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.

How can you tell if a relay has a blown fuse?
If voltage is able to flow through that side of the relay, move on to the 87 connection point and determine if battery voltage is present there. If it isn’t, that also suggests a blown fuse or circuit breaker. Checking the connection points in the fuse box with a multimeter will confirm if battery voltage is available at the relay terminals.
How do you check for a faulty relay?
The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).
Where are the power pins on a relay?
Pins 85 and 86 are on the control side of the relay. Power from the switch flows into the relay at pin 85 and out to a chassis ground from pin 86, making a complete circuit that activates the relay’s electromagnet. The magnet closes the second independent circuit within the relay that runs between pin 87 and 30.

The positioning and polarity of relays and fuses should be printed on the inside of the relay box or fuse box cover.
What happens when a fuse melts in a panel?
These are the fuses, which contain a filament that melts when it experiences voltage overload, and then cuts off electrical power to the circuit. When this happens, the fuse must be discarded and a new one put in. Should You Upgrade a Fuse Box to an Electrical Panel?
