0-57003

About the 0-57003

• The 0-57003 is a compact Voltage Tach Follower Kit Mini-Pak Plus circuit board manufactured by Reliance Electric.

Key Components

• Variable Resistor: A small yellow resistor labeled "SPD. CAL" is located on the top left of the board.
• Polarity Indicators: Below the variable resistor, two white lines point to positive (+) and negative (-) signs.
• Plastic Box: A large, mustard yellow plastic box is secured to the board with two flat-head screws below the polarity indicators.
• Resistors: The board contains three resistors:
  • Two mauve-red resistors with their resistance printed on them.
  • One pale blue resistor with specific color stripes (dark red, bright red, dark purple, dark brown, dark green) that indicate its resistance value.
• Diodes: Two black signal-style diodes are present, each with a gray or silver line at one end to indicate current flow direction. A small circle on the board marks the connection point on the side with the line.
• Capacitor: A single capacitor labeled "C1" is included.
• Jumper Space: There's an empty space labeled "J1" where a component could be connected.
