Try operating the hazard switch half a dozen times and see if thing 
return to normal.

I will give that a try, along with a few shots of contact cleaner.  That
does sound much simpler than a disassembly!
Thanks for the suggestion

Re: [MBZ] errant buzzer

2006-01-29 Thread BillR
The battery is about a year old, and has always been strong.  But as you
mention it I noticed that for my second start this morning [first start was
fine when I moved EM from the shed to the driveway to troubleshoot the
blinker / buzzer] it cranked very slowly for a few turns - longer than it
has ever taken start.  Turned the key off and on and it started right up as
usual.  I'll have the battery checked also.
Thanks -
BillR

Hwo old is your battery? Is this happening only on your first start of the
day?

A couple of weeks ago my '81 SD started an occasional weak buzzer

under the dash.  It was rare and brief at first, and stopped when the
blinkers were activated.  It has gotten more frequent and longer 
lasting,
and this morning when I turned the key the left blinker came on and

not quit.  A bit of fooling with the turn switch got it to go back to 
an

I could hope it is something that sounds easier.  Any other 
suggestions?


As has been mentioned before, first potential culprit is dirty contacts
inside the hazard switch, second is a bad battery or contacts to same,
and third would be a bad blinker itself.  Note that my experience with
our 560 SL and my attempt to make a louder clacker for top-off driving
indicates that a slight load on the blinker itself (such as a dirty
switch that has some conductivity when it shouldn't, or a badly-placed
extra relay there for noise purposes) results in a weird muted buzzing.
That'd be my fourth suspect.
