How can you tell if a relay is open or closed?
Leave the multimeter on ohms or continuity. Touch the leads across the switch pins. A normally open relay should read open or OL. Energize the electromagnet coil with a 9-12V battery across the pins. The relay should make an audible “click” as the electromagnet coil energizes and closes the switch.

How do you find the ignition relay on a car?
When you locate the fuse box, open it and find the mapping on top of its lid. The key will tell you the exact position of the ignition relay as well as other relays and fuses. Once you have located the relay, gently pull on it to remove it from the fuse box. The relay looks like a rectangular block and is hard to miss.
What causes a car relay to short circuit?
If the relay is short-circuiting you may drive again only for the car to stall again. In the fuse box, you will notice the relay plus other fuses. Dirt and contaminants find their way inside the fuse box and destroy the fuses. When this happens you may have a damaged relay.

Identify a pair of pins that separate when power is applied to the coil. One of those pins is a pole. It will establish a new connection with one of the stand alone pins. And that pin is the normally-open contact. There are countless different types of relays – too many to consider here.
How do you find the pins on a relay?
All they do is make and break sets of mechanical contacts. With careful observation – and a little logical thought – you can work out exactly what’s happening inside the case. Start by finding the two pins connected to the relay coil. You can do this with your multimeter. The coil pins will be the only pair that exhibit a resistance.
How can you tell the resistance of a relay coil?
With careful observation – and a little logical thought – you can work out exactly what’s happening inside the case. Start by finding the two pins connected to the relay coil. You can do this with your multimeter. The coil pins will be the only pair that exhibit a resistance. It’s likely to be somewhere between about 50Ω and 1000Ω.
What is the resistance of a DC relay?
It’s likely to be somewhere between about 50Ω and 1000Ω. Low voltage DC relay coils obeys Ohm’s Law. That is: – Current = Voltage ÷ Resistance. For example – the standard version of the 12v Omron G2E relay – has a coil resistance of 330Ω. So the current through the coil is 12v ÷ 330Ω = 36mA.
