The alternator fail light bulb has about 40-60 ohms of resistance depending on the bulb you use. If you use the bulb instead of the resistor, it will work also.
The alternator/bracketry I'm using came out of a 91 firebird. It has a 105 amp alternator. I wired it up using a Gm alternator wiring diagram that I found on the net. I have no place for the alternator bulb in my 57, so I just zip tied the bulb and socket to the wiring harness under the dash.
The bulb is only on with the ignition on and the engine not running.
It doesn't get hot enough when it's lit to damage anything, and in addition, from the time you put the key in the ignition to starting is just a second or two anyway.
If you wire in an alternator, and can't find wire large enough, you can use two 10 gage wires off the alternator to the battery terminal on the starter, or the fuse box large battery lug.
You do not want to fuse this wire.
