hum, could have knocked out the volt reg, rare to harm the TTale units but possible. Remove the batts and test_charge separately. The older units w_o processors are rare to have this happen UNlESS the welder strikes a wire in the harness electrical system or the welder ground was placed in a really dumb location. It is always good practice to disconnect batteries before welding on any vehicle. It is better practice to tell father it must be the Deere Fairies that struck the combine rather than telling him it was his wrong doing.
