Wired! (Battery Cable Service)

Colder weather brings out the worst in a vehicle's battery.  On a very cold day, you may have experienced that your engine cranks slowly when starting.  But while it may be the battery itself, it may also be the parts that transfer the power to other the other electrical components, the battery cables.  After all, you have to have some way to get the current out of the battery and out to where it needs to go.

Battery cables have a couple of enemies: corrosion and age.  You may have looked under the hood and noticed a light-colored powder or crust around the terminals.  That's what happens when acids corrode the ends of the battery terminals.  Corrosion inhibits the connection and may reduce the amount of power getting to the electrical accessories to the point where they are not working correctly, if at all.

Here are some symptoms of problems with your battery cables. You might notice a clicking sound when you turn the key, some of your vehicle's electrical parts (like the sound system or the horn) don't work or, in some cases, the vehicle won't start at all.

When you take your vehicle to a repair facility, the technician will use instruments to check voltages to see how much current is getting to what location. That includes a starter draw test during which the battery's voltage is checked when the starter is cranked.  The technician will also visually inspect the cables and the charging system. To make sure the alternator is putting out the right voltage, the technician will measure that as well. 

If the problem is found to be the battery cable assembly, the entire set may have to be replaced. Sometimes they can be repaired. 

During the colder months, it's vital that your vehicle has the proper power going to its electrical components.  Having a vehicle that won't start or run smoothly is not something you want to battle with when you're already up against challenging weather.  Keep your electrons flowing… and your vehicle moving.

Wash Me, Wash Me Right (How to Wash a Vehicle)

Most would agree they'd rather drive around in a clean, shiny vehicle than one coated with a layer of dirt.  When warmer weather comes around, some of us are bound and determined to wash our own vehicles.  And to protect the paint and its luster, there are a few things to keep in mind when you get out the bucket and soap.

• Cool body.  It's not a good idea to wash a vehicle when the body is hot.  If it's been sitting out in the sun or you've been riding around on a sunny day, make sure you cool your vehicle off by either moving it to the shade or wetting it down with cool water. The problem with washing a hot vehicle is that it's going to dry so fast, minerals in the water can form hard-to-remove spots on the paint.  And some of those can be really difficult to get out.  Best to avoid it.
• Slippery when wet.  Make sure you wet your vehicle down thoroughly before you get the washing mitt out.  Experts keep a couple of buckets of soapy water on hand, and they use soap especially engineered to remove dirt from a vehicle without stripping off the wax that might be on it. 
• The washing mitt.  Experts say to use a mitt with hundreds of moisture-absorbing strands on it.  Start washing at the top and move down.  If you keep dipping the mitt in the buckets frequently, a minimal amount of dirt will stick to it and that will prevent scratching the paint. 
• Wheels last.  Wait until you've finished washing the body before washing the wheels.  Some detailers prefer special wheel-washing tools or brushes. 
• Rinse it well.  Hose the vehicle off thoroughly to get all the soap off, then dry immediately.  Some people swear by a chamois, others like cloth better.  Cotton or microfiber towels will do.  

The next time you have your vehicle in for maintenance, you might ask your service advisor for recommendations on vehicle washing accessories.  They are usually up on the brands that produce the best results.  You may not be a detailing pro, but there's no reason your vehicle can't look like you are.

The Need for Speed (Wheel Speed Sensor Maintenance)

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days.  Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before.  When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue.

Often the problem when the ABS light comes on is a faulty wheel speed sensor.  (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up. 

If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system.  You'll still have working brakes, but you will lose the functionality of that computerized system.

When your vehicle warns you the ABS has a non-working sensor, you can have a technician check to see what's going on. It could be one of the sensors is dirty and a cleaning will solve the problem.  But it also could be that one or more sensors needs to be replaced. 

A technician will use computerized diagnostic equipment to determine what and where the problem is, replace any bad parts and then check to make sure the system is fully operational. 

Antilock brakes and traction control are significant technologies that help prevent your vehicle from slipping on less-than-perfect road surfaces, especially useful during wintery weather.  Make sure they're helping you drive the way they designed to.
