Alternator resistance

[C5813@aol.com]

To those electrical types out there who've ever considered converting their
Tiger to an alternator: what is that 15 ohm resistor (in parallel with the
ignition light) for? If the designers wanted to limit the current flow
through the light I would have expected them to use a series resistor. (I'm
trying to figure out if the extra ohm in my 16 ohm resistor will blow up my
car.)
