SECTION 1 - Engine Compartment
Battery Ground Connection
The battery ground cable runs from the negative side of the battery to the rear bolt of the intake
manifold on the driver's side of the engine block. At least, this seems to be the most common
setup. Shown in the photo above right, I added an additional ground cable which runs from the
intake manifold bolt down to the starter which supposedly helped the car to start better.
In our survey, the battery ground was connected to various locations including the rear bolt of the
oil filter, and various other bolts on the intake manifold. I guess anywhere is fine as long as it
makes a good connection. I don’t know if Studebaker had a particular location identified.
The parts book lists this cable as 22". The original battery positive and negative cables specified
by Studebaker Engineering beginning with the then new 12V. Negative ground system used on
all 1956 models required the letter "N" to appear on the battery post end of the negative cable.
Likewise a letter "P" appeared on the positive battery cable.
