i got one there for like 4 dollars. Another one I got there was about 10. it is what it is, cheap Chinese crap (C^3), but it is better than no meter. It gets me by with some of the basics i do until I can flip the bills for a real meter. The microprocessor would like like a computer chip basically. it would be built into the gauge cluster most likely. This is a part that would not be serviceable and require replacing the entire cluster were it bad. Lets hope that is not the case.

Cheerz!
