No seriouse im so confused?!
What the hell is a relay? I pull one out to have a look at and there are 4 connectors? AAAAHHHH!

i aint exactly sure.. but i know it has something to do with powering things from your battery... not something i would muck around with.. i dont have the know how..
hahahah blake ya gumby.
a really basic relay ( 4 pin ) has a electromagnetic coil in it you power that via normally 12 volts 2 pins one for ground the other for power when you power this it energises the coil and pulls accross a plate that connects the other 2 contact pins together thus making an electrical circuit
then there are more complex relays
Hrmm.... So whats the point of a relay?
Forgive me for my ignorance, i was dropped on my head as a baby ::
yeah that we all know, but how many times ?
all sorts of reasons , to many to list but for a SPST relay in a car just to switch a high current or voltage via a smaller voltage or to safely switch the circuit inside the cabin
Gotchya, that makes sense.
Im gonna play with these parabolics some more this week
Just finnsihed the 3 stage meguires (is that how u spell it) clean, polish, wax and im exhausted
WAX ON WAX OFF!
hehe left wax right off left wax right off
Relays are good things... You can use them to turn on a separate circuit when a different circuit is running.. e.g. Say you hooked up new interior lighting and you wanted it to turn on when the door opened, you had two options, run it straight from the battery and install a switch on the door (but what a pain that would be) or you could steal the power from the interior lighting circuit...
Problem with stealing power is that it has all sorts of effects on your circuit (maybe not in this instance that much though) so if you were running something that required a heap of power, you'd suck it from the circuit you're leeching off. Not a good thing...
Simply a relay closes or opens a switch whenever it has current flowing through it. Now we can connect a relay up to our standard interior lighting circuit and run a separate circuit from the battery for our new lights without having to install switches in the door and worry about draining the standard circuit's power because we have a new circuit direct from the battery... Downside is that since it's a new circuit, it's not fused unless you fuse it yourself. It can cost more, but it's the way it should be done and you can't get around it in some instances without seriously impacting other circuits...
... Far out it's been a while since I've been here.. What happened to the forums? I'm not saying I don't like it, but hey... this is a change.. Looks like I'll have to register soon...
there are way's around that , what i do is if say i want a circuit that turns on with the ignition i find the wire that is hot when the ignition is on ( Ie the radio or somthing ) then i disable that run that through a relay and then another relay for the job i wanna do that way there is absolutly no power loss at all and you can fuse it whichever way you like.Originally Posted by Night
Ahh, nah what I meant is that you usually can't activate another circuit without using a relay without stealing the power from the former circuit... But that's a good point...
Well, looks like I did get around to registering in the end.. =P
