0-57003

About the 0-57003

The 0-57003 is a Voltage Tach Follower Kit Mini-Pak Plus by Reliance Electric. This circuit board is indeed mini. It features a small yellow variable resistor on the top left of the circuit board and is labeled SPD. CAL. Below the variable resistor, there are two white lines. One white line is pointing to a positive sign (+) the other white line is pointing to a negative sign (-). Below these signs is a large mustard yellow plastic box held on to the circuit board with two flat head screws. The 0-57003 has three resistors labeled R1, R2, R3. Two of the resistors are a mauvy red color and have there resistance ability printed on the outside, and the third resistor is a pale blue color with a dark red stripe, a bright red strip, a dark purple stripe, a dark brown stripe and a dark green stripe (these stripes can determine this resistors ability when the color chart and equation are used). There are also two signal style diodes. The signal style diodes are a solid black color with a gray or silver line at one end (and not the other). This line will indicate which way the energy current will flow through the component. On the side of the diode with the line, there is also a small circle on the circuit board that is drawn around the connection point. There is a single capacitor labeled C1, and a space labeled J1 with no piece connected to it.
