What would be some of the main reasons that a speedometer is pegged all the way over to the right side, past 120 MPH

This is the state of condition even with the key out of switch, engine not running.

Thanks for the help.

You have a few dirty connections in the plugs the dash cluster plugs into, try some contact cleaner spray and a tooth brush.

Is the needle above or under the "peg" at the end?

I have cleaned connectors where a saw a little green corrosion on the copper.

The needle is above the peg on the right side.

Still trying to find out what is causing speedo to peg all the way to the right, past 120 MPH.

I have noticed another project car that I bought last fall, which I will be working on asap, also has the speedo pegged past 120 MPH.

Any more ideas could be a big help to understand what the problem may be.

I think I read that the speedo goes that way with an open circuit......meaning something is not connected. Most times that means the printed floppy circuit board on the back side of the cluster is messed up.

I found the problem.

When I was swapping out the gauge set with a spare one I had on hand, apparently I rolled the assembly over during the install, causing gravity to pull the needle to the far right, which I did not notice during the install. Once it was there, it stays there apparently, even during use on the road.

When removing it, I notice the needle had rolled back over to the 0 MPH location. So I was careful to keep it that way while I reconnected the gauge set assembly.

Everything is now working as it should. :-)
