Rio Hondo Automotive Technology 106 Digital Presentation Project


hi my name is Kody Ballard and I’m a member of the Rio Hondo auto program this video is for my 106 electoral course in this video you’ll learn three things one I can locate a battery – how to remove a battery safely and three how to perform a simple voltage test to complete this video in a tutorial there are a couple things you’ll need first a pair of safety glasses safety first second it’s recommended that you have a good pair of sturdy work gloves three you’re gonna want a voltage tester last but not me a simple wrench set in order to deal with the bolts that you’ll be working with to begin we must first locate the battery the first step in locating the battery is to open the hood to open the hood we will have to enter enter the driver side door and locate the latch to release the hood most vehicles you’ll be working with when I’m looking to open the hood will have a latch such as this with a symbol like this with the hood open somewhere around the passenger or driver side door in this case the latch will be on the driver’s side or located underneath the steering wheel to release pull and there you go once the lever is pulled you will notice that upon returning to your hood when pulled up a releasing will form and you will notice that there is a trigger here we will need to lift up on that while simultaneously lifting up on the hood to open it and opening the hood and it’s important to identify the support beam that we use the hole up hood working in it with the hood open we can now see the internal components of the engine here you’ll see multiple components and into the engine let me throw the battery you will most will be in somewhat square to rectangular form and you’ll see two leads leading towards it this will be your battery to remove it it will typically be some form of retention bar secured by bolts addition to that there will typically be bolts reach holding on to your connections on a battery there are always two connections what’s typically called negative or more properly known as the ground and your positive which actually is properly named as your positive lead you’ll have to remove both the retention bars and the retaining bolts in order to remove this battery to begin removing the battery the first thing we’re going to do is use a wrench to remove these pieces depending on the make and model of your vehicle the size required to do this mayberry for this vehicle the size we need is a 10 millimeter wrench so to begin to remove it you want to twist if it’s tight and then begin turning to release the bolt with the retention bolts safely removed is downtime to remove or loosen the bolts holding the connections you with all the connections or intentions removed from the battery you mean now lift to remove the battery from its port there is however one case we you will not want to mess with touch or remove the battery and now it will be when dealing with high-voltage batteries to identify a high voltage battery there are a number of things you can do first is to locate the warning that clearly states high voltage I have a no-brainer but sometimes people don’t read the second thing is to look for these orange connections the reason for the orange is it’s the industry standard for high voltage connections what is high voltage it means that the circuit flowing through there is high enough to kill you if you or your car if you see or your car has a high voltage battery it’s advisable that you do not mess with it and take it to a properly certified dealership now back to our main video with the battery safely removed we can now voltage test it to identify the current state of the battery to do this we need a voltage tester to use a voltage tester you will want to have it set to DC and in the range that we will be dealing with most batteries use the automotive are 12 volts so the 20 volt range will be suffice you know there are two cables a black and a red the black cable is our ground lead and will be connect to the ground on the battery our red lead is the positive lead and will be connected to the positive lead of the battery to begin the voltage test you’ll want to turn your voltage meter on ensure that the voltage is reading zero with the voltmeter in place it’s now time to test the battery test the Barry the negative lead the black lead will connect to the ground of the battery the purpose of this will be placed here holed up in place since I only have one hand the next portion will be to attach the positive lead to the positive side of the battery again this is done simply because I lack a hands to hold one down after both connections are made is now time to read the voltage rating for automotive batteries the ideal voltage is twelve point six I’d you could tell from its reading of zero point eighty two eighty three ish this battery is why is known as discharged meaning this body does not have the power in it to turn on or run the vehicle it also means that this V battery is probably at the end of its life cycle it will have to be replaced and our dealership next I will show you example of what a better quality battery and the voltage rating on that on this other vehicle we are now test the voltage rating on this one this battery currently is in a running vehicle so hopefully the voltage will be a bit closer to what we’re looking for just as with last time the first thing we’re going to do is we’re going to connect the ground making contact and now repeat the step with the positive this time do you know something slightly different this time the voltage reading is reading at 12.45 43 considering that this vehicle is running we can tell from this reading the vehicle has the voltage to turn on it should be kept in mind however that a voltage rating of twelve point four such as the one on this is also a good indication that it’s almost time to change the battery on this one as well however unlike the other one this Barry has not become fully depleted now that we’ve tested the battery it’s down time to properly return the battery to the vehicle to do so carefully place the battery back onto the panel in which it was originally removed second step will be to carefully reattach the cable connections now that the cable connections have been safely attached down time to restore the retention bar with the retaining bar properly in place the battery has now been restored to the vehicle to finish off this tutorial we now simply have to close the hood and now be it thank you for watching the video and yeah that’s about it
