Bluetooth Smoke Head charging contacts
Bluetooth Smoke Head equipment can experience charging issues due to faulty or corroded
charging contacts. This problem can be caused by several factors which need to be looked at
individually, but there are three main areas of corrective procedure:
• Charger base microswitch height adjustment
• Charger base contact replacement
• Smoke Head contact replacement
Ensure equipment is isolated from the mains supply before commencing work on the charger
assembly. Ensure the battery pack output terminals can NOT be ‘shorted’ together at anytime
during the Smoke Head contact replacement procedure.
Adjustment of the Microswitch
Charger base microswitch height adjustment should be set so that the microswitch is heard to
operate when the Smoke Head rubber foot is between 1-2mm from the charging base. If the
microswitch is set to operate at a too high a setting then arcing of the charging contacts will
occur. If it is set too low then it may fail to activate.
Charger base contacts
Replacement may be required if the contacts have become severely corroded. Corrosion will
occur if arcing has been taking place due to incorrect microswitch adjustment or can be a result of
the contacts becoming dirty from contaminants and debris picked up from the workshop floor.
Restricted movement of the contacts may also occur as a result of dirt or excessive heat from
arcing.
