A vehicle’s battery serves a few vital functions. Most importantly, it gets the vehicle started. The days when an engine wouldn’t get going unless someone went to the front and hand-cranked it are long gone. As a result, a car or truck being totally dead is often an indication of battery trouble. If you hit the ignition and nothing happens, then your 7.3 Powerstroke battery should be the first suspect.+Read more
If lights appear on the dash, and you can hear something happening, then it could still be a battery problem. A starter needs a certain amount of power to turn the engine over, and those power requirements are higher in cold climates, or with large engines like a 7.3 Powerstroke. Batteries themselves should last several years, but things like overly high or low temperatures, or overcharging can drastically shorten that lifespan.
If the battery is dead, we have some good news. 7.3 Powerstroke batteries are easy to find and pretty simple to swap out yourself. But the battery may not be at fault. Corrosion on the 7.3 battery terminals can prevent a solid connection between the battery and the vehicle’s electrical system. Cleaning the 7.3 Powerstroke battery terminals may solve this issue, but if the corrosion is particularly bad a battery terminal replacement is likely to be the best option.
7.3 Powerstroke battery cables are another potential cause of battery trouble. The coating of cables, like many components, can degrade over time which could result in the cables shorting or corroding. There’s also a chance that rodents could get into your engine bay and damage the cables, again requiring a replacement. This could be a time to consider a 7.3 Powerstroke battery cable upgrade, as the price of a quality aftermarket component is negligible when you consider the overall cost of a replacement including labor.
