<VV> Voltage regulator

I have suspicions that the tail lite bulb has a significantly lower
resistance than the normal idiot lite.  I think (but don't know for sure)
that this is the root of your problem.  The resistor is there only to
provide a current path in the event that the idiot lite burns out.

Subject: <VV> Voltage regulator

I'm working on a dune buggy and just got the Corvair engine running.  I
wired everything by hand (no stock harnesses) and wired a stop light bulb to
the voltage regulator.  The hot wire from the ignition switch is wired to
the bulb and the socket is grounded to the #4 terminal of the regulator
simulating the stock idiot light.  The alternator is charging fine (16 volts
pegging my meter) but I can't get the idiot light to go out.  I tried seven
regulators.  One didn't work and the other six won't put the light out.  I
checked all the wires from the alternator for continuity and they seem fine.
The battery is a brand new Optima gell cell (fully charged) so the light
should go out.  I read somewhere I might need a 20 ohm resistor parallel to
the idiot light to make the light go out.  Any comments from the electrical
geniuses here?  My knowledge of electrical stuff is water thru a pipe and
don't connect the positive to ground!
