Have had some trouble identifying the two small terminals for light and sensor, but their use is optional. Nice product, exact replacement for my old alternator.
Does it have an external or internal regulator Installed this on my 66 chevelle. I bought this after I rewired it to eliminate the external voltage regulator. It has an internal regulator. does it come with a pulley as shown? Yes it does. does it come with a pulley? Yes the one we bought had a pulley. I would double check on the Powermaster webpage to see what type of pulley should come with the part number.
