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,

Thanks, can I test the on/off function by connecting the other two pins to a 12 volt battery?

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.

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?

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?

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?

[elisapandelica]

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!

Never mentioned what to do if diode was present or not and how to identify!!!

Thank you for making a no fluff video without your history and a bunch of babble

[slevinkelevra]

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
