[FC] "Gen" light

[Andy .]

One alternative option would be to just upgrade to an internally regulated alternator from a 1973-1982 Chevrolet/GM car or truck (10si).  Would need to swap half the case and pulley (not hard).  If my budget allowed I would probably go for the brand new Remy unit from Advance Auto for $75 exchange ($85 outright), Lifetime warranty,  order online and save 35-40% with a coupon code found here:

and pick up in store (some stores in my area stock the new one)  Or you could get the reman one for about $20 using the coupon code.  The correct new pigtail is about $3.  The "automotive expert" behind the counter usually isn't at all concerned with what the core return is (only $10 anyway for these very common units).
 
Or you may have a local shop you like build you one as well.
 
One warning - the factory support bracket does not bolt up to the internally regulated case so you either leave it off or fabricate a solution.  I think most people just do without it and are ok.
 
Just a thought.  
 
As always YMMV.  But I did want to share those Advance Auto Parts codes with the group.  Saving 40% brings their prices about inline with my favorite online autoparts retailer www.rockauto.com  5% discount codes for them are always available with a quick google search.  Usually covers half the shipping or so and there is no sales tax :)

> When the red light is coming on, my after-market voltmeter reads 10 volts. Then as revs climb the light goes out at about 2200 RPM. Even when running at highway speed the voltage never exceeds 12 V. when it is in this condition. When the truck works correctly, the Voltmeter reads 14 V at idle and slightly higher as RPM's build.Tim W '61 Rampy 140 4 spd W /alternator
