The Chardon Control Valve Diode Tester is designed to quickly test an Automobile A/C Compressors

 Electronic Control Valve for an embedded Diode. The test has two indicators that are used to identify 

a diode being present and confirming that it is present in the Control Valve. This is accomplished by a

Red and a Green LED
 to indicate the potential status when the Control Valve is correctly connected and

the pushbutton is toggled.


When a connection is made to the Control Valve terminal block or by plug in cable, the unit will determine

 if the connection is correct and the coil is good by the Red LED being ON and the meter indicating 2 to

3 VDC.
 If the meter reads 0 to 1 VDC, reverse the leads to the terminal block. If the meter reads>4 VDC there

either a bad, or open,
 connection or the coil has an open winding. Once the Red LED is on and the meter

reads 2 to 3 VDC, press the pushbutton and observe
 if the Red LED goes off. The Red LED should be off. If

the Green LED is on
 and the meter reads 2 to 3 VDC, there is not a diode in the coil. If the Green LED goes

out and the meter reads>4 VDC
 there is a good diode in the coil.
