Jeff,
Installing a battery backwards is BAD business....  there's a good chance that
you have fried one or more of the following:

The diodes in your battery isolator.
The diodes in your alternator.
Your voltage regulator.

Can also damage engine ECU and stereo and who knows what else.
Does the alternator get hot when the engine is NOT running? That's
a sign that one or more output diodes are popped, and the battery
is discharging through the alternator windings.

Good luck...
