Automotive technician for 8 years, dealerships and independent shops. Now I'm a heavy equipment mechanic/welder at Wyodak Coal Mine. I do everything from simple 12v electrical diagnosis to frame repair to engine rebuilds. We have 150-240 ton Komatsu haul trucks; Tamrock/Drilltech drills; Cat scrapers, loaders, dozers and blades, and P&H shovels. I pretty much have to do everything on everything. It's a very interesting job at times, other times it just plain sucks...
