NOTE: Harnesses should be installed and connected for this check, internal chassis
wiring through the connector to ground is permissible for this grounding.
Battery Ground Point .010
Static wick mounting plates (TCO Model B-4) P/N 452-094 1.00
NOTE
: Where jumper wires or cables are used to accomplish a proper bond, resistance between
the jumper terminal and the component or structure shall not exceed .001 ohms. The
controlling points for measuring resistance will be within the limits of the cleaned area to be
bonded and within 1/4 inch of the exterior limits of the bonding jumper terminal or material
called for in the bill of materials of the drawing.
Resistance to ground will be measured from wire terminal to structure for electrical /
electronic equipment not internally grounded and from mounting flange to structure for
equipment that is internally grounded.
