Re: battey sparks when hooking positive up
You should always disconnect the neg. side of the battery when you disconnect. This is prevent a power surge to the ECM. The sparks you find is it's detecting something is on. It could be as small as the radio constant (memory).
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Unhook the battery on the positive side. Use a test light and hook it to the positive battery post,and touch the unhooked positive cable. If you have a draw,it will light up. The best way to narrow it down from there,is to start pulling fuses..one at a time..,untill the test light goes out.Then check the manual to see whatt that fuse runs power to,and go from there.
It's on the passenger side, you lift up the bench (bottom) after you push back on the bottom front of the seat-do one side at a time, unhook it from the bottom front first, after you get both sides unhooked it just lifts up and off. then it is just a matter of unbolting the hold down and the battery clamps-do the positive post first, then the negative side. when installing, hook up the positive side first, then the negative side-clean those battery terminals inside and out with a wire brush or emory cloth, modern cars need really good electrical connections.
sounds like you are on the right track. Hook the jumper cables up to the dead car first. The red cable should go to the jumper terminal as you mentioned and a good place to hook up the black cable is the bolts on the strut tower.
then with the other car running hook up the red lead to the cars positive battery cable and then the negative to a good ground. Let the two cars sit for about 5 to ten minutes to give the dead battery a chance to charge.
Once the dead car is started let it idle with the lights turned off for at least 45 minute to an hour or drive it for the same amount of time with the light on (I assume you will be driving in the dark) or if its day time drive it for 30 to 40 minutes with the lights off. This should be enough time for the alternator to charge the dead battery.
Either have a bad battery, sometimes they go bad and the symptom is a "self" discharge that will run it down in a few days.. or. You have something inside the car that's running it down.
The way to check is to unhook the battery for the time that its down and see if the battery is dead when you return. If the battery goes flat unhooked, you have a bad battery. If the battey holds its charge while unhooked you have a drain from the car.
Your car I think was bad about one of the cooling fan relays sticking "on". Just something to be aware of.
the wires on the positive post are the large cable goes to the starter, one of the smaller wires goes to the chargingcircuit and the other goes to the fuse/relay power center, now how to check for a draw on your battery, first you need to remove the battery and have it charged you can take it to auto zone and they will charge it for free. after you have the battery charged hook up the negative battery cable but do not hook up the positive cable, make sure every thing is turned off and all doors and trunk are closed, then take a 12volt test light and hook it between the positive battery post and the positive battery cable if the test light lights up you have a draw, if it lights start pulling fuses one at a time till the light goes out. when you find the fuse that turns the light out you found the circuit that is drawing on the battery. now i cant tell you what in that circuit is drawing you will have to come back on and tell us what fuse it is and we can look up what all is on that circuit, if the light stays on after all fuses have been tested unhook the alternator if the light goes out you got a bad alternator......GOOD LUCK
Yes you can slowly charge the battery in the truck,but make sure the battery is disconnected first,make sure you unhook the neg first then the positive,and when reinstalling it hook the positive back up first the the negative you want absolutely no sparks.I have also had to jump start these vehicles at that battery and had the owners drive them 50+ miles and they were fine after that.For those cars it is recommended that they have to be driven or started for a length of time every day or two.I would call your local Toyota dealer and find out for sure.
