Power and Electrical System Problems

The vehicle fails to power on: This could be caused by the main air switch tripping, a blown fuse, loose key door wiring, or loose/oxidized battery terminals. Check and reset the switch, replace the fuse, tighten or clean the battery terminals.

The charger does not charge: Possible reasons include poor contact of the charging plug, damaged charger, loose battery group wiring, or bulging battery. Check the plug, replace the charger, or repair the battery group wiring.
