hello,
I have a 91 RS 5.0.
My speedometer doesn't work.
The needle flip to far right and doesn't come back.
It does not work whether the ignition is on or off.


So I checked the resister on the board.
Then I found that the resistance value of the large register is 0 ohm.


Is this the cause? .
The resistance is said to be 30 ohms or 3.9 ohms, is 3.9 ohm correct? .

Any help, troubleshooting would be great.
Thank you

It may be a mistake that I said 0 Ohm.
When I measured the resistance value, I set the range to “1 kΩ”, so I might have mistaken 3.9 Ω for 0 Ω.
Maybe the resistors are not crazy...
So why does the needle swing to the right?
