'86 Spider intermittent tach...

[JeffreyOlson@domain.elided]

The only cable is the speedometer drive cable off the 
transmission to the electronic unit for the 
speedometer.  Your solution would help with an 
intermittent speedometer but what about the tach?

Where's the input for the electronic tach come from?  
Does it share the plug-in connector near the speedometer 
cable?

I still think my problem is within the instruemnt itself.

Thanks!

Jeff

A tach in a mid 80's Spider can act up sporadically due 
to the drive cable
backing out of the sending unit (mounted just in front 
of the master
cylinder). The factory speedo cable is actually a bit 
short. A quick, cheap
check (and fix) is to disconnect the cable, slide a 
couple of tiny o rings
over the cable down to the cable sheath, then reinstall. 
The o rings push
the sheath back, forcing more of the cable into the 
sending unit. Fixed
mine years ago.
