my tach oil pre and coolant temp do not work does any one have any ideas tryd to fix it but im not getting any where

 

Model and year of car?

 

Have you removed the gauge cluster to make sure everything is plugged in correctly?

 

93 rx-7 sorry about that i forgot to mention that.

 

yes all plugs are ok and powers and ground are good also.

 

i've been having this problem with my gauge cluster problem for months and cant seem to fix it has any one ever had there oil pressure coolant temp and tach not work at all please if you have any insight let me kno thanks

 

Not familiar with the FD cluster, but is there a meter fuse? Maybe also pull the cluster and make sure that none of the solder joints are broken.

 

I would take the gauge cluster out and get in the with a DVOM and start testing the circuit board, circuit wires, connectors, etc etc...

The fact of the matter is most circuit problems typically are caused by loose or worn connections, however that may not be the case here.

 

ok try to stay with me on this one 93 fd my gauge cluster oil , ect , rpm , gauge are not working sent it out to get rebuilt they told me ( cant fix it parts out dated ) so i thought there was something wrong with the cluster because they said they couldn't fix it i bought another cluster online installed it same problem so im getting away from a cluster and going toward wiring i've have tested some power and grounds and im hitting a stand still has anyone heard or have had this problem before ?????????
