Does anyone know what voltage reading should show on the circular plug for VSS with green wire, behind the cluster? Mine shows 7.7V with key in position 2, seems weird. I thought it's speed output.

Cruise control module plug shows 10V DC at pin 11 (speed input).

All wiring around looks good.

I replaced the speedo cable again, nothing helped.

So:
- checked fuses,
- checked cluster PCB
- checked with another speedo cable
- checked with round plug disconnected
- checked with round plug connected, but everything else disconnected.
- replaced speedo with another good unit,
- replaced cluster enclosure,
= all of this causes the same issue, no speedo, but odo works. Since odo is mechanical, that means it is receiving the cable input.

However, speedo works in 3 circumstances:
- when tested in cluster outside the car,
- when placed in car without the cluster
- when cluster is gently pushed on the left side. When you stop the car for more than 10 seconds, it stops working.
- when you go over speed bump fast, it starts working, alternatively slap the dash above speedo.
I also connected a 300E cluster, but did not push it in. Speedo worked every time.

Since odometer is working, the transmission end must be getting good grip. Waiting on used gauge set, will post results. Probably the problem lies in there.
