If your truck won’t start, or the vehicle’s electrical system is behaving oddly, then the 7.3 Powerstroke battery is one of the first places you may look. However, that’s not always the problem.

This can lead to a situation where the cables can’t form good contact with the 7.3 Powerstroke battery terminals, or the cables are shorting out somewhere. There’s also a chance animals could have climbed into your vehicle and caused damage to your cables.
Luckily, this can all be fixed. At worst you will have to replace your battery cables, which isn’t too big a job if that is the only problem with your truck’s electrical system. You can even opt for a 7.3 Powerstroke battery cable upgrade, which can improve reliability and allow for more consistent voltage.
If your battery terminals are corroded, and you don’t want to splash out on a completely new battery for 7.3 Powerstroke, then consider a 7.3 Powerstroke battery terminal replacement instead. If your cables seem fine, and a test shows the battery is dead, then you’ll be pleased to know that 7.3 Powerstroke batteries aren’t hard to find and a battery replacement is something you can do yourself. Just be aware that you may need something a little heavy duty to turn that big 7.3-liter engine over. Some vehicles with the 7.3 Powerstroke have two batteries wired in parallel, so make sure you read your truck’s manual and check out the engine bay before making an order.
