After replacing my alternator, everything seemed fine except now, my tach and my temp gauge no longer work. I've checked my fuses and they are fine and my speedo and fuel gauges work, so I am wondering what could be causing this.
Is this condition caused by a bad relay or have I killed/spiked my gauges and they need to be replaced?

I've looked through my factory service manual, but as always, it's information overload and I am not finding what I need. Any ideas guys?

 

Probably a bad instrument cluster..j-yard time

 

Temp wire, tacho wire loose?

If gauge, then theres a broken filament...

Were you able to solve this problem?

I am having the same issue.

Thanks

 

No change. I've not had time to try and deal with it and since it is not
preventing me from driving the car, it's not been the highest priority.

I think I am going to try and get a set of gauges from someone here or
on fleabay and replace them. I must have spiked them when I was putting
the alternator in, forgot to disconnect the battery (old age moment) so
when I was hooking up one of the leads I got a nice spark...which may
have been when I spiked the gauges.
