Description / Abstract:
This test procedure is intended to evaluate and/or validate
electrical ground schemes for use on the body or chassis. There are
two classes based on the expected environmental conditions. Exposed
Grounds can be located anywhere in the vehicle (except on the
powertrain) and is the class for which most schemes should be
tested. Unexposed Grounds can only be used in the passenger
compartment or trunk and as such are special cases.
This procedure as written is not intended for testing powertrain
grounds where high temperatures and vibration levels may be
encountered. These situations may require modifications to this
procedure and are left to the Responsible Engineer to
determine.
This specification does not specifically address validation of
terminal to wire electrical crimps. Crimps are tested to
SAE/USCAR-21
