Speedometer

["Armand Eshleman" <aje1@xxxxxxxxxxxxxxx>]

That was really weird. Last night I went for a ride in my Javelin (1970).
When I left the speedometer was working fine. About half way through
the cruise I looked at it and it had stopped functioning. I've never had
the dash apart. The car has 105,000 miles. Taken very good care of. I
installed a new cable when I swapped in the T5 manual. The gears all
looked good in the transmission (no teeth missing) when I was assembling it.
I have no idea where to start looking for potential problems. I will pull
the
drive out of the back of the transmission tonight and check it out. I took
the
cable off the back of the speedometer after my cruise last night but noticed
nothing
unusual. Is there something inside the speedo itself that may fail? If so,
is it fixable?
Open to suggestions and asking for help,

Thanks,

Armand
