Harness Wire Color |
|
"B"/"BAT" |
+12V
Power |
white/red |
| Straight connection the + post of the battery. This wire
is a larger gauge than the other connections. This is the wire that the
alternator uses to charge the battery. You can run a larger wire to
the battery if you don't trust your old factory harness. A bigger wire
would probably be better if you go to a high output alternator and the
wire was white/red stripe. This is a separate post on the back of the
alternator with a plastic/rubber isolator to keep it from grounding to
the alternator chassis. |
|
"E" |
Ground |
black |
| Connection to chassis
ground. The alternator should have a good ground through the block but this
is a safety measure. My car did fine without this connection but I hooked it
up anyway. This is a separate post on the back of the alternator and the
wire was black (of course). |
|
"S" |
Voltage
Sense |
yellow |
| Needs to see the battery
voltage so that the alternator knows when to do its thing. This was the top
of the "T" connector on the back of my alternator and the wire was yellow. |
|
"L" |
Charge
Lamp |
white/black |
| Wired directly to the charge lamp. The other side of the charge lamp
goes through the fuse box to a + ignition source. This was the bottom
of the "T" connector on the back of my alternator and the wire
was white/black stripe. |
|
"P" |
Tach/Accessory |
N/A |
| An extra connection that is an output to tachometers and such on the
280ZX cars. It does not need to be used on earlier Z cars. I bought a
'78 alternator replacement from Auto Zone and it
had the "P" connector (My core did not). Auto Zone and the
other chain stores here sell the same alternator for '78 - '83 Z and ZX. |
