I just bought my delsol and the rpm gauge does not work at all doesn't move all my other tac work...speed...gas...temp...any ideas if its the tac or ground or maybe distributor wire prob??

 

your "rpm guage" is your tachometer or tach, the entire unit is a cluster, there is no way for us to answer this question for you. what we could do is offer solutions based on troubleshooting youve done.


you've apparently done none.

 

Ya obviously I just bought the car last night and im looking for troubleshooting not technical terms about the cluster and what it is called..
