On the GM alternator I have running, the other two connections are labeled
as "R" and "F". Which of these is supposed to have the bulb? At the moment,
I have them both connected to ignition power, and this has been working for
quite a while. Tom also mentioned hooking up an ammeter to one of these
terminals. Will the stock ammeter work here?
