    It's now the 2nd time that I reviewed this educational video on the electrical components of a motor vehicle starter system. I think that it's the best one I have viewed & will help me resolve my starter problem. Thank you from Johannesburg, South Africa.

    A good teacher is the one that knows how to make others to learn and understand the easiest way.
    You're an excellent teacher, I wish I'd had people like you around me. Most of the things I had learned is on my own with God's help figuring out how things work. Not everybody has the talent and paciente to teach others, and not everybody likes to teach others what they know that gives you a plus.
    Thanks for sharing your knowledge and may God give you more. God bless you!!!

    Thank you for incorporating the fly wheel gear. That explains a ton about how a car actually runs. Your entire presentation is very well done, extremely detailed and thoughtful. I only stopped to watch your video to see if i was connecting my starter correctly or not and got educated in so much more, so thank you. Subscribed. I hope you have more videos similiar to this. What about the generator/alternator in this wiring set up? I dont think i see one or did i miss something? My car had an inline fusible link from the starter to the alternator that burned out apparently but i was unable to reach it to replace it so i simply have a power/positive cable from the starter to the battery and i also have a power/positive cable going to the battery instead..... Is this a bad idea?

    • @diypotentials
      @diypotentials  Год назад

      Thanks for the kind words and for subscribing. The generator/ alternator wring set up might be a good topic for a video project in the near future. Regarding the blown fusible link, the new circuit might work without it, but it doesn’t offer the protection from current overload. I’m not familiar with your vehicle, but the fusible link was placed there for a good reason-to prevent costly damages to components. I hope you were able to replace it. Thanks again.

    I see this video is made for electric engineers as they understand this stuff, but I have made it out understanding almost all the ideas based on my school physics!
    Just one thing I didnt get: what is the main purpose of the small relay that is connected to both the safety switch (park/drive) and the contact key? You said it is for safety, but how?

    • @bernardocisneros4402

      Any answer for the question?

    • @bernardocisneros4402
      @bernardocisneros4402 2 месяца назад +1

      @@ahmedtzaki4476 The purpose of the starter relay in this video and the vast majority of relays is to save money on wire and switching devices. A relay uses a low current circuit to control a higher current circuit. The use of relays is not due to safety reasons. It's mostly due to economic reasons. The "neutral safety switch" is used for safety so you can only start the car in park or neutral and not in drive or reverse. If you didn't use relays, you would have to use bigger and more expensive ignition switches that can handle higher currents. You also would have to use a larger quantity of thicker wire to handle the higher currents. Using the relay you can use thin wire from ignition switch to relay control circuit pin #86 and thin wire from relay control circuit #85 to ground. Using the relay also allows you to use a smaller less expensive switch. Using the relay, the only places you have to use thicker and more expensive wire is from battery positive to relay pin #30 and from relay pin #87 to starter solenoid.

    Nice video! I have a quick question. I replaced my starter on my 94 bmw 325i thinking that I have a bad starter. I checked the battery is good, starter is good, relay is good… but sometimes it won’t start. I bypass my ignition switch and used a push start. Everything works fine but sometimes it won’t start. I read online that it maybe the wire coming from my relay to the starter is bad or corroded… can I just simply put a 12 volts to the starter solenoid so when I push start the car it will start? Thanks in advance

    • @diypotentials
      @diypotentials  Год назад

      HeyJay, I don’t recommend doing that because solenoid is already connected to a 12volts. It might be that the ground wires are loosened or rusted…That would be something I would check next …Thanks!

    Question, I understand that accessories will be on when the key is in ignition position but is there a way to only turn an accessory on only after the starter is on? So basically, on ignition position it won't turn on until only after the starter cranks the engine on.

  • @DJdavefromlondon
    @DJdavefromlondon 10 часов назад

    Surely the small relay 30 connector should be connected directly to the battery positive and not the ignition switch. In other words ,when the ignition switch is turned to start the car, the small relay gets low amp power through 85 and 86 to energize the coil which pulls 87 towards 30 to make a connection. The reason for this relay is that higher amps passes through 87 and 30 because the bigger solenoid needs/ pulls higher amps. You do not want these higher amps going through the starter switch. The entire purpose of the relay is to not put high amps through the starter switch.
    Then the bigger solenoid does the same thing , it takes the higher amps to energize the bigger coil that then allows even higher amps to flow from battery to starter motor.
    Let me know if I'm wrong

    Hi, great video. I have an MOT (Ministory of Transport) test due on 2 old vehicles, but one has an Ignition problem (randomly won't start and won't affect the outcome of the MOT )and isn't being used, I have renewed the IG switch on advice, but it wasn't that. So to use it, if the other fails the MOT test, to keep us mobile (we are remote living) If I feed (from the + batt term)the large red wire on the solonoid will this bypass the IG switch and turn the motor over and start the car (ignition switch in the on posistion too) The garage said it was the large terminal ,but I thought it was the "S" terminal the one you point to,(and he changed his mind ),, ,does it matter ? Thanks for reading. Chris (UK)

    • @diypotentials
      @diypotentials  10 месяцев назад +1

      If I understand your question correctly, the answer is, no. I don’t recommend doing that because the solenoid is not designed to take on so much current. That is why even the signal wire has a fuse. In addition, connecting the positive wire to the solenoid will not provide electricity to the starter motor because each runs on different circuit. With possible 400 Amps or more running through the solenoid tiny coil windings, the possibility of it being destroyed it very likely. But it is your car, not mine. Thanks for reaching out. Happy new year!

    • @edinfific2576
      @edinfific2576 10 месяцев назад

      To answer your question: yes, you can start your engine by connecting the solenoid straight to the + terminal of your battery.
      Just make sure you only keep the contact on until the engine starts, typically about 2-3 seconds!
      The starter solenoid will not burn out because it has enough resistance to the 12 volts from the battery. It was meant to run on 12 volts.
      I was actually stuck on the road few days ago, on January 1st, it was night, holidays, and away from any repair shops.
      The mechanism between my key and the ignition switch under my wheel broke, but at least my steering wheel was in the unlocked position.
      After calling a car mechanic/electrician, I was advised I could start the engine by pushing the car since the contact was on (and I couldn't turn it off with my key).
      Since pushing was out of the question, I figured that I could bypass my ignition switch and go straight to the starter solenoid from the battery's positive terminal.
      I was aware that the starter was connected to the chassis on the negative end, and with a large wire on the positive end, i.e. always connected to the battery, and that it is engaged with a solenoid which requires a few amps (5-10 amps), while the starter motor uses at least 100 to 200 amps.
      I checked the internet for the starter motor location on my car, got my jumper cable, laid under the front of my car, took the solenoid connector off and attached the jumper cable.
      As soon as I touched battery's positive terminal, it started cranking and the engine was running within 2-3 seconds. I was very happy because that saved me a lot of money and time compared to towing my car and finding transportation for myself (at least 2 hours away from home).
      When I arrived home, I had to stop the engine by shifting to 4th gear (by force), since I couldn't disengage contact, and disconnecting the battery would still leave the generator running which would both keep the engine running AND likely burn car's electronics due to large voltage peaks without the battery loading and smoothing the generator's output voltage like a capacitor.

    • @diypotentials
      @diypotentials  10 месяцев назад

      Wow. Amazing story. Glad you made back home okay. The key point here is that you are able to disconnect after 2-3 seconds just enough to get it started. Nevertheless, it is great to know. Thanks for sharing.

    So I have a 2003 Ford Ranger with a 3 l. It runs great it's a great truck on the original owner what about three or four years ago it started with a no crank no start issue and I'm taking it in and they said that they don't know what it is I've changed the starter the battery and the ignition switch and it still does it does it!! I can hear the relay clicking can I switched it with the blower relay and it still does it!? I think the only thing left is to look underneath the fuse box for corrosion in the starter relay connections?

    • @Andyfunsail
      @Andyfunsail 9 месяцев назад +2

      Try connect the terminals on the solenoid. That will get the starter motor turning and the engine should start. Sometimes the solenoid gets sticky. So if you head the motor turning but not starting it could be sticky. Give the solenoid a gentle tap and try connect the terminals on the solenoid again. Hopefully the engine will start. You can use a screw driver or I've got a short piece of thick insulated cable I use to connect the terminals.
      This should give you an idea of it's just the solenoid that's giving issues. I'm not too good at testing the rest of the system.
      Good luck!

      If you don't know exactly what your doing, I wouldn't do that. Most starting systems on today's cars are not as simple as his demonstration. They involve a lot more electronics. On most cars you can ruin an engine control module if you mistakenly jump the control side with battery positive to slot 85 and slot 85 is the ground side of the control circuit controlled by the ECM.

    DONT UNDERSTAND the three wires going into ignition switch ? power into ignition goes on B as in from battery. S on ignition switch goes to 30 on relay . But which terminal on ignition does wire from 86 on relay go ? You keep saying ignition but which terminal ? If the ignition has B battery S start solenoid G ground and A/L acessories / lights then is it the A/L or the G ? I am guessing A/L because G ground does not seem right to me .
