Locate the Fuse Box and open it. Check the 120A charging fuse. My fuse was good, you can see the copper link.

You can test the fuse with your multi-meter; set it on Resistance (Ω) and place one probe on each of the fuse retaining screws. It should read 0Ω (Ohms) as shown. It is likely this fuse is good. If not, replace it!
