+ | ===== Testing ===== | ||
+ | |||
+ | The following procedure is a static test for basic relay operation. Passing the following test does not guarantee that the OVP relay is functioning correctly, but will accurately tell if the OVP relay is faulty. | ||
+ | |||
+ | - Apply 12V to pin 30 and ground 31 | ||
+ | - Verify with a multimeter that 30a has 12V and 87E/87L has no voltage | ||
+ | - Apply 12V to pin 15 | ||
+ | - The internal relay should click | ||
+ | - Verify with a multimeter that 87E and 87L have 12V as well as 30a. | ||
