Description

Overview

Replacement control board for Dayi 2106 and 6802 brushless electric wrenches, combining the speed switch with the motor drive circuit. Order by wire count and capacitor value: 8-wire 220UF 35V, 9-wire 330UF 35V, or a switch version at 36V or 42V.

Specifications

  • Fits: Dayi 2106 and 6802 brushless wrenches
  • 8-wire board: 220UF 35V capacitor
  • 9-wire board: 330UF 35V capacitor
  • Switch versions: 8-wire 36V, 9-wire 42V
  • Type: speed switch and drive board

Purpose

A wrench that stutters, skips speeds or dies under load usually fails at the board, not the motor. Matching wire count and capacitor value keeps the repair electrically correct.

Applications

  • Dayi 2106 board replacement
  • Dayi 6802 board replacement
  • Speed and trigger fault repair
  • Brushless wrench rebuilds
  • Spare boards for the shelf

How to Use

  1. Pull the battery and let the tool cool.
  2. Count the wires and read the capacitor marking on the old board.
  3. Note the lead positions, then desolder the battery, motor and switch.
  4. Fit the new board and check every joint for bridges before assembly.
  5. Caution: the 36V and 42V switch versions do not interchange. Match the rating to the pack voltage.
