Repair Procedure
Cut shrink tubing 1" longer than butt connector. Slide shrink tubing onto one wire end first. Insert pre-stripped wire ends into proper size butt connector and crimp connector using appropriate crimping pliers. Slide shrink tubing over butt connector, leaving 1/2" of tubing on each side of connector. Using heat gun, hair dryer, or match, heat tubing until it shrinks and adhesive oozes from each end of tubing. Connection is now waterproofed.
