well from my understanding the voltage regulator is the little black box that sits right below the horn relay on the 60-66 chevy trucks. if thats so, then yes, i do have an external voltage regulator. as for the alternator, it is a three wire, two of which go into a factory made clip that goes into the alt. terminal. the third wire is red, about 12 gauge and bolts onto the the bat. terminal on the alt.
