I was jumping my 1995 Geo Prizm and my friend put battery posts backwards on his battery now my car has no dash lights nothing can you tell me what this is

You blew a Fuse!!! THAT'S WHY THEY recomend to put the black negative wire cable to the engine not the battery the ECU could be compromise if you dont, lucky for you its just the fuse or the wheel that makes it brighter and turns your interior courtesy lights on, .good luck.

How do I remove the main fuse in an 02 Suzuki Grand Vitari XL7?

Sparks do fly, the last connection on the cables is ground
to a metal , on engine not battery,
this will make a small, spark. all do, that. done right.
but if done backwards, a huge spark with the 2 batteries bucking each other, and damage will happen.!
yes you may blow the main fuses,
my guess you blew the 80amp fuse in the main fuse box under hood.
did you put the new battery in correctly Plus to PLUS
and NEG to NEG lugs, if not, BOOM AGAIN.
open hood,
fuse 1, if it ok, then the others fuse to the right blew.
when fuse 1 blows, all things die. zero power to anything in car
including head lights, (head lights are always the first check)

Battery placed in backwards

You probably blew a main fuse or circuit breaker. I believe your fuse box is on the driver side under the hood. Check your owners manual for fuse I.D. Then check the main fuses.

Hooked battery up backwards

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.

The electrical system fails while driving

I would say you have toasted your main fuse board and the only true fix is to replace it GOOD LUCK

Hooked battery up backwards

under th hood there is a fuse box by the battery inside of there you will find an odd looking fuse, it should be 80 amps if I remember correctly this the fuse that is probably burnt out as it is there to protect your altenator. to help locate this fuse it is usually held in with two screws, ( it is not like the ones that push in ).
hope this helps you and I hope that you will take th time to rate this response .
