Could well be a charging problem -- bad brushes maybe?  Check system
voltage while the light is on, see if it's charging -- that is, after
all, what the light is supposed to be telling you.

(Any time the ALT light is on, the OXS light will also be on --
that's for bulb-test purpose.)

Unplug the coolant level controller -- if it still behaves that way,
the problem is internal to the gauge.

Intermittent connection somewhere...trace the wiring after it's quit
but with the key still on, see where it's dropping out.

It's not "supposed" to, but it's quite ordinary that it does.  The
reason is that the 7-amp draw of the DC heating element shifts the
fridge ground level slightly positive, which has the same effect as
the thermocouple input going negative (as it does when it's in the flame).
