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.

When you start up your gasoline engine car, you may not know that it’s using the same ignition principles as it has for decades.  You have spark plugs that require enough power so a spark can jump across a gap at its tip.  Years ago, a vehicle’s 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing.

The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off.  That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical “points” had to be replaced and adjusted every 12,000 miles/20,000 kilometers.  Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers.

The next evolution came in the 80’s when the distributor was replaced with a couple of sensors which talked to a computer.  This “DIS” (distributor-less automotive ignition system) was a big advance.  Plus, it didn’t use just one ignition coil for all the cylinders.  It had coil “packs” that each provided spark to two cylinders.  That way, the voltage could be boosted even higher, to 30,000 volts, which helped engines be able to ignite a leaner fuel/air mixture.

Recently have come even more improvements.  Now instead of coil packs, there’s a coil that’s attached to each spark plug.  No more spark plug wires means less maintenance. Plus, a stronger, hotter spark of 50,000 volts can make an engine more reliable, increase fuel economy and reduce emissions.

No matter what ignition system your vehicle uses, your vehicle service facility has a staff of technicians trained to work on the latest technology.  Make sure to have your vehicle maintained regularly so you can take full advantage of these modern engineering marvels.
