The speedo was completely dead and roached out with rust so I purchased a new one. It lights up now and all appears well, but the needle doesn’t move when driving. Is there any reason to think this is anything beyond needing a new wheel speed sensor?
I’ve read there are some wiring tricks to these things to keep AWD working when the speedo quits, if the previous owner did any of that, would it kill the needle function on the replacement speedo? The only thing I notice that seems odd, is that there is an in-line fuse added near the CDI area, when I pull the fuse the speedo goes dark. It has two red/blk wires coming into the fuse, and 1 red/blk heading from the fuse up to the speedo. Additionally, the red/yellow wire from the regulator that has a single barrel connection to a red/yellow wire up to the speedo had been disconnected. Should that wire be plugged back in, or is that part of the AWD bypass that might have occurred? Or maybe it’s why the needle is dead? I just paid a small fortune for the speedo so I’m afraid of zapping it! 🙂
I might add that AWD did indeed work with the old roached speedo. I can’t believe it had any real functionality to it left, it was REALLY bad inside.
If anyone can shed any light on this I’d be very grateful. I’m inclined to buy a wheel speed sensor but don’t want to throw another wad of cash into something that I may not need.
Thank you!
