What is the best method for cleaning all of the electrical contacts??
The solderless terminals could use some cleaning as well as all of the fuse contact posts. |

I used a radiop Shak product that is an electrical terminal cleaner. A q-tip and toothpick helped also

Worked at a computer company (in a past life) and asked this materials engineer (whose specialty was connectors) what to use. He recommended contact cleaner. In extreme cases (green connectors) he said a little rubbing with an eraser might work. (Followed by more contact cleaner)
He also recommended dipping the connectors in baby oil after treatment to keep oxygen from them. In a pinch, I have been known to use brake cleaner instead of contact cleaner and toothpaste for a mild abrasive. The absolute best fix was swapping out that ugly wiring harness for the pristine one from the parts car. I sure don't want to do that again.

Diapers? If you look around electronics stores, you may find a small tub of dielectric grease, apply it to both sides of closing connectors after you clean them with Blue Shower, or sameish, and use a small brass brush (fuzzy one works best) on hard to clean ones. (brass is softer than steel... yaya) A bore brush works great, they make tiny ones, good for the deep connectors. (not a steel brush) The grease will save you from going back in there ever again, use sparingly.. Dab'l dooya, Mate! M |

Thanks,
at the same time, I'm going to re-do the harness to eliminate the "seat belt warning system relay with integrated buzzer" (J34) as well as do a few things with the main relay board for my Megasquirt installation. |

Mike, I have found that to properly disperse the green growth on the terminals (we call it "fretting" here at Cadillac) we use electrical terminal spray cleaner from your local electronics store & GM terminal coating part # 12377900 available at any GM parts location.
