Richard and Dean,

Thank you both for your replies.  The dash light flashed intermittently,
with no discernable "pattern".  I removed and replaced the flasher unit just
for the heck of it and haven't noticed the indicator falsely coming on
again.  If the flasher unit isn't dodgy, then there MUST be a short
somewhere, but it's probably going to be difficult to spot since the wiring
harness is nearly new and appears to be in very good shape!  I've got my
fingers crossed that the problem is gone for good, but this isn't the first
time that I've had strange goings on with the dash turn indicator.

When I first replaced some burned out signal bulbs and replaced all the dash
bulbs shortly after acquiring the car, the external turn signal lamps would
all function correctly, but the dash indicator wouldn't flash at all.  Then,
it would sometimes.  Eventually, after a week or two of driving, it came on
consistently and correctly every time the turn signals were engaged.  Now
apparently, the once-dormant dash indicator light comes on as it sees fits,
regardless of whether or not I engage the turn signal stalk!  The Lucas
phantom strikes again!  I'm really hoping that removing and replacing the
flasher unit did something, but I won't hold my breath.

Best wishes,

Jeff in San Diego
