Wiring

When I turn the key on there is no
check engine light no battery light
and it does not charge when I
start it and it has a new alternator
on it checked all relays and fuses.
No power in The wire to kick the
alternator on and traced it back to
a relay under the dash power on
one side nothing on the other. ARe
all four terminals supposed to
have power with key on on the
ignition relay?? Where do I go
from here???
