race car wiring question, Alternator wiring really... Options

[brant]

Hello everyone... and thanks in advance.

I'm cross posting this, so if it reads kinda "weird" that is why.

I'm trying to do a wiring harness from scratch on a race car.
Its a 1967S 2.0/6 motor....

first question: Would this be an internal or external voltage regulator on the alternator? (I'm guessing its an external, so I probably need to wire a regulator in somewhere)

second question: I'm replacing the tiny alternator warning light with a LARGE warning light.... I've seen this on other cars but they usually had a full wiring loom intact.

a)Do I need to pay attention to the wattage of the warning light bulb to get the circuit to excite?

b)should I wire a resistor in line to meet this need of a particular wattage and then wire my warning light seperate?

c) if b is true, then how would I wire the light seperate?

d) help...?

that should about cover all my questions for the next 24 hours or so... Most of the circuits (ie: fuel pump, switched ignition power, etc.) have made simple sense... but I'm struggling a bit with the alternator so thanks a ton fellas!!!!

Another possibility, you could wire a superbright LED with current-limiting resistor (typically about 470 ohms) across the existing alternator light, or replace the bulb with a power resistor around 10-20 ohms and suitable wattage. Wire the LED up somewhere easy to see, you can use small gauge wire. It will only light when the alternator fails and there's enough voltage across the stock indicator lamp (or the substitute resistor). There are also some inexpensive alarms (Sonalert, etc.) to give an audible indicator.

Here's a link to request free samples of the Sonalert parts http://www.mallory-sonalert.com/request_samples.htm

Follow-up: Check out the LSC series, small audible alarm with built-in ultrabright LED flashing indicator. That should get your attention.
