Hey all.
Hello.
The 85MPH electronic speedo in my 1980 SC is loosing teeth off the odometer gear like a centegenarian. I'm going to get another gear and fix (see pict).
However, I purchased a 150MPH replacement. It "works," but the needle is going as far in the 150 as it was in the 85, and thus reading WAY high. So, question is - can I calibrate the 150 (there's a potentiometer in there - see pict, what is it?) or do I need a new sender (ugh!)?? How does one simulate driving... what voltages applied to which leads.. pulses?
Thanks for any advice.
-John.
