You need to check a couple things first. Some 12 volt coils require a resistor, some do not. If you look closely at your coil top, it may say "use with resistor". If you don't know what you have for a coil, I'd either get a resistor from NAPA, or buy a 12 volt coil that you know to have an internal resistor.

As for your ammeter - put a voltmeter on your battery while the engine is running. Does it show approximately 14 volts? If it does, your ammeter shouldn't peg all the way once your battery nears a full charge. If you are reading way over 14 volts, the regulator is probably ka-put in your alternator. This will cook your battery and may also be the reason why your coil gets so hot.
