How To Test and Replace A Starter Relay

Автокөліктер мен көлік құралдары

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.

    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!!

    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.

    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.

    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

    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.

    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 ...

    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.
