A few weeks ago I was working on a unique construction project and was using an inverter to charge the batteries for my tools. At some point the inverter stopped working so I checked the fuse to the cigarette lighter. Fuse looked fine but I swapped it anyway and still no juice at the lighter. Before I tear the dash off and start exploring is there another fuse somewhere that might be blown? Everything else still seems to be working... anyone have this happen before? Thanks!
