Ground Bonding

If a vehicle is not properly bonded to ground, static charges can increase. This increase can cause
noise from electrical arcing. This type of noise is suppressed by bonding the part using one-inch wide
ground straps (keep them as short as possible). Some common points where bonding may be helpful
are listed below (see Figure 10-5).
A. From engine block to the firewall.
B. From engine block to vehicle frame at points where the engine is shock-mounted.
C. From the battery ground terminal to the vehicle body.
D. From top of front wheel "A" frames to chassis, particularly in cases where rubber-mounted
members are used.
