71 GT-6: Battery (-) terminal is attached to an engine/trans bolt. Is there
any (should there be any) direct ground wires between engine and frame and body
and engine? It appears that any grounding is handled thru the vehicle wiring
harness. Advantages of adding direct ground leads between the major assys?
Others done this?
The reason that I ask is that my Crane XR-700 unit acted up on my way to work
last Friday morning after a brief (15 minute) hot soak (love those 24 hr. Home
Depot stores) on a decidedly cool morning. After 3.5 hours everything worked
OK again. In talking to Crane tech person, one of the suggestions was to check
all grounds. I have checked the ground path to the Crane unit and that is not
the problem but it did get me thinking about grounds and how modern cars with
all the electronics typically have redundant grounds between body and engine and
frame (if applicable).
