Jimmy,
you got me on one thing.
the rotation, your right small block clock wise,
big block counter clock wise.
My Bad...
The green/red stripe wire is never used for anything on a 4 pin ecu. It would only be grounded though the 5 pin
box to whatever the box is mounted to and only in use
with a 5 pin box after it supplies low voltage power
to the box, other end of that green wire runs to the top side of the 4 post ballast (on one side of the ballast>
one to box, one to coil> other side of ballast is
the "run" side and is spiced together). So calling
the green/red stripe a grounding wire in not correct
since that is not what it is used for, unless your
trying to burn out that side of the ballast if
hooked to a 4 post ballast.
Yes, some OEM wire harness use a differant color code
than what comes with the OEM aftermarket kit, however,
all the wire harness have the 5 wires regardless
of if its a kit with 4 pin ECU or the OEM system.
Grounding issues crop up more often with the ECU
than burn out ballast in my experance (though
failed ballasts are not uncommon and I
do keep one around "just in case") do to rusted
joints in body panels on the "un-restored".
It is my preferance to
ground the box direct to the neg battery post
thus removing most or all dought about ground.
This can often be done very cleanly by running the
wire within a wireing loom that supplies other
things.
In referance to your wrenching since 62 and always
finding the ballast to be the problem> I have found
that in the case of not starting at cranking and releasing the key can be caused by a bad ground
to the ECU box (my 65 Ply had that issue)and that
there are a number of other times I have solved
that issue for others with the same problem
when the ballast was just fine.
So, keep it in back of your mind, it may just
crop up someday for you.....
Really, when it comes down to it, checking for
a bad ground is pretty easy, just take some
wire, attach to neg side of battery, clip
end to area needed to be ground.. shows up
pretty quick.... |
