Many electrical faults are caused by bad ground points.
To ensure a good bond for ground points on any metal surface in the car, proceed as follows:
1) Clean the area around the bolt hole down to bright, shiny metal. An easy of doing this is to use a pilot bonding end brush in a drill to clean around the hole (see below for where to get these brushes). If a brush is not available, scrape all paint off of the metal around the hole and then use sandpaper to get a perfectly clean surface.
2) Once the surface is cleaned down to bright, shiny metal, coat the surface well with any conductive, anti-corrosion surface compound, such as Kopr-Shield (see below for where to get Kopr-Shield).
Pilot bonding end brushes are available from MSC Industrial Supply Co. (800-645-7270)
