Signal wire to tachometer

[Parachute Adams]

First, I tested my tachometer and it received power but no signal. So I had local shop replace my bad rectifier and tested stator which is good.

Upon testing after repairs the tachometer still receives power and no signal. So obviously there is corrosion in the remote control area where the tach harness is connected.

Here is what I'd like to know:

I don't want to open the remote control and verify my thoughts that there is corrosion; too much of a pain to deal with opening the remote control.

Now, can I directly run a signal wire from source to the tachometer?

I think I can run wire from the Terminal Block directly to the tachometer. Correct?

Please help, and thank you for the help

I think I've found the answer but I just want validation:

Follow yellow/gray wire from rectifier to terminal block, and here attach tachometer signal wire and run to tachometer.

Validate thanks!

Engine manufacturer and model might be helpful perhaps.PoI

That's exactly what I was going to suggest.... Just disconnect the existing wires in case there is a short anywhere...

Or just meter that wire from that point (rectifier) to the back of the tacho.... and then check it's not grounding too...
