2004 Chevy Tahoe: lost power 60 mph tachometer figuring

Posted on Feb 6, 2014

A 2004 Chevy Tahoe that totally lost power. I was driving at 60 mph and watched my tachometer drop to nothing. It has been in the shop for three days now, and they are having trouble figuring out what is wrong. They have tried a couple things but the engine cpm fuse keeps blowing out. Any thoughts that may help The 30 amp MAX fuse in underhood fuseblock from here appears to be going directly to connector

C1 at the interior Instrument Panel Relay Block and then to the Trailer Wiring. To be sure we are on the same page, can we verify that I am looking at the exact circuit that is shorting the MAXI 30 amp fuse. It should be labeled STUD #2. Circuit 242 3RED wire. Trailer 6-way brown may be area of short. Could be upstream or downstream of this area, but need to get to here and isolate at IP RElay Block connectors to be sure. I hope we are on the correct circuit. The information I have here tell me this is the only MAX fuse 30 Amp in the underhood fuse block. And the information I have here tells me that this is the circuit to focus on. I am going to spend some time on the "U" codes for you next, but it is possible that finding this short on the STUD #2 30 A fuse may lead us to the other problems. If for any reason we are not on the correct MAX fuse circuit, let me know. I gather my information from All Data, and small error by them on say STUD #1 or STUD #2 can lead us way off in the wrong direction.
