Default cruise control transducer

Gents; I looked around and couldn't find what I'm looking for.

Yes, Typical failure mode; Speedo/odo quit. 82 CE 17,800 miles.

I am familiar with the troubleshooting procedure...check cables, if they're
okay, its the transducer.

Fair enough....I don't even mind buying a new one.

WHAT EXACTLY FAILS?....driven gears? I figure it's a 1:1 gear set.

Has anybody actually tried to fix one? It's the curiosity that's getting to me.

I have an old saying (because I'm old, I guess, LOL)

"Nothing is ever broken, until I SAY it's broken".

I am not worried about where or how to buy a replacement....I want to try to FIX the one I have.

This thread WAS helpful...but its about troubleshooting and removal...I am asking for someone who ACTUALLY repaired theirs.

Jeez, I'm a mechanical engineer how hard can this be!

Can't put my hands on my '78 (likely the same component was used thru '82) factory service manual to check just now, but there's a genuine chance this repair might be found in that for your year. HTH

The transducer gets dirty , pull it apart and clean it , not sure if it's the same has the 80 but I wrote an article on how to clean it , have a look here at Ron's tidbits

The "new" transducers available are remanufactured so they can definitely be repaired.

Hi Ron

Great write up.

With the unit in my hand, should there be some resistance when spinning the brass bit that the cable slots into in my fingers?
I am guessing so as the magnet sandwiches the the copper disc between the plates?
My lower cable spapped and i dont want to just fit another if the transducer unit should be free moving in case it snaps the new cable too.

regards

Norman

You'll have to open it up to find out if there is any internal damage.

This may help you. Willcox Corvette has provided the setup manual for both non-resume and resume cruise systems.
