I accidently put the car battery charger on the opposite ends(neg and pos)?

Question

I went to get a new battery today and it still won't start. What could be the problem? The blinker oddly works though

My car is a 1994 Honda Accord

Answer 1

Well.
If you mean you had a dead battery and tried to put a charger on it backwards, you probably didn't do any damage to the car.

If you mean you bought a new battery, and hooked IT up backwards to the car, that could do some electrical damage.

If you mean that you bought a new battery, hooked it up right, but the car won't start, you need to elaborate.

Won't start HOW?

"Won't start" is pretty vague. It could be hundreds of posibilities.
Dead battery, Low battery, bad ground wire to engine, bad power wire to starter, bad power wire to battery, bad connection at battery post or terminals, blown fuse, bad key switch, bad starter, bad fuel pump, bad injectors, out of gas, neutral safety switch, seized engine, broken connecting rod, no compression, no spark, bad oil pressure switch, broken timing belt, plugged fuel filter, bad starter solenoid, bad starter, broken rotor, cracked distributor cap, Anti-theft device, water in/on engine, out of gas, vacuum leak, bad gas, bad ignition coil, blown computer, faulty cam or crank sensor ...

I could list 50 more things easiy...

When you turn the key to start it, what happens?

Could you be a little bit more specific??

1) Nothing happens?
2) You hear a "click", but nothing else?
3) You hear the starter turning, but the engine doesn't turn?
4) The starter turns the engine, but the engine won't start up?
5) The engine turns over, but very slowly.
6) the engine turns, but there's an awful banging noise?

Lastly:
What happened last time you drove it?

1) Drove home fine last night, just won't start today?
2) Was driving fine, and it just died on you?
3) You haven't driven it in a while. It's been parked in storage?

Answer 2

A little more information. you said the car will not start and you said the blinker works. however do the head lights work? Are you getting power to the radio? do any of the dash lights come on? what we need to find out is how many thing work and how many things don't. What was the condition prior to the charging of the battery? Where you charging the battery because the car would not start? was it needing to be charged because you left a door open? a light on? If everything still works, Radio, dash lights, head lights, blower motor, stuff like that, the next step would be the starter. I would also replace both the battery cables. Also if everything works be happy you didn't cook the fuse panel. If the car turns over but does not start, there is the possibility you cooked the computer. That can be costly.

Answer 3

Check to make sure all connections are nice and tight. Check to see if your alarm needs to be reset. If you dont know if it needs to be or not, disconnect the battery for 3-5 minutes, then reconnect. Check you fuses, see if any blew. You should have 2 different fuse boxes, one for the engine and one for all your other stuff, ie radio, lights... If that is ok, crank your engine, does it make ticking sounds like it's trying to start? If it doesn't then your starter needs to be replaced. That should be a good starting point for you. If none of these works, hit me up.

Answer 4

like a lot of other people have stated,you are vague on you description,of the problem.the easiest thing you could try is check your terminals,and cables for corrosion.if the are corroded,you can clean them with some baking soda,and a tooth brush.

Answer 5

you have fried something along with your alternator.

Answer 6

haha, hope their not charged, or itll blow!
