Thank you for helping a broke boy out
😅
Did the broke boy not wanna go ask a shop cause they were scared of the diag fee
You don't need to be broke to learn something new, it's called curiosity and being smart. I suppose that's why you came here no? Or perhaps you were scared of the diag fee...
so good
Thanks, can I test the on/off function by connecting the other two pins to a 12 volt battery?
Very good and important information given by you
I understood the pin 85/86
And 87/30. N c N o
Thanks a lot Sir,
👌 *Perfectly simple tutorial.* Keep making this content. _Thanks so much!_
Thanks for watching!
just because 85 & 86 have continuity- DOES NOT mean the relay is functional. Take this video down, finish it and repost. Here, let me get you started. The relay in the vid is a 5pin relay so pins 30 & 87a are connected by default. When the relay is actuated, pin 87a is disconnected and pins 30 & 87 are then connected thereby powering the load (fan motor, headlight, etc). To test the relay, when 85 & 86 completes a 12volt circuit, you should hear an audible click or 'feel the click'. In your new video- you can actually take the cover off the relay and show the relay internals moving. hope this helps.
Was wondering this, I don't know much about electronics but I know a relay has a mechanical switch function, if it's stuck open or closed wouldn't I get different readings? Does this test tell me if the relay will actually function? Thanks
Well said.
Be nice. I believe the poster is trying to help and is not attempting to deceive.
Enjoy your Sunday. I appreciate the information you shared. I have a 40 amp radiator fan relay that I am concerned about. Your post was helpful. Thanks
He could also use a 9v battery 🔋 to see if it works
thank you guys
You're welcome!
My relay tested bad and read around 830, so I got a new one and tested it which read good. I tested the old one again just for the sake of testing it again and it oddly read good. I knew I had it on the correct setting the first time, because when I got the bad reading I double checked my setting. Does this sometimes happen to relays?
You may have just has a bad contact with more resistance
I went through your video and testing 85 and 86 got nothing but with 85 and 30 read about 90 so is the relay good?
I have a 4 pron relày and with multimeter on 86 and 85 getting 0.0 is it no good? Any other way to test it? With my multimeter?
On my relay, I got 59 :) is not working properly? Good video btw
Nice video. Nissan horn not working. Good fuses and 12v on one blade plug. I tapped on horn relay and got it to work for a split second. Then nothing. Then the horn worked shortly thereafter for 1 night.
I've got a 3-blade Nissan horn relay. I can energize two blades and it clicks, but only in one direction. When I energize the two blades with a good 9v battery I measure about 4v on the output blade that goes to the horn. The 4v steadily decreases if I hold it on the 3rd blade and monitor it.
How do I confirm the relay is the issue? Thanks!
I have the same issue I replaced the relay twice and the problem continues
It looks like the problem is the horn switch and it is recommended a technician to do it because it’s close to the air bag it might get activated and you can get hurt
@miltonnegron65 yes it works sometimes and others not. Mostly not. There's a short in the clockspring harness or something like that. I'm gonna run a ground button into the cab and call it a day. All the horn cover contact does is provide relay contol ground. The horn is useless on the road anyways as every speeding or anxious jackass honks too much 😆
Never mentioned what to do if diode was present or not and how to identify!!!
Guess :/
How can I study online
Thank you for making a no fluff video without your history and a bunch of babble
man theres a residential dopr closer . ypu cannpt even comment on . there no place for reveiws and . reddits closest postvis dont buy chinease and then the name of the opener
as if it was a dont but chinease review not the multiple door opener brands
This isn't for do it yourself people. You said a bunch stuff most people don't know including myself. Very useless for most
Look it up? Everything hes saying is extremely basic + hes literally showing you how lol
