Last week I lost the lights (both) in my speedo. I pulled the gage cluster on Saturday and installed new bulbs (believing that to be the problem.) Well, they still did not light up. So I took it apart again and did some inspection. It appears that some of the copper lines on the circuit board (I know its not a board, more like plastic sheet with copper lines) coming from the tach side to the speedo side had some green corosion and what looked like a break in the copper. I am assuming this is my problem.
Question, is this common? Also, assuming this is my problem, is the plastic film with the copper lines available anywhere other than a bone yard?
Also, anything else I should consider?
