TC , Ive seen this happen before in 63 year "E" models 637867 to be exact QEC on specified engine installed after returning from Texas solder job at cannon plug at Tach Generator not tinned and only held on by a couple strands of wire also look at cannon Plug by indicator in cockpit another area where a lot of hands get in there swapping indicators and pulling on the harness. 

It was C-130B ac and You are right. That was harness problem. Now ops normal.

Thank you sir.

Hello sir...rpm nil during starting and it jumps to normal ops when releasing the break for takeoff run.

I've checked the contunity between ind and techo plug found normal.

Techo gen swapped with svc one.

Also rpm ind swapped but prob remains same.
