We are saying that the relay acts as a amplifier, correct? In other words similar to the way a transformer with primary & secondary windings works. I never thought about this way. So a relay will amplify a low amp signal to power multiple coil packs to fire the engine?
Simple, but complicated!
Kinda. A relay takes a low amperage control signal, and uses a coil to remotely close a larger contact.
In motor control, we use low amperage/voltage to do any logic functions, then use relays, some rather large, to control the larger amperage power functions.
Theoretically, I could wire my hallway switch to turn off the entire US grid.
(Greatly simplified, but feasable)
Damnit, no WONDER California has brownouts, it's all Jeff's fault, he wired that switch.....:shocking::gurney:
but on the car end, really the amount of wiring is still done, just done in a different way, the overall complexity increase buys nothing....more parts and sub assys to fail, and more opportunity for the makers to gouge high prices for some China import....
I have a neighbor friend next door here, not so good on English...contractor, from Phillipines, his 5 y/o Ford truck 250? has a mysterious drain on the battery....pulling the main 50 amp fuse under the hood relieves the drain...but no other fuse in the lineup does.....
sometimes the drain is 250 mils, sometimes it's 2.5 AMPS, and it changes as it damn well feels like it.....can't see any lights coming on/off, and 250 mills is to high anyway....so for me to help any further we gotta go wiring manual and some damn part burried in the left bank somewhere is probably at fault....
great....ME, I"d just stick a control relay in that 50 amp circuit and hell with it, turn it on and off with the switch on the dash.....or reroute the damn ignition to close the contacts.....get burned out with chasing that stupid shit....old cars ran the freeking same and were SO much simpler....
still running a wire, wether it's 22 ga or 12 ga, still more BS parts to sell....
customers with older vehicles are getting ready to take it up the ass but GOOD with all this crap....bad as special tool # J 1054326.5, and if you don't have that updated .5 on the end, sorry, but you need it and it's 500 bux off the Snap On truck......
Like TORX, get OVER it already, it's a freeking BOLT, stick a HEX cap on it, and get on down the road already....but NO, look at the bunch of sizes in that TORX set....can't tell one from another, when about 5 outta the set could cover the whole damn gammit of what they trying to accomplish....
private industry making work just like the WPA in the 30's....dig a hole, fill it up everyone gets paid, and the wheel fell off....
