== == A loose battery cable will allow the alternator to run 'open circuit'. This puts the engine computer and other equipment under alot of strain from having to deal with very poor quality power. (essentially pulsed dc with some high voltage spikes and varying with engine RPM) The battery greatly stabilizes this dirty power. Assuming you didn't fry your engine computer, I'd try just resetting it. Disconnect the negative battery cable. Wait 5 minutes. Hook it back up. Try to start it. Beware of doing this if you have an anti-theft radio or an ignition key with a chip in it. You'll likely end up needing the dealer. The harder the copper wire presses the more energy will flow through it.

Its called a parasitic draw. Any electrical component in the vehicle could cause it. To test for a draw, pull the negative battery cable and use a meter to measure amperage between the battery terminal and cable. The reading should usually be below 50mA or <.050 amps.

Do you hook up the positive or negative wire first on a battery?

Always hook up the red or positive cable first, otherwise you could cause a short between the battery and the car through your wrench. Ths of course could cause an explosion or other problems. The black or negative cable goes straight to the engine and the car's frame, so your wrench can touch the frame when you are tightening the cable end on the battery with no worry.

Do you reconnect the ground or positive cables when installing a car battery?

Safe practice directs that when connecting battery cables to the battery, the positive cable should beattached first, and then the negative cable last. In disconnecting battery cables, safe practice directs cable order in the reverse, I.E., the negative cable is disconnected first, and and the positive cable last. The reason for this safety procedure is that IF the ground cable is attached first, then when using a metallic wrench to tighten the positive cable clamp, and IF the wrench in contact with the positive terminal clamp were to come in contact with any grounded metal of the vehicle, then a tremendous short circuit would occur. A massive short circuit results in massive arcing [fireball] which can severely burn a person, damage the battery [or cause it to explode], damage the vehicle electrical system, or worse, cause the vehicle to catch on fire. Always connect the negative cable last, and disconnect the negative cable first!
