91 toyota pickup battery installed backwards need some advice
Hi i have a 1991 toyota pickup 2wd 3.0 6 cylinder and i recently installed the battery wrong. positive on negative and negative on positive ( reversed polarity) I saw some sparks on the battery terminal but no smoke coming from anywhere. I checked the fuses and sure enough i blew the 80 amp alt fuse and the 15 efi which i have replaced no problem. I also checked the fuse panel on driver side interior and they all look good. now with the battery hooked up correctly i put my key in and all i get is a ignition buzz to let me know the key is in and the door open, i get the instrument panel to light up temporarily but once i turn the key to start i get nothing and the electronics stop working, the stereo does not work either nor the ac blower fan, i am able to use the dome light still which is not very bright but still working. im not sure where to go from here. does this sound like a relay? how can i tell? i am new to electrical problems so any tips would be appreciated. thank you

Like ksti says^^^
Next only to our senses, the multi-meter is the most important electrical troubleshooting tool. Electrical troubleshooting without one is like going to war without ammo.
A problem well-stated is a problem almost solved.
It would also help if you organized your problem description:
Clearly list all systems that work (i.e., tail lights work? Headlights work? Dash backlight work?):
1)
2)
3)

Clearly list all systems that do not work:
1)
2)
3)

The battery checks out at about 12.6 volts i went and got a new one just incase.
i had the battery connected backwards for probably about 10 minutes before i realized it and yes i tried to start the vehicle a couple times like that.
current situation.....
headlights are working
dome light working
i get ignition sound to let me know key is in when door open
When i put the key in and turn on electronics....
blower fan will turn on
stereo is working after i replaced 10 amp in the back of it
cigarette lighter is working
when i turn key to turn start engine blower fan will die all electronics cut out and all i hear is a slight whining sound
The starter? I should also mention before i screwed everything up with reversing the polaritys. The reason i bought a new battery is because truck wouldnt start just made a rapid click sound
also another update truck just started up once and then i turned it off to see if i could start it again but no just a slight whiny sound

the battery was bought at walmart i took it back and exchanged it just incase it was bad this was before i bought a multimeter.
but i do have a final update for this, hooking up the battery wrong blew my fuses .and the whiny and click sound i heard was due to corrosion on my battery terminal connectors. i had cleaned them with a wire brush but it apparently was not enough. there was only a small amount of juice making it through but not enough to start the truck and i had to replace them now it starts right up. so case closed. thanks to everyone that jumped on to help
