Full model list at the end of this description.

⚙️ Key Features

• Genuine alternator brush service component
• For compatible 14V 115A charging units
• Restores rotor field-current contact
• Brush set only; regulator and complete alternator are separate
• Engine type: 14-volt internally regulated alternator, model dependent

🔌 Function

Maintains sliding electrical contact with the rotor slip rings so the voltage regulator can control rotor field current and alternator output.

⚠️ Common Signs of Failure

• Intermittent or absent charging
• Battery light flickering with vibration or engine speed
• Brushes worn to or below service limit
• Arcing, burnt brush leads or heat-damaged holder
• Uneven or deeply grooved rotor slip rings

🛠️ Service Notes

• This is specifically an alternator brush set for slip-ring contact — three of the brush sets listed under this item type are actually starter-motor sets for a commutator, so do not cross-order between them; check the alternator housing marking and output rating (14V 115A) before ordering
• Confirm the alternator manufacturer and housing number stamped on the unit itself, since this set does not fit every 14V alternator across the wide D-series engine list documented against it
