A sacrificial anode assembly is insertable into a metal water storage tank to inhibit corrosion thereof and includes a cylindrical metal anode member having an end retained within a cylindrical plastic insulating sleeve which, in turn, is captively retained within a metal cap portion of the assembly. To regulate the amount of electrical current generated by the assembly during use thereof, a barrel-shaped resistor is supported within the assembly and interconnected between its anode and cap portions. The insulating sleeve has a generally U-shaped groove formed in a closed end thereof, with one leg of the groove extending diametrically across a central opening in the sleeve end that receives a core wire portion of the anode member, and the other groove leg extending generally chordwise relative to the sleeve end. The resistor body is received within the chordwise groove leg, and a lead wire of the resistor is extended through the curved and diametrically extending groove portions and spot welded to the core wire portion received in the central sleeve end opening. The configuration of the groove and the relative orientation of the resistor and sleeve opening causes the bent lead wire to form a resilient connection between the spot weld and the resistor body, thereby substantially reducing vibrational fatigue stress on the spot weld during shipping and handling of a tank having the anode assembly operatively installed thereon.
