If your wrench is on the positive terminal and it accidentally touches anything metal, you will short circuit the battery. If you disconnect the negative cable first, and reconnect it last, then the car is not electrically connected to the negative battery terminal. While connecting or disconnecting the negative cable, you don't need to worry about the wrench touching metal parts of the car, because everything is at the same electrical potential.
Side-terminal batteries, common on General Motors products, require a small socket or wrench to remove the battery cables. The industry standard with automotive wiring is Black = Ground (which is negative), and Red = Hot (which is positive). This can be confusing when compared with wire used in buildings, where black (and other colors) are hot, and white is neutral, which has the same potential as ground. Dirt on the surface of a car battery can create a pathway for a tiny amount of electricity to flow between the terminals. To prevent the radio from losing its preset stations, I decided to try using this 12 volt portable power supply to keep power supplied to the car while the battery is removed. I connected the black alligator clip to the engine, and the red clip to the positive battery cable.
The arms (arrow) go underneath the cable end clamp, and the center pushes against the terminal post on the battery. Under the cap there is (or was) a round brush to clean the inside surface of the cable end clamp.
My first car had no battery hold-down clamp or strap, and since I drove like a freakin' yahoo the battery slid off its tray and rested against the alternator.
I sprayed some diluted Simple Green on the battery and used a small nylon brush to scrub the dirt and oily residue. I wondered if silicone dielectric terminal grease was meant for battery terminals, so I read the package that I had in my supply of automotive chemicals. I applied some dielectric grease to the battery terminals and spread it around with my finger.
I also applied a thin film of dielectric grease to the inside surface of the battery cable ends.
The good news: By connecting the portable power supply to the positve cable (and grounding the black clamp to the engine) I did not need to re-program the stations on my car radio.
A clean battery with clean connections will provide the greatest possible cranking power on cold winter mornings. I think it's a good idea to do this battery maintenace once a year, preferably before cold weather sets in.
Many years ago, when I was 19 and knew nothing about fixing cars, I reasoned that a recent invention called silicone caulking might work to patch a small hole or crack in the plastic case of a car battery.
If power supply from battery to your car is affected, it is most likely that the battery’s cables have developed corrosive material around them. You will need a wrench to loosen clamps or connectors connecting the cables to the battery's coil. After removal of negative cable, trace it to its anchor position, which most likely will be on top of engine. Hey Pretty Handy Girl readers, I’m stepping up to the podium today to prove to you that I can do more than just wrap presents around here.
There comes a time in every car owner’s life when you get stuck and your car is difficult to start. You can purchase a new car battery at your local auto parts store or discount stores like Costco.


Ok, seriously she made me write that last part.A  Pop the hood of your car and prop it open.
The battery should no longer be connected to the car at this point.A Look closely, does your car battery have a protective cover surrounding it? At this point, you will want to use the wire brush to clean off any corrosion from the battery terminal clamps.
Gently set the new battery into the car.A A  You can spray a little anti-corrosion spray on the battery posts if you like. Re-attach the mounting bracket by hooking the rod back onto the stand and then attach the bolt to the front. Did Brittany ever tell you about the time that I changed the oil on my car when we were dating?
This article explains how to resolve a System Fan (90B) error from appearing when you start up your HP Pavilion G6 Laptop. In this example I have used a HP Pavilion G6 but this article is also applicable to many other laptop models as well as the CQ series from HP Compaq.
I found that I did not need to remove the heak sink\fan – I could pull the fluff out from between the blades.
Also, my laptop is g7 pavilion, which luckily is almost exactly the same (component-wise) as the g6 so your instructions were 98% correct for the newer model. Repair shop quoted me $150 for labor alone and thanks to you all I had to buy was a $5 tube of thermal paste.
Hi, I was having my screen replaced and he said that the computer started throwing a 90b error and needed a fan. Place the open end of the pipe on a vacuum cleaner flat against the fan vent in the laptop casing. The voltage isn't harmful, but the sudden unexpected sparks will startle the $hit out of you, and could even burn you.
After that you can disconnect the positive battery terminal with minimal risk, because if your wrench touches any metal parts of the car there is no complete circuit, and nothing happens. There were two very long bolts (red arrow) that secured the bracket to the body of the truck. The alternator pully carved a nice little groove in the side of the battery case, allowing half the battery acid to leak out of one cell. This will make it easier to read when I'm jump-starting someone's car on a cold dark winter night. Then I went to my local garage and paid a whole dollar for them to top-up the acid in the leaking cell.
This includes clamp, and you will either need to clean the connectors or change the cables. Carefully, loosen the clamps, it is likely that they have been eaten up by the corrosive material completely.
Also, it is possible that connector on the anchor side of the cable is also corroded and will need cleaning with a wire brush before removal.
But, when your wife is waving a camera in your face and telling you to stop and hold that pose, it can take considerably longer.
You might need to put the adjustable wrench on one side to secure the nut head while turning with the socket wrench on the opposite side.
One day it’s about home decor, building something, planting something, car repair etc. The reason I ask is because your layout seems different then most blogs and I’m looking for something completely unique.


The g7 has a couple less screws in some places, but otherwise it is constructed almost identical to g6. A huge money-saver and fixing my own pc hardware problem was a fascinating (and frustrating!) experience. He changed the fan and I can clearing hear the fan running but I still get the 90b error message? I’d already had my laptop apart once and was about to order a new fan when I read this and was able to fix it as you described. There is so much current (amperage) available that your wrench literally becomes an arc welder. Corrosion can increase the resistance of the electrical connection, which can prevent the battery from charging properly.
But I've been doing this for years and my car batteries usually last 5 or 6 years before they need to be replaced.
See the cables and connectors on the battery coils, if they have too much corrosive material around them, clean it with a wire brush so that you can see the collectors and cables clearly. An old battery frequently emits gas and corrosive material, which is explosive and can cause a risk of injury if the negative cable of the battery is not removed before the positive cable. Then trace the positive cable connection down on the anchor and clean it before removing it from that end. Brittany’s car battery had been showing signs of weakness, but it was hanging in there.
Cool showing off my mad shade tree mechanic skills I started up the car and asked her to look for any leaks.
I managed to do this without taking the heatsink off, which some people might find easier, I just undid the one small fan cover screw visible without taking the heat sink off and was able to the lift the fan cover enough to pull the fluff out with tweezers. Corroded battery connectors can create so much voltage drop that the car's starter motor cranks slowly or not at all. Instead, follow a step-by-step approach, from cleaning the connectors or clamps to actual removal of the cables, to avoid raising any safety concern for yourself and the vehicle. If you leave the battery open, the level of corrosive material will be excessive and will need detailed cleaning.
When she took it to the dealer for a recall issue, the mechanic wanted to charge her $$$ to change the battery. Rarely are any new parts required for this fix but you will need thermal compound paste as you have to remove the heat sink from the processor. Being the frugal Handy Guy around here, I told them to forget it because she could do it herself.A  Somehow she convinced me to do it (must have been my extensive auto parts store work experience from high school). I assumed I did not install it correctly or missed some connection but could not see a missed step. I tested the fans with a 9V battery and both worked so I assume the fans are actually fine. I tested voltage at the fan plug on the mobo and did not get anything like 5V, which is what the fan shows.
I tested the power adapter and it shows 19 volts, as does a second adapter I had so I am ruling out that part.
