So here is where I'm at now.

By taking from Art at this URL: http://cleanflametrap.com/speedo.html

I was able to prove that by putting just a voltage across the two contacts of the speedo motor itself that it indeed is dead.

I set my power supply to 0 Vdc and current limited it to 10 mAmps.

I then turn the voltage from 0 Vdc up to 1 Vdc and according to Arts note's I should have seen some deflection on the speedo. I saw nothing.

I then tried this with my other speedo motor and again I saw nothing, thus the one I put in last night was bad and I didn't know it until this morning.

The measured resistance across the speedo motors was 91 and 93 Ohms respectively. A co-worker of mine, we are both EEs, stated that for a coil that appeared to be somewhat high at least in his opinion.

Therefore tomorrow, I'm going to drive the car in to work and take the cluster in with me so that I can test the working sedan motor since I know it works.

I guess a good question here is would VDO really make two different speedo motors for Volvo, or would Volvo handle the difference between the sedan and wagon on the PCB that contains the Odometer motor? Any thoughts here?

Thanks for listening.
