[Roadsters] Delco 10SI Alternator question

[Brian St. Jacques]

Is this why there is often a resistor or resistor wire in parallel with
the bulb? Anyone know how much resistance is typically used there?

Matt,

I have a GM alternator in Mr. Hyde.  If I remember correctly the idiot
light is the excitation lead.  I played with several bulbs in this
circuit and found that some caused the alternator to require a lot of
revs before it would come to life.  I finally ended up with a #53 bulb,
which requires a few RPM to start charging the battery, but it is a good
compromise for me.
