3 Easy Tricks To Start a Dead Car - Without Jumper Cables

hey do-it-yourselfers today I'm going to share with you three of my superpowers that should allow you to start a vehicle that has a dead battery and/or a dead starter or a vehicle that has problems with this ignition switch today I'm going to share with you not only the how but the why as well but make sure you use these powers for good not evil alright and actually before we start and our superpowers I have a huge favor to ask and that is to both my current subscribers and for my subscribers that are going to be subscribing after watching this video and that is to make sure you click on the Bell notification or the bell icon that's right next to the subscribe button because unless you click on that you are not going to be notified of my new videos that are going to be coming out alright so in the first scenario let's say you get in your car put the key in the ignition you turn the key and nothing alright so if that's the case you need to figure out whether there's a problem with your battery or maybe it's your starter so what do you can do to narrow your problem down is to let's say your car has automatic windows make sure you can use them and the window goes up and down as fast as it normally does you can also turn on your headlights and make sure they're nice and bright now this might be hard to tell during the day but at night it should be pretty obvious now if they're not nice and bright then obviously there's a problem with your battery but they're come on nice and bright you still need to do another test which is to obviously try to start your car and then observe your headlights when you turn your key to the start position your headlights should dim you know this is obviously again gonna be easier at night but if you're doing it during the day have someone else stand outside the car and look at your headlights when they dim that they indicate that power is actually being routed through the starter and your starter is not the problem and indeed is the battery that's too weak I'm going to get in there and start this car and this car doesn't have a bad battery nor a bad starter but you will still be able to see the headlight stem for a split second all right so let's say your headlights don't dim when you turn the key to the start position at the same time you do not suspect you have a weak battery because your windows work properly and your headlights are nice and bright well the next likely culprit is probably your starter especially if your starter has been acting up lately all right so the first thing you need to do is to find your starter now if you watch my previous video you would remember that the starter is the component that draws the most amount of amps on your car now the starter is grounded through the engine which is grounded through cables that are connected to the chassis and the chesty obviously is grounded back to the negative side of your battery however it does need to be supplied by a wire or a cable from the positive side of your battery so basically you start at the positive side of the battery and follow the cables that come from this side back one of them one of the thick cables should go to your starter now on this car you can see one cable get split off and go to this junction box and the rest of them go underneath this junction box and then they come out from this end and if you follow them they go towards the underneath the intake manifold and right there you guys may not be able to see this but right there is our story motor which is right now sitting there like this now a lot of times when your starter motor stops working it's a problem with the brushes wearing out or developing corrosion and not making contact with the commutator so here's your brushes right here now this one there's four of them and here's where they need to make good contact all right so here's even a closer look and if you look closely you can already see these brushes being kind of worn out but anyway when they don't make contact with this end the commutator the the they're not current doesn't flow through this starter and it doesn't spin now what you can do is to grab a long screwdriver pry bar piece of wood whatever you can get your hands on and try to get on the starter motor and then give it a good couple of taps with a hammer and while you at it try to tap on the solenoid as well and what that does is to hopefully allow the brushes to make good contact with the commutator or move them just enough so that they're making better contact than they were before and hopefully allow you to start your car and the same technique might work with a dead fuel pump as I've demonstrated in the past the hell out of our fuel tank and maybe a fuel pump will start alright next up let's talk about a circumstance where you suspect problems with your ignition switch and when we're talking about ignition switches we're not talking about this and this is your ignition locks on there where the key goes in the ignition switch is an electrical component that goes at the back of your ignition locks on there and switch assembly what it does is basically routes power from your battery to the different control modules on your car so for example when you put together the car turn the key to the on position it routes more power through the ignition switch to your ECU your body control module module your car's computer basically and that's when you get the lights to come on in your dash now science you might be having problems with your ignition switch is that when you put the key and turn it to the on position the lights don't come on on your dash and you have to you might have to like push the key you know wiggle it play with it and then the lights come on and off then that could mean a problem with your ignition switch all right so in this scenario let's say you turn the key to the on position sometimes the lights come on sometimes they don't but let's say this time they come on but when you turn the key to the start position the car doesn't start alright so if that's the case that means a signal or a power is not being sent through your starter solenoid to the signal post of your starter now what you can do is go to the junction box and locate your starter relay now we're lucky to have this info at hand and our starter relay is this relay right here and then you locate pins 30 and 87 on this 4 pin really sometimes you have a 5 pin oh really but regardless you need to look at pins 30 and 87 in our case it's gonna be this pin and this pin and then you find the corresponding terminals on the junction box which are going to be nice too and then you jump those two terminals now however before you do this make sure that you're doing this correctly because if you jump the two wrong terminals you can damage the wiring inside your car and then if you damage the wiring that goes through the junction box then diagnosing and fixing that is gonna be a lengthy process even for a competent and so make sure you really know what you're doing now sometimes if you're lucky enough on your really you can see a diagram that will tell you which side is the switch side and which side is the load side you're not always this lucky and you should really learn about relays before you attempt this so you don't damage your car now if you're interested in learning these I have a video on how you can test relays you'll learn all about relays if you watch that video just have to do a search and on my channel for how to properly test relays and it will come up alright so we'll do this live so people don't think we're cheating so we put the key in the on position make sure the lights come on [Music] [Music] there we go now you might be saying hey when I put the key in the ignition nothing comes on no lights come on at all if that's the case then things could be a little bit more complicated you need to get to your ignition switch look at a wiring diagram and see which wires take power to the different control modules on your car supply power to those wires and then you should be able to start your car from your ignition switch at the same time bypassing your ignition switch all right up next we're gonna talk about bump starting or push starting your car that has a bad battery and or a bad starter now unfortunately this only works on cars that come with a manual transmission and the way this basically works is that we're going to use the transmission in this car to turn the engine now basically the way it normally works is that power goes from your engine to the transmission then from the output shaft of the transmission to the wheels and then they turn the wheels and your car gets going now but by doing this we might work do it backwards or work our way backwards we're gonna use the wheels to turn that the output shaft of the transmission in turn is gonna turn the gears inside the transmission which in turn are going to turn the engine so yeah when you use the transmission to turn the engine over as the engine turns over it sucks in the air compresses the air fuel mixture and then your course computer gets that crank signal and starts the spark plugs and then your cars gets going also when you turn the engine your alternator turns creating a bit of current which is usually enough to get the cars computer going where you can start the whole ignition timing also this car is a perfect example for this because indeed it does have a weak battery by the way that's a telltale sign of a weak battery all right so the way this works is you get in your car get the keys put the key in the ignition and turn it to the on position now your lights may not come on but this car just has enough juice for the lights to come on but next you push down on the clutch and while holding the clutch down you put the car or the transmission in second gear all right so next you need to get someone to either push your car or sense as you can see I'm parked downhill I'm simply going to release my emergency parking brakes and then once the car starts rolling and builds up some momentum I'm gonna release the clutch quickly and you will not hear a noise as normal with a starter so here we go you'll just get a bit of a jolt and your car gets going as you can see and here so yeah make sure you use these super powers for good not evil now if you enjoyed this video I want to support my channel all you have to do is watch another one of my videos you can either click on this one in this corner click on the one below it
