sped

Had the '85 300TD in for the speedometer and now the gauges don't work. They say it is my problem now! Is there an easy fix? It looks like a ground fault, when you flip the turn signal some of the gauges move.

Thanks for replies but please don't tell me to take it back, it’s way too late for that now.

I believe there is a fuse for the instrument cluster, check that first.
If the fuse is fine, then pull out your guage clluster and check the round multi pin connector on the right side, if this is loose then you won't have any guages.
Does your temp display and economy meter work?
What about the lights in the cluster along with your gear shifter and radio lights?
When you turn the key on do all the fault indicators light up along the bottom?
Does your tach work?

Reason I'm asking is that all of the above have seperate connectors in the back of the cluster.
