Medallion gauge issues

I recently purchased an 02 tournament team 197 and the gauges are giving me issues. When I turn the key on all gauges flicker but then do nothing. Except for the volt and fuel gauge. I believe they are reading correctly. I have checked the inline fuses and unplugged all locations. There is no corrosion what so ever and all terminals appear to look as good as new. I popped open the mdc and it looks brand new. No noticeable shorts or heated areas. I found a troubleshoot document for the mdc but it is for an 18 pin connector. Does anyone have a pin out of the paddle wheel only unit? My connector has two rows 24 pins I believe.

Check the Deutsch connector along side the engine by the starter in the harness.Mine had 6 wires and is capped off.When opened it was badly corroded.Took me 3 weeks to find it and I had same issues as BLAKE903

Full pass this is a well discussed topic. My 2003 197 had issues for nearly a year off and on till I discovered a black film that I'll call corrosion on the end of one of the in line fuses. Cleaning the end of the fuse solved all my issues. Another member resolved his issues the same way after I posted my resolution.

I do have a troubleshooting guide from Medallion for the 2003. Post your email and I'll send it to you

I have removed the stepper motor from the board..just need to put new one on…if it doesn't work, I will clean the fuse…then probably kick myself in the walls.. but will say it did act like a broken stepper motor, stick in different places, and just do crazy things. Thanks, time will tell.

I am having the same trouble with my 02 TT. Everything works but the Speedo. Last time I took it out, the guages were fogging and the next thing I knew the glass cracked on all of them and the Speedo quit. Do you mind sending me the troubleshoot guide? [email protected]

in my experience the MDC needs 13V or more to work properly. I can say categorically that at 12.7v mine does crazy stuff.

There are lots of posts regards troubleshooting the MDC, pretty much all angles have now been covered so should be a great resource for you.
