Welding Work (Overload Protection Of Control Units)

When performing welding work on installed control units, to avoid any defects in the electronic control units, observe the following steps:

• Observe instructions for disconnecting and connecting battery. See Disconnecting And Connecting Battery  .
• Detach terminal of battery negative lead from car battery and second battery if fitted. Cover negative terminal posts.
• If welding is to be performed near the battery/batteries, first remove battery/batteries from vehicle (flying sparks - combustion of explosive gas).
• Fit return clamp on welding unit as close as possible to welding point (maximum distance approx. 1 m).
• Never connect return clamp to ground pin on body which has ground wires attached!
