Disconnect the neg bat terminal. Attach a 12V test lamp between the neg bat post and the disconnected neg cable. If you have problem the light will light up. If the light lights up leave it connected and go to the fuse block. Remove fuses one at a time until you reach one where the light goes out. This would be the ciruit with the problem. Now you can check the items that fuse protects for your problem. If you leave the doors open the interior lights will give you a false reading so you may have to remove the interior light bulbs or the fuse that protects them.

If there is a spark at the battery when you are reconnecting it after charging that means there is a short in the electrical system somewhere. This could be bad enough to drain the battery in a few days. Finding the short may be difficult but it can be narrowed down by pulling one fuse at a time and seeing if the battery still sparks, and then inspecting the system that the fuse indicates.

What could be draining the battery on a 1970 firebird?
It could be lights on in the trunk or a short someplace, your best bet would be to touch positive cable to the battery and if you get a spark something is drawing power from the battery, pull one fuse at a time and recheck the spark at the battery and when you have a fuse pulled and it finally doesn't spark when you touch the positive cable to the battery terminal you have found the circuit that your problem is in.

disconnect the battery for about 2 minutes Answer #2 Disconnecting the negative battery terminal to remove the codes will also erase any stored operating parameters from the Keep Alive Memory (KAM) and cause the engine to run rough for a period of time (several miles) while the computer re-learns the information. CAUTION: Do not disconnect the positive terminal to remove the codes from memory - if a spark should occur when reconnecting the battery, the PCM could be damaged. - Haynes Repair Manual #36071, 1994-2005 Mazda Pick-ups.
Why does the battery posts spark when you hook them up?
If you see a spark then something is on pulling power from the battery. If everything is turned off on the vehicle then you should not see any large spark. You will see a very tiny spark because the radio presets and the clock will be drawing a slight amount of power, but if the spark is very large then look for something that is pulling power. A light on somewhere or a stuck relay.
