I got smoke from near the starter solenoid

The polarity was crossed for about 7 seconds before I got smoke from near the starter solenoid. I could not pin point it. I then connected the battery correctly and got no lights or anything. Checked random fuses and relay's but all seem okay. Tested the battery out of the car at 12.8 Volts. PT is still not working. Should I test the Starter Solenoid next?
