## Narrative

The resistor grids on a Unit Rig MT4400 240-ton haul truck caught fire while travelling to the shovel. The operator reported smoke coming from the resistor grids safely evacuated. There was a mechanical failure of the blades on the fan used to cool the grids; this lead to a fire which was localized and contained to the rear resistor grid bank.
