Tach will not work. Anyone know of the specific wire or wires that control the tach... I need some new ideas....
Thanks
In advance...

 

Check the condition of the yellow/blue wire at the trailing coil connector. The tach signal is yellow/blue all the way to the cluster.

 

Well Actually the only gauge on my cluster that work is the speedo, The car is an 87 turbo 2. I will check the yellow/blue wire though.
Thanks

 

I believe it's the 7.5 amp METER fuse in the fuse box next to the driver's left foot that you should check. It's in the FSM in the BODY ELECTRICAL section.

 

Yeah the fuses were the first thing I checked. The blue/yellow wire, I found two on one of the connectors for the trailing and another by itself unhooked coming from the harness by the coil. Which one is it?

 

I still cant figure out what is up with my tach situation. The wire aaron suggested is plugged in and in good shape... so what gives?
Thanks in advance

 

you are not getting any power to the cluster. The speedo works since it is cable driven.

 

bad/loose wiring. check the connections on the back of the gauges. they could be loose. if the wire aaron suggested is looking nice and none of the gauges work its something to do with wiring

 

Thats the next thing I am going to do is tear the dash apart and hunt for bad/loose connections. Has anyone ever heard of the cluster itself going bad?
Mine lights up fine its just the gauges are motionless...
Thanks
