Well I have been looking at this site for some time and finally jumped in and joined. There really is a wealth of information and wisdom here. Thanks for those who take time out to be of help.

I have a 98 Lund Tournament Pro. The tachometer funtions at low RPM's But not at upper speeds. It will just fall flat. The dial that is. I did check the ground comming off the tach back to the ground bar under console. It is clean and I used some grease also. I checked the terminals on tach itself. Also my gas gauge will sometimes spike. I was wondering if they may share a ground. Any advice??
