Engine will not turn over? Bad starter?

Ok is the pos starter terminal the screw down one or the plug in one and im at work now cant do it till this evening. Let me clarify the starter has 2 wires one is a crimped type that plugs in the other is one that is scrwed down with a washer and bolt which do I hold the lead on?

I have a 2000 Honda Civic, the car is completely stock and I have just replaced the battery. Unfortunately, I had reversed the polartity and for a split sceond the horn blared and there was a spark before I removed the terminal. I corrected the problem, but I had to undo the negative/ground terminal and adjust so it would reach. I believe the ground has good contact, but now the car won't start. The engine won't crank or make any noise and there is absolutely no power going to anything except for the horn and the emergency lights. Did I blow a fuse? If so how do I check which fuse it is? I don't have any gauges and I don't know much about cars. Are the fuses set up so, only one would blow out, so if I were to replace that bad one everything else will work?
How do I know if it is my alternator or my starter?

I have a 2000 Honda Civic EX and when I go to start it the starter engages the flywheel but doent turn over the engine. So I went out and bought a new starter and the same thing happened down to the "T". So I went back to the store and had both starters test both were good and I took my old one and put back in. I checked the teeth on the flywheel thooses where good. I checked the flywheel to see if it was lose and it wasnt. I checked the fuses those were all good and I swapped relays back and forth under the hood and nothing changed. The charge on the battery is good and I have 12v at the starter. But what really boggles my mind is when I pop the clutch it starts right up and when I put the key to the start pos. It grinds the starter. If you got anything you can think of let me know. Thank You

I received the car this morning as a gift for my teenage son. The family member that gave it to me said it wouldnt start, had AAA tow it to my house, when I got it off the flatbed and into driveway it started no problem. After turninig it off it has yet to start again, it clicks so the starter solenoid is fine, I took out the starter and had it bench tested and it worked so took battery to be tested and it too is fine, cleaned battery terminals and cables are good, also, altenator is recently replaced. After putting everything back in and hooked up it still is doing the same thing. What can this be I am baffled it seems as if the starter wont turn over but when it was tested it came out as good.

So the starter could be bad even if it passed the bench test? And, what do I use to test the starter cables? Also, are these cables something I can replace if they are bad? Thanks! The starter solenoid clicks but the starter wont turn over bang on it but still wont turn over!

Won't start, no cranking sound, dash lights don't work, or windows. Headlights work, radio works, and the roof light works when opening the door. Dings when you put key in ignition.

Battery is good, what I did find is my 40a fuse keeps blowing. Don't know if that stops the car from starting or not.

I believe it's for the ignition starter.

It's the ignition fuse.

I changed it once but as soon as I tried to turn it over, it blew again.
