Beside the alternator and battery, one more thing to check is the
fridge relay. At least in my '82 Diesel it is driven directly from
the same signal as the alt indicator. If the relay pulls too much
current (or wiring is somehow bad) the alternator won't regulate
right.

Try to disconnect the relay (it is located behind the drivers seat under
the lid behind the seat) and see if alt problems go away. (now obvioulsy
the fridge won't work on 12 V)

Cheers,
Martin
