Sounds like you have a "one wire" alternator. It only requires the
connection to the positive side of the battery (or ammeter).
If you hook the ammeter up backwards nothing terrible happens. It just
indicates backwards. If there are no + or - markings on the connections
just hook up both sides and wait until you get the rest of the electrics
installed. Then honk the horn while watching the ammeter. If it goes
towards the discharge side (-) all is well. If it shows a charge reverse
the wires.

Subject: [oletrucks] Chevy Duty wiring harness conundrum
-----BEGIN PGP SIGNED MESSAGE-----
I've noticed some mention on the list lately about installing the Chevy
Duty wiring harness. I, too, am installing their harness, and I'm about
2/3 done, but I have a couple of quick questions:
The harness comes with two wires that connect to the alternator. One is
#3, which connects the ammeter to the "screw lug terminal" on the
alternator. This wire is exactly the same as in the previous setup. The
other wire, however, connects the ignition switch's ignition terminal to
this weird little plastic "2-way connector," to the "screw lug terminal"
on the alternator. This wire was not in place in the previous setup --
what should I do with it? (I should probably mention that I have a
key-start 12V setup.)
Also, on the ammeter, which terminal is the +, and which is the -?
Thanks!
