How-To’s: Checking Cables and Connections

Step-by-Step Checking Cables and Connections

From starting systems to electrical systems, a good connection between your DieHard battery and battery cables is essential to good vehicle performance. Maintaining that connection can be as quick and painless as a peek under the hood.

With these simple steps, not only can you examine your cables and connections but you can replace the battery cables if necessary and have your vehicle up and running in no time.

  1. With the engine off, check both of the battery cables for cracks, burns or corrosive deposits and assess the damage. If there are breaks in the cable insulation or corrosion eating away at the wire, it's time to replace both cables to avoid short-circuiting onboard computers.
  2. Starting with the negative side of your DieHard Platinum automotive battery, disconnect the cable from the battery post by loosening the nut with a pliers and removing the cable. Track the negative cable from your hand to where it ends on the engine block and disconnect it, removing it entirely from the vehicle.
  3. Detach the positive cable from the DieHard Platinum automotive battery terminal post and trace its opposite end to the solenoid or starter relay and unbolt it completely.
  4. With new battery cables of the same size, gauge and terminal, begin with the positive cable and reconnect it to the solenoid. Check the posts and connectors on the battery to make sure they're clean, ensuring a good connection, before reattaching its opposite end to the positive terminal post and tightening the nut or bolt.
  5. Attach the negative cable back to the side of the engine block and hook up the terminal to the DieHard Platinum automotive battery's negative post, making certain the connection is clean and secure.
  6. Spread a thin layer of lithium grease or petroleum jelly on all exposed metal to slow the buildup of corrosive deposits. Start your engine.
