defunct tachometer

[Saandy]

hi guys:
does anybody have any ideas as to why the tachometer quit all of a sudden?
it seems like something, some connection opened up all of a sudden, traces of reaction when accelerating suddenly, possibly from vibration.
any suggestions will be appreciateed.

Hi Saandy,
You don't say what type of vehicle you have but some pick up a feed from the alternator so check these connections first. I'm sure the electrical gurus will be along soon.
