Sounds like you have a wiring problem.

Subject: Re: OXS light
When I turn the key, the oil light blinks, the coolant light blinks, the
alternator light comes on steady, and the OXS light stays off.? When the
OXS light flickers, the alternator light does not - it stays off.? I think
my problem is just mileage counter and/or wiring - the alternator seems
fine.
(A couple of years ago I had the alternator replaced, and the shop hooked
it up poorly (poor connection).? It made the fridge relay chatter, until
the connection was fixed.)

Any chance the alternator light is flickering with the O2 sensor light?
Is?
the alternator warning light working? The O2 light goes on with the?
Alternator light as a bulb check. When the ignition is turned on, before
the?
engine is started, the alternator light and O2 light should light solid
and?
the oil pressure light should flash. So should the high temp/low coolant?
light in the temp gauge. these should always be confirmed.?
?
The alternator and O2 sensor lights flickering is usually a sign of an?
alternator problem, often caused by worn brushes. The blue/white wire
going?
to the fridge relay under the drivers seat is part of that circuit. When
the?
alternator starts charging, the back feed from this circuit operates the?
relay. this ensure that the fridge only operates when the alternator is?
charging. Thus if the alternator fails, the fridge turns off.?
