. The fuse that will make the reading drop is the fuse feeding the circuit causing the drain. Now see what is connected to that circuit and find the culprit.

probably because there isn't some magical battery drain problem specific to a 96 z28...do what pete said...that should help. otherwise you're looking for lights that stay on. took me and my father 2 months to figure out why my battery kept drainin on my old s-10...finally we realized the glove box light stayed on. how do you honestly spot that? lol

You did not state how old the battery was??? Batteries do not last forever. If it is over three years old start thinking about a replacement.

On several occasions over the past ( I'm not revealing how many years), I've unknowingly installed a bad part. What happens is that you will assume the installed part is good, and since the "problem" isn't fixed, you move on trying other things. As you get more experience, you begin to trust in your abilities and also trust "theory". When you begin to 2nd guess yourself is when you begin to, as my Dad used to say, "chase your own tail".
