Once again, the ugly battery connections are present on another truck. This is a M1008 that I purchased 4 years ago.
While changing the radiator (another disaster story) I noticed that the battery terminals were attached with the hammer method of crimping. Not being a fan of a ball peen crimper, I decided to clean up the connections and attach new lugs properly. Replaced the post terminal connectors and covers as well.
Fortunately for me, my occupation has the correct tools and materials to complete battery connections properly. Many of our customers have battery back up systems that require proper installation and maintenance.
One of the wires looks like it had water in it and showed corrosion (black) on the copper. So I replaced the entire piece of wire.
Cleaned up the bus bar and both sides of the terminals as well. Don't forget to clean the underside of your nuts before putting them back on the bus bar.
Cleaned up the battery posts as well.
Another reminder, it's the connections that you don't normally see that are the most important with high current connections. Simply looking at them is not a way to determine if they are good. Take the time to take apart your connections and inspect them for any defects. Minor amounts of corrosion with only get worse with time.
Remember to always practice safe working procedures when working with any batteries. Eye protection, covering of exposed terminals, insulated tools (if possible) and proper sequence of disconnecting and reconnecting. They are very unforgiving and will hurt you when you don't treat them with proper procedures.
