Oxidation, can still bring a truck to its knees, even a large prime mover. Points you should note for your truck’s well being.
- Don’t ever use a test light with a piercing probe. Those poke holes in the wire that open up a gateway for moisture. Once wire is wet, corrosion sets in immediately.
- Don’t use non-sealed butt connectors. These are fast and simple, but offer no protection from corrosion. Use soldered and/or crimped connections with double-walled heat-shrink tubing to seal and insulate the connection.
- Learn how to repair electrical connectors properly. There are procedures for repairing various sealed connectors supplied by the manufacturers. Follow them. If there’s dielectric grease or some other insulator inside a connector, make sure you refill the repaired connector.
