Wrench while on the positive battery terminal hit frame and I lost all power?

My wrench while on the positive battery terminal hit frame and I lost all power. So, I checked the fuses the only fuse I found blown was I went to get another fuse no longer than a minute and the power was back on in the form of interior lights the would not turn off so I tried to crank car and something sounded like metal on metal starter I think which I've had no trouble with then nothing all power completely out I checked with multi meter 0 I went to charge it, it had only 10.45 I removed it placed on charge until charged checked fuses again all good put batt in and interior lights came on I attempted to crank it same noise but more sickly sounding but no start almost like not getting fuel quickly turned off key because I see smoke from passenger side off the motor but could not see where it was coming from I tested battery as the power seemed to fade so in just 4 minutes power dropped to 10.35 and no fuses blown I searched for the fusible link but could not locate one so I tested all wires coming off batt by attaching my leads to fuse box and the other to batt on each wire all had continuity I'm at a loss so ruled out if one of those was fusible link. I failed to mention the fuse blown that one time was the left heated seat fuse 10 amp I don't have heated seats.
