The Chardon Control Valve Diode Tester
is designed to quickly test an automobile A/C compressor 's Electronic Control Valve (ECV) or a clutch coil 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 ECV or clutch coil. This is accomplished by a Red and a Green LED to indicate the potential status when the ECV or clutch coil is correctly connected and the pushbutton is toggled.
When a connection is made to the ECV or clutch coil terminal block or by plug in cable, the unit will determine if the connection is correct and the ECV or clutch coil is good by the Red LED being ON and the meter indicating 1.5 to 3.5 VDC. If the meter reads
<1.5 VDC, reverse the leads to the terminal block. If the Red LED is off and the meter reads >3.5 VDC there is either a bad, or open, connection or the coil has an open winding. Once the Red LED is on and the meter reads 1.5 to 3.5 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 1.5 to 3.5 VDC, there is not a diode in the coil. If the Green LED goes out and the meter reads
>3.5 VDC there is a good diode in the coil.
Tester comes with 4 test leads. Two of the leads have OEM connectors
and are for control valves that are known to have diodes, one has push pins to test all control valves, and one has alligator clips for connecting to clutch coils (or control valves as needed).
