That way when you do have your high beams on the current from that goes to the dash switch first and if that is off the electricity cant get to the 8586 circuit to create the magnetic force to close the 3087 circuit which turns on your led lights. A relay does the same.

Does a relay need to be grounded. With our wiring harness all you need to do is cut the wire coming from the switch to the 30 prong on the relay and wire it to your high beam lead or your backup light wire. If i understand your question if the horn is grounded on one side and connected as you suggest the relay will not perform any useful function and the full current of the horn will have to come from the input. The second pin or ground is the housing which must be mounted direct to chassis or otherwise grounded. This also conveniently works for some sensors whose output is not isolated from the chassis for example many nissan cam sensors. You will usually see 3 4 and 5 prong relays.

For gigavac internal armature style relays gigavac gh1 g8 g61 g50 etc the relay base must always be grounded see fig. You can control a device load on either the power going in side of it or the ground side. Ground serves as a safety measure in circuits that are hooked up to earth ground. In which case you may as well throw out the relay. If the relay is in a metal housing it may have only one pin for the coil. It takes the incoming voltage and once grounded will send that voltage to other places.
So lets just focus on what an automotive relays is. Because it has a direct connection with earth ground it is only to sink electricity to the earth giving less risk of a fire. Joined jul 14 2004. If your relay is in a plastic housing it will have 2 pins for the coil usually reversible. If they think they dont need to be grounded you can do what another dumbass layitlow person did and was make their pump rack out of fucking wood and screw the solenoids to the wood and couldnt understand why the setup did nothing lol.

Mintz so fresh. 2 unless the voltage across the contacts is less than the specified dielectric voltage breakdown between the coil and case. Because the coils need to be grounded to the engine to keep the loop area small that means that the star point has to be the engine. The relay is a load. Just to be even more confusing.
