get power (current) inside the steering whell, through the horn button.
hello forum. i want to pass power, inside my sterring wheel, to do some stuff (in our case, asuming to power some LED's is ok). the problem is, that since my car is prety old, there are only two cables going inside my sterring wheel. the cables that power the horn. so i have to make due, with them.
here is what I THINK the schemantics of my horn look like :
meaning, that , when you press the horn, the +12v rail that goes to the relay, closes, the relay energizes, and allowes current to go to the actual horn.
now , what i want to do is something like this :
meaning, i still keep the horn button, only with the addition, that is bypassed, with a rail that poweres some LED's. becouse the voltage drop of the LED's in my case is about 12v, the relay ALWAYS get cureent (not only when the button is pressed), but its about 1v, so it dosent energize.
ALL fine and good and tested up to now, and it works prety good, with one exception.
when i turn on the car, the LED's turn on, and no horn sound. BUT when i press the horn button, the horn starts hitting, BUT it dosent stop when i realise the button...
anyone has any idea what i have done wrong??
or if there is a better way to pass power inside the wheel, at all??
thanks in advance!!
