University of South Florida (46,612 students) â Coming in as the 9th largest university in the U.S., the University of South Florida, located in Tampa, is a public institution founded in 1956. It is the second university in Florida to make the top ten list in terms of student enrollment.
Re: LED's glow when off most likely it is circuit leakage of the light itself. A fraction of a milliamp can cause an LED to glow but not put out useable light and the amount of energy used over a year is probably just a few pennies so I wouldn't put a lot of effort in trying to fix it if that is the issue.
Probe the wire or wires feeding voltage to the relay with the test light following the same procedure used on the previous step. If the light glows, there is incoming voltage. Otherwise, the relay is not receiving voltage.Check the voltage source.Switch the ignition key off. Unplug the relay from its electrical connector, making sure not to break the locking tabs on the relay. Identify the relay's power and control terminals. Some relays show a circuit diagram on top of the case to identify these terminals.f the light glows, there is incoming voltage. Otherwise, the relay is not receiving voltage.
