Assume you have an early internal regulator alternator based on terminals
(top, not back) and year ('74)
This is called the two wire alternator. R or 1 hooks up to a keyed
ignition source. F or 2 hooks up to the BAT terminal on the back
of the alternator. BAT hooks up to the battery + terminal,through
the ammeter if you have one.
Hope this helps. On my truck, it doesn't charge right away until
there are some RPM's put on, the harmonic balancer is too small diameter.
Works fine otherwise.
