Car battery backwards

Alternator,check fusible links,

You need to take the Alternator in for a Bench check. The diodes are probably bad. Wiper switch or motor can be bad. Radio can be smoked.

For wiper motor, the contact points use a system where a derailer mechanically shifts the points to break contact. The contacts are probably fused.

That wire was probably a fuseable link which is designed to melt inside like a regular fuse.
Do you have voltage on both ends ? And are the other fuses getting power ?

if the battery is ok, you should check the starter and ignition, they may be cause your car won't start.

Click on the link for starter wiring. Not sure what's going on with your tranny? You can see in the diagram, the tranny module gets voltage from the crank position, ignition switch. You can also see the fuse, not only check the fuse, use a testlight and check voltage on fuse circuit.
Any testing, make sure functional parking brake is set and block the wheels. be safe. Safety is your responsibility.
Battery has a full charge and battery connections all good?

It sounds like you have fried your alternator ;(

was it jumped backwards or the battery installed backwards at first look for blown fuses including the large amp fuses

YOU NEED TO REPLACE THE MAIN RELAY IT MUST BE FUSED

have you checked all ofyour fuses? usually when you hook up a battery backwads you end up blowing a fuse and or fry your alternator on older modeled vehicles as there is no protection for it.
