Cleaning and Verifying Electrical Grounds 1973 Harley Davidson Sportster XLH

Never attach a power source to your motorcycle unles you are certain the electrical grounds and connections are corrosion free and verified with a multimeter to have ZERO resistance!
I Always check the electrical system first, it would be a real shame to damage your regulator, lights, starter and charging system because you assumed corrosion or damaged wires couldn't happen to your find.
