- Today we're going over the steps on how to locate, remove and test the starter relay. Testing the starter is simple and straight forward.
A starter relay is a small electrical device found in the starting circuit of high-current motors. The relay is essentially a remote switch that controls a high-current circuit. In motor vehicles, a starter relay uses the small ignition switch current to close the much heavy-duty starter circuit. It essentially comprises a magnetic core with a wire wound around it. On one end of the core is an armature or plunger that closes contacts to work a switch.

I wanted to test my starter relay today and watched a bunch of clips on YT. This one is the best I have seen. Simple, step by step from beginning to end, very methodical. A one time explanation and one time understanding.
Can’t thank you enough for taking the time to make these vids, walk viewers through in simple terms how to do all this! Truly a life saver as I try my best to fumble through trying to diagnose and fix my vehicle with only basic knowledge of mechanics 😂 I really appreciate you, Sir!!
Relays usually have markings on top denoting pin functions.
A "ww" represents a resistive load - that of the relay's coil. A "NO" is normally open contacts...a "NC" being normally closed.
Hope this helps.
Many, many thanks for your well made video on how to use meters to check electrical parts. I really appreciate that. You went even beyond ... for us to lose the fear of doing something wrong. Many regards from Florida

Thank you, nice and easy and thorough and complete. I was going to buy a relay for $50 not knowing if it was good or bad. But now I can test it and see if it is good or bad.
With Denso 4 prong relays the copper prongs are the ones that connect to components, or load (terminals 87 & 30)& usually they're a little larger as well, so the ones you connect to power will be the smaller, less coppery colored ones..#s 85&86
I say it all the time you learn something new everyday no matter how old you are good job thank you
Thank you. Appreciate the feedback.!
Thanks for step by step making it simple while others go fast in explaining and we ended up with confused ❤👍
Thank you so much for your easy to follow and understand video as I’m having just such a problem on my 1996 FourWinds, Class A, motorhome. I’m hoping to learn some basics before a mechanic starts replacing one part after another as I’m a senior citizen female. I believe I’ve an honest mechanic but I feel better having some knowledge of how things work even though I’m not comfortable doing any such repairs. I did opt to pick up (2) new batteries as the deep cycle marine battery was 12 years old and wasn’t charging on a trickle charger. The engine battery was a 5 year battery with only 7 months left on it’s warranty and I don’t want to get stuck somewhere along my travels. So those have been installed but still no turn over. I asked about the possibility of the ignition switch but after he attempted several tries of starting and removing the doghouse cover he next went to the starter relay. Just waiting for part to be ordered in the morning and installed. But before he installs the new part I’ll ask him to test the old one.
congratulations on the fine job you do explaining things.
I actually searched for a non-working snowmobile electric starter and got this video ! I actually pulled out nearly the same relay from my sled's electric starter that wasn't working ! I just ordred the relay hopefully it will work and turn over !
Love that you took the time to be detailed and show step by step. Keep up the great videos. Used your channel for multiple things now.
Thanks a million for showing the trim removal! So many other vides show the relay with the trim already removed.
Good video bro! Saved me time. I used stranded copper speaker wire to wire it to my car battery. Super ghetto but i got it done. Relay is functional, and has continuity when live. I've also tested my motorcycle relay months ago before this video, but it was way more straight forward. the power and ground were obvious, this relay it wasn't. relays good, my starter motor isn't. Need a new one.
rofl hardest part was when i realized.. (bulky jumper cables) aren't the best way to put power on it.. haha, so i swapped to speaker wire. worked will, i tied it on and it was functional.
Keep up the great work! We appreciate it.
Thank you! Appreciate the feedback
You are really good at explaining. Well done.
Thx. Great vid. I was starting to work on my 2010 Sequoia 5.7L and that will take me days. So I found your vid and did what you said. My starter relay is bad. You saved me $200+ and days of labor. Thx. again.

What symptoms was it showing ?
Great video mate, I do lots of mechanical work, but know very little about electronics, this may prove to be an invaluable piece of info for me. Thank you!
As always, a thorough, very well-organized, very well presented tutorial.

Thank you for taking you’re time on this video
Thanks man for making a good video 👍 no ramble ... you got right to the point ...I fixed my issue within 10 mins I was back rolling again
Glad it helped
Can this affect modern 2017 till date car also?
What if it cranks on a push start but it's not your battery or starter ? Your explanations are nicely detailed btw.
Check the fuel pump/lines, spark plugs and ignition. Cars need combustion to operate and most times you’ll have a clogged fuel pump
Wow this was so explainable and easy to understand, Thank you.
👍 GREAT , THANKS, NEED TO BUY THE TOOLS, TRIM REMOVER & 12 VOLTS DEVICE .
Dude - this was a great video. Yes, have the problem you outlined and I feel confident I know how to do the test.
One word ultimate explanation
Thanks for the info. Its a great help for me as novice in the Automotive.
It enhances my knowledge on this field of industry.
Overall good video, however, towards the end, you zoomed into the prongs on the relay itself, and you should have zoomed in on the tester to show what will happen to the display when you have them touching the correct ends... what does the LCD do? Overall, good, but that could have really solidified the explanation.
Excellent!! How do you check using the battery?
Good video. Not too long and to the point. 👍
Ah, a nerd. Thank you very much for this video
When checking for continuity on the horizontal prongs, as a final test, can you also check them with either a test light or the multi meter set at 12 volts?
Excellent explanation, I learned a lot. Thanks you so much.
Excellent video thank you!! 👍
Life saver man this fixed my problem. I replaced my battery for nothing but at least its new now lol
Thanks for the information. I will check it out now.
Thank you!
You know how to teach and make a video. Great A+++
Thanks A lot for the info, did it and my mdx started right up. This was Supremely helpful
Thank you for the useful video.
Nice concise presentation. Thanks.
Glad it was helpful!
The best video for the problem
Very easy to understand. Thanks a lot
Great video clear instructions very helpful
Thank you
Nice job my friend!
GREAT VIDEO DUDE THANK YOU FOR SHARING, Rock on
Rock on!
Thank you. Going to check started relay on my 1981 BMW R80/GS.
Well done mate good explanation.
I agree with the guys very good video. Thanks alot
So when this relay goes out is it permanently shot or maybe sometimes works sometimes don't ?😂. My car it's random no start but🤔 I do hear a single click from I think the ignition switch Great video, and much appreciated .🙂
Video Start 5:58 thanks
Learn alot thanks for the video
smart presentation
do i have to disconnect the battery to remove the starter relay? is it required?
That's what I call a PERFECT VIDEO.
This shows when it is working, but if it is going bad, the relay would be giving continuity but be jumping in ohms up and down correct? Therefore in need to be replaced
Thank you.
Thank you very much for the video! I tested the ignition coil and starter relay and both show (sound) continuity but neither click. Could this be because they are both stuck in the closed position?
I just wanna say thank u so much ,,, boom my realay was fucked ,,, wouldn’t av none this if it wasn’t for your brilliant explanation of testing ,,, thank u 🙏 Adam
Glad it helped!
Thanks for the video. If you had an intermittent no crank fault and carried out this check, would it only show a fault some of the time? My 2008 Mercedes CLK fails to send power to the starter motor occasionally and I think it's either this relay or the electronic ignition switch but because the fault comes and goes as it pleases I'm not sure how to test. Any ideas?
thank you brother
Very informative
Great job indeed thanks a lot 🛠
Great video !!!
Excellent video!!! Can you write the tools you use in this video?? Please!! Thank you for this video!!
He listed most of the tools in the video description but not the battery pack ( as of 2022-09-15).
Nice tutorial sir...
10/10 video! Very well done!
Thanks so much!
Nice work man 👍🏿😘
Very useful video. Like!!
When I push my ignition start button I hear a click & not a cranking noise it is intermittent. The car may start after pushing button once or 5 times or anything in between. Do you think it is the starter relay?
Same issue here, did you get it resolved?
Cool, it saved me a fuel pump :))) Thanks a lot.
Thanks
Most switches will also have a small diagram on them to show what you need to know.
Excellent
Great job , thank you......way to go
Another great job with the video!
Thank you so much...🙏
and if it is a normally closed relay contact you blow your power supply... or at least the fuse in the ps if it has one.
Nice video ..what is wrong if the engine check light does not come on when ignition is on?
Tank you
Keeep rocking,,,
I have a 1996 dodge ram. And it starts most of the time, but there's sometimes that won't do anything. We got a switch adapted to it that would get it started. Any idea what it can be. Thanks.
Didn't get to see reading on the meter. All else was understandable, thank you. The meter reading was not in sight
Very helpfull god bless
Got this clicking starter overnight without earlier warning..new battery now..still same thing..naybe contacts to solenoid?
good lesson. i make car fuse and fuse tap .
Great video
Since it is for the starter would it be a solid state relay for high current draw ?
sir.. you should not ever use the Ohmmeter function on an energized circuit. it can 1.) Damage your DMM PCB circuits 2.) Provide inaccurate or irregular readings.
The multimeter checks for continuity by applying 3v to the circuit at a very low amperage, and checking for that 3v signal to return to the DMM through the COM port lead. Checking for continuity in a 12v circuit should always be done with the relay disconnected from all power sources.
If you want to do it energized, you use the DC Volts setting on the DMM and check for 12v to be present at all pins expected to be energized when the Relay coil is energized...
Dear sir I have a 1997 subarue legacy 2.2 my ques.is that my battery messup so I replace the battery I try to start it up and nothing turns no power at all inside the car but there's power in the battery could help me please I am to my last dollar.thankyou
Hi, I have a problem with my Honda CRV 2007, 4 cyl. When I started the car looks like my battery is low Volts or my starter is heavy to turn. I change the battery and starter but still doing the same, the motor start but on winter season is more slow to start and some times I run out the battery power. Thanks for you cooperation.
So if the relay is bad the vehicle won't start? Does a qx56 have a relay switch?
Thakyou
When I pulled my toyota corolla starter relay out, I saw something creamy sticked to the contacts of what seemed to be grease? Where that peanut butter could come from? Even the base of the relay has the same things and contacts are almost covered with that. Will I have to purchase the whole box where this relay and fuses live? Can I wash it down with alcohol? Is the sunny Florida also melting the electronic components of our cars, besides al the rest of the plastic components? My car with a 12.7V battery just gives me a "click" but it does not crank or start when I want but much later ...
When I turn on my car, I don't hear any clicking sound at all. Battery was tested fine. As I found online, I tapped on the starter gently with a wrench and then the car started fine. Does this mean starter has gone bad? Or is it starter relay? Appreciate the help.
Bad solenoid replace starter
Do you think 🤔 if doesn’t start at the first time is relay ?
Appreciate, understand it very well thanks you
So at the multitester is it using am which the red color cable insert?

Hi will a relay fault throw a warning light on the dash?
