05 DF 140 tach and monitor not working

[bigcat]

My electrical problems started last fall when I lost all my power.
I had this engine installed in 05, the dealer that did the job just tossed the the fused wire for the dash in the bilge
The engine starts with the key and I get a beep.
I do not get any of the monitor lights and no tach.
I chased the wires and every thing looks OK, any Ideas ?
Thanks John.

If it has the SMS gauges then there is a power harness that connects to the hub, make sure harness and it's fuse is ok.

Thanks for the reply, I have the economy gauges that were installed when I re-powered.
What I found when I had the no start issue was the fused wire that was just tossed in the bilge I replaced that fuse and got power to the ignition key.
I will look around a little more for another fuse.
The wiring diagram that I have does not show a fuse,just a plug that is connected to the engine control module.
Is their a way to test the tach?
Thanks John.
