ELECTRICAL GROUND POINTS.
Many electrical problems are the result of poor ground connections. You can ensure that ground connections are
good by performing the following steps:
WARNING
Although battery disconnect switch must be on and battery ground cable
connected to test electrical circuit voltage, turn off battery disconnect switch or
disconnect battery ground cable before doing resistance tests or replacing parts.
This will prevent electrical shock and damage to parts and equipment.
(1)
Remove hardware connecting ground cable terminal lug to ground point.
WARNING
Cleaning compound, trichlorotrifluoroethane, for electrical parts is toxic and
flammable, and reacts violently with aluminum, titanium, barium, lithium,
samarium, sodium, and potassium. Always wear protective goggles and rubber
gloves, and use only in a well-ventilated area. DO NOT wear Jewelry while using
cleaning compound. Avoid contact with skin, eyes, and clothes, and DO NOT
breathe vapors. Cleaning compound fumes or vapors can take the place of air and
may become a cancer producing agent. DO NOT use near open flame or excessive
heat. The compound's boiling point Is 114°F (46C). If you become dizzy while
using cleaning compound, Immediately get fresh air and medical help. If
compound contacts eyes, Immediately wash your eyes with water and get medical
aid.
(2)
Clean mounting hardware, ground cable terminal lugs, and ground point with trichlorotrifluoroethane
(Item 40, Appendix B) and a scrub brush (Item 3, Appendix B).
(3)
Remove any rust with a wire brush (Item 4, Appendix B) and crocus cloth (Item 7, Appendix B).
