The blown-fused cordless charger circuit

Field construction generators spike and fluctuate line voltage significantly during startup and tool load changes, which easily destroys sensitive digital battery microchips. Never plug expensive tool battery rapid chargers or digital equipment straight.

Stop if

The generator voltage surge just fried our rapid charger bank because it was plugged in raw. Throw a heavy-duty surge-protecting power strip box between the generator line and our tool base to absorb those dirty voltage spikes.

Watch out

Do not plug expensive tool battery rapid chargers or digital equipment straight into an uninsulated temporary line loop.

Check

Check the power/ground setup before pulling the trigger or plugging in chargers.
Use a clean direct ground or surge-protected power source as appropriate.
Watch for unstable arc, voltage surge, heat, or tool fault signs.
Stop before damaging the tool or material.
Reset the setup using the correct electrical path.
